Plant Introduction Dates
Mandy Elliott, head gardener at Stoneleigh Abbey in Warwickshire and freelance gardener in other historical gardens, writes: ‘I am constantly hampered by finding accurate dates of introduction for a full range of plants. While I quite enjoy researching introduction dates and am building quite a library in the process, I always dream of a straightforward list/database. Any pointers to such a list would be gratefully appreciated.’
Please leave your comments below.




I have only just found this note. If I am not too late I could offer some suggestions, though I am sure by now you have taken care of it.
In 2003 I published “Tangible Memories: Californians and their gardens 1800 – 1950″. The appendix lists the date of new plants introduced into California.
In 2009 I published “The Global Migrations of Ornamental Plants; how the world got into your garden. In the appendix I have several lists of plants introduced by date.
Other thoughts:
Jim Folsom, director of the Huntington Botanical Gardens, has a fabulous “Plant Trivia ” site.
There is a New Ornamentals Society web site with a great deal of information. You have to subscribe to this but it is very worthwhile.
Another source: Thomas Brown, of Petaluma, California, has prepared several extremely valuable lists of introductions and printed them privately. Copies are in the libraries of the University of California.
I have only just seen the above notes and comments, and as it’s now 2010, it may not be of any interest, but for the past decade I have been building up a database of plant introductions to the UK up to 1800. For the past thirteen years I have been a professional gardener at two eighteenth century gardens and been heavily involved in identifying, sourcing and growing historic plants.
I now have a large database which is constantly being added to – at the moment I am going through 18th C nursery and seedsmans catalogues which are then being incorporated into the main research.
If this is of interest to anyone, please get in touch. I should be on the Garden History Society Researchers list where my contact details can be found.
Karen,
Your database sounds extremely useful. Only this morning I was re-reading John H. Harvey’s book about early English nurserymen. He too lists the dates that some common plants were introduced into the UK.
I have spent the last three years putting historic gardens into the Priory’s land andd I too have much trouble as you do finding acurate dates, I found the “Origins of plants” helpful to a degree and also John Harvey’s book, but no where is there a definitive list, so I am trying to compile a list my self but have only just started. I would really apreciate any help with this.my gardens span 1154 to th 16th century.
One wonders whether the RHS or RBG Kew have ever prepared such lists. They are perhaps the most appropriate institutions to do this. Almost everything of importance entering the UK passed through their hands. The information must be in their collections, either in the libraries or the Kew herbarium. Such lists would be superior to all our piecemeal efforts, no matter how worthy!
Does anyone have any connections to either organization? Could someone set things in motion?
Should we all sign a joint letter to them: Karen, Dawn, Mandy and me? Perhaps a graduate student somewhere is looking for a topic.
Any comments or ideas?

I am head gardener at Jane Austen’s house museum and I also have been researching plant introduction dates for 10 years as I have very nice labels in the garden and do need these dates on the labels. I do feel that our visitors need to be educated and they are pleased to see informative labels. The garden was supposed to be just the Regency era, but that did’nt give very many different plants without lots of repeats, so the plants here now go back quite far, to AD 1,000 . After all these years, I have devised my own dates lists, but I do often come up without knowing the dates of certain plants. I do agree with Judith Taylor (May 20th 2010). Would it be possible to contact horticultural colleges, RBGKew, RBGEdinburgh or RBGKew at Wakehurst about plant lists. I would’nt mind getting the ball rolling or we could all of us send our lists to each other and see if that makes a substantial list that could perhaps be published in some way. It would certainly be a very nice project for a student. Comments anyone ? Yours Celia
Celia,
Thank you for your excellent suggestion. We almost have a critical mass of devotees with lists. I am only a rank amateur in this company. You guys are working with the actual plants themselves everyday but I thought I might send a note to Chris Brickell who is in charge of the National Plant Heritage organization and see how he thinks we could proceed.
regards
Judith
Judith,
I think that that is a brilliant idea to get a well known person involved, as He should have many contacts and/or ideas of his own.
Lets hope something comes of it.
Celia
Celia,
I sent Dr Brickell a note yesterday but he is away at present. I will let you know when he replies.
Judith
Dr Brickell sent me this note:
Dear Judith,
Thanks for your e-mail with details of the plant introduction dates on the Garden History website which I will be looking at shortly.
It would certainly be a valuable resource to be able to consult a reliable list of plant introduction dates and related data. I am not sure whether either Kew or the RHS would be able to act as a coordinator for such a project – resources are very stretched in both organisations at present – but I will contact Brent Elliott, the RHS historian and archivist to see of he can suggest a possible way forward.
Best wishes,
Chris.
Subject: Plant introductions
Dear Chris,
I thought you might be interested in the comments on the Garden History website about the dates plants were introduced into the UK.
http://www.gardenhistorysociety.org/post/forum/plant-introduction-dates/comment-page-1/#comment-2536
Several garden curators and others are all interested in trying to create a reliable list of plant introductions to use at their various properties. Each of them has a partial list but if all the lists were all melded together a very useful and even definitive document would emerge. It struck me that you could give them some helpful advice about the next steps. I suggested that one of the RHS centres or perhaps RBG Kew might act as the coordinator.
I look forward to hearing from you when you have a moment. I am currently working on the history of the marigold, that much despised but vibrant plant beloved of millions. My book Visions of Loveliness: the work of forgotten flower breeders is in press.
All best wishes
Judith

Well done Judith for emailing to Chris Brickell. I do hope that budgets dont get in the way of this inquiry.
Celia
I have not had time to look at this site since my first comment as I have been very busy with my new business at The Priory, so I am pleased and fascinated by the interest in a subject very close to my heart, albeit I am a completely self-taught amateur.
We have now accomplished opening our home as well as the gardens, to B&B guests and occasionally for events based on Food, Garden, and textile history. My aim is to show people the different aspects, and historic, as well as present day uses of the plants both in our gardens and native habitats.
So far I have designed and planted an apothecary’s garden based on the 10th century St Gall plan, which is overlooked by three beautifully painted Murals, also a cloister garth planted with species which could have been growing here between 1154 and 1538, the period when our home was an Augustinian college. The front of the house has been planted with three different types of knot garden, to show the progression of this idea, and to illustrate the time when the Priory became a private dwelling following the dissolution. We also have a Shakespeare bank, flowery mead, potager, woodland walk orchard wild flower meadow,(in progress) pond margins, and much native planting. At present I am working on the Garden of a thousand flowers which will show the plants used in medieval needlework, dyes design and tolls and fibres. We have put in a 14th century Hortus Concluses (enclosed courtly love garden), and I am planning a ‘Simples garden to show the plants which a local wise woman would pick for her simple remedies. I am hoping to find some help as the acre is becoming too much for me to do on my own, I did have some very welcome help for a few days in the summer from a gentleman who I believe is studying horticulture in Edinburgh, but, still haven’t managed to find regular help.
This is all sounds staggering. Brava, bravissima!
It seems to me that you have the making of a delightful book. Do you have anyone taking photographs as you go along? If not perhaps you could think about that. I can visualize facing pages with the antique images on one side and the contemporary ones from your garden on the other.
You mention help. Sometimes college students who need a place for their practicum are happy to work under supervision.
Just BTW, the term is Hortus CONCLUSUS, but I expect you knew that.
Have you come across Katherine Swift’s “Morville Hours”? She chronicles the creation of an extraordinary garden from scratch in Shropshire. It is a very beguiling book and doesn’t even have a single photograph.
So far I have not heard anything from RHS about the master list. Everyone is short of staff and time.
Warmest wishes
Judith
I have not so far come across Katherine Swift’s “Morville Hours”, but thank you so much for the tip I will certainly follow this up.
I have started my research into introduction dates as an integral part of my plans for The Priory gardens and it is now in danger of taking over as I have found it to be a compulsive part of my wish to convey an understanding to people about the plants in our surroundings. Ideally I would wish to involve local children, as well as adults and have them gain at least a basic knowledge of native flora as well as the uses of plants they see around them. I am compiling lists of plants beginning with native British and then moving through century by century, detailing the origin, culinary, medicinal, and legendary magical uses, as well as the essential oil properties dye properties and many other uses, to give a full C.V. of each plant.
A mammoth task and one I do not in any way expect to complete alone, I think I would be pleased just to get as far as I can.
I believe it is vital to give time to close attention to plants to carry on the work that was started so many centuries ago and that has slipped into the margins of our busy modern lives.
Well, Dawn, the amount of projects and work that you have taken on, simply dwarfs me in my Jane Austen garden and makes me feel quite insignificant and I admire your every move. A gargantuan task indeed. Keep on with the good work. Best wishes Celia
I wonder if any of you can help me with one of my many conundrums. During my research into plant introductions I have become increasingly confused by Dipsacuss fullonum, Dipsacus fullonum ‘fullonum’, Dipsacus sativus , and Dipsacus sativus ‘fullonum’I started off by thinking it was strange that a plant with such soft spines could have been used for either the purpose of fulling cloth or carding fleece. As a spinner I had a trial pair of carders made with Dipsacus fullonum which at the time was the only teasel known to me. Then one day whilst working at The Eden Project I saw a different kind of teasel with straight spines and a much more rigid form. I was intrigued and eventually managed to grow some of each type in my own garden. It then became apparent to me that there were two distinct plants, one fit for fulling and one most definitely not.
I have subsequently read that there are two plants and that much of my confusion is shared by others. However I am still not quite certain of the correct botanical name for the lesser known rigid plant. I have at various times been lead to believe that Carle Linnaeus is to blame by wrongly naming the wild teasel fullonum, when actually the fullers teasel is stuck with the appellation ‘sativus’. Help!!!!!!!!! I would also like to know if the fullers teasel i.e. Dipsacus sativus is a native or if it was developed through cultivation, or crossed with an ‘outlandish’ species.
Check this link: http://www.ars-grin.gov/cgi-bin/npgs/html/taxon.pl?317322
It describes D. sativus as cultivated, possibly of Mediterranean origin. If you go to D. fullonum in this same site, you will see it is considered to be a noxious weed in the US and native to several disparate parts of the world.
GRIN is one of the most useful databases I have ever found. It is only matched by the Missouri Botanical Garden’s TROPICOS

From Chris Brickell
Dear Judith,
Just a quick e-mail to thank you for the information on the recreation of this mediaeval garden – certainly a fascinating story and well worth a visit in due course.
Best wishes,
Chris.
Hello people,
I have read all these interesting comments and i am looking to see if possibly that you or you know of anyone that has possibly put together a list of plants for plant introductions of japanese plants to the UK or a specific part of Japan as this is what a am basing one of my FdSc hort modules on if i can find information of this!
Thanks very much Kierin
Dear Kierin,
It is good to hear from you. We are like the blind men and the elephant. Everyone has got hold of one or two bits. That is why it makes a lot of sense to put it all together in one place but so far there is no way of doing this.
The most important plants from Japan are probably azaleas. Many azalea hybrids came from Japan where azalea has been bred for hundreds of years. A lot of the plants were originally from China but had established themselves very successfully in Japan.
The Kurume series of evergreen azaleas is an example. Ernest Wilson was the first to introduce them to the West. The Kurume azaleas were developed by Motozo Sakamoto, a Japanese nurseryman. He raised and selected seedlings of azaleas growing on the sacred Mt. Kirishima.
C.E. Lucas PhiIlips, a noted rhododendron expert and Peter Barber, who managed Exbury Gardens, have left a very valuable (and revealing) description of Rothschild himself and his methods of plant crossing in “The Rothschild Rhododendrons: a record of the gardens at Exbury”. Rothschild worked with the Knap Hill crosses developed by the Waterer family.
Koichiro Wada, 1907 – 1981 sent the first specimen of R. yakushimanum, one of the R. degronianum group, to England in 1934. It had been identified in Japan in 1920. This species is only found in a minute niche at the very top of a tall mountain on Yaku Island.
There are conifers and ivies from Japan, also many types of maple tree.
I am sure the other people who have been part of this blog can tell you a lot more than I can.
Judith
Hi Judith,
Thanks very much with the comment, it has given me a little light to search for those plants but i am still in need of anyone that possible knows more about Japanese plant introductions! If anyone could please give me any information would be very much appreciated!
I see that most plants are coming from China but there is also limited information i am able to get from this as well!! I hate introduction dates sometimes!! haha
Thanks Kierin
Hi Kierin,
I’ve just caught up with the recent comments and your question about the introduction dates for Japanese plants.
I’ve never come across a comprehensive list of these plants, but wondered if you had read a book by Alice Coats called ‘The Quest for Plants’ – she has a chapter on plant collecting in Japan, from Kaempfer in the late 17th C onwards, which might give you some pointers. Failing that, trawling through the five volumes of William Aiton’s ‘Hortus Kewensis’ would be rather time consuming (and fascinating), but is probably the most comprehensive list of pre-1813 introductions. Similarly, Curtis’s “Botanical Magazine’ would be a good place to look – the Lindley Library have a fantastic set!
My area of plant introduction work is primarily pre-1800, and there certainly were very few plants coming from Japan at that time as it was closed to most Europeans. Those I have come across include:
Aucuba japonica (intro. 1783)
Ginkgo biloba (intro. 1754) – this may well appear in early lists as Salisburia adiantifolia
Chimonanthus praecox (intro. 1766)
Camellia japonica (intro. c.1739). This features as Plate No. 42 in Curtis’s ‘Botanical Magazine (Vol.2, 1783), where some details are given of flower colour, etc.
I can send you details of other plants, including herbaceous, but there really aren’t very many.
Hope this might help,
Karen
Hi Karen,
If you were able to send me details of herbaceous plants that would be very much appreciated i am going to have a look at the books you mention and see what i can find out!
The plant planting plans I am going to produce i think i will just choose like 1900’s!! haha much easier and then have a wide choice of almost all Japanese plants!
The trouble is with Japanese plants is that most of them originate from China or China have claimed them to be theirs!!
Thanks very much Kierin
I too have been searching for plant introduction dates. My house, adjacent to an English Heritage property, was renovated for the village miller in 1759. I planned a contemporaneous garden some 17 years ago using as many plants as I could find that were listed in John Harvey’s book plus those on a list which I downloaded from the Chelsea Physic Garden at the time. The garden now needs renovating and I have found Graham Stuart Thomas’s ‘Perennial Garden Plants’ invaluable. My other resource complementary resource is ‘The Hillier Manual of Trees and Shrubs’. I’m a bit surprised no-one has mentioned either of these, which are at least readily available, though not exhaustive, nor in a searchable form. Some patient person is neede to covert them into a database.
Rosemary,
Thank you. You put your finger on the basic problem. There are a lot of data out there but the system for finding things is very clunky.
We have commented previously in this blog that only a large institution such as the RHS can really organize such an effort but unfortunately it is expensive to employ a person to create a database and they are all short of money. I have put in my time turing static lists into databases. I am working on one right now, chrysanthemum breeders before 1900, for a chapter in my next book.
Judith
It may be of interest that in my book ‘The Origin of Plants’ published in 2001 by Hodder Headline and now in paperback published by Transworld in 2004 which charted the intoduction of plants into Britain from 1000 AD to 2000 AD after each chapter there is a list of some of the introductions in each century. In addition I have over the past fifteen years compiled a list of several thousand introductions to which I am constantly adding.
“The Origin of Plants” is one of my favourite books. I mined it shamelessly for a chapter in my book “The Global Migrations of Ornamental Plants”. Your lists were full of interest but not only that, the book was handsomely produced. I was jealous of all the colour plates being next to the descriptions. I am very glad to have this opportunity to be able to tell you how much I enjoyed it.
As I said elsewhere I am not a dirt under the fingernails gardener but an armchair onlooker. i still think that if someone could persuade the RHS or RBGKew or some other institution to take this up that would be the way to go. All the contributions of the people in this discussion group would make an excellent core.
I have been pursuing one particular plant lately without very much success. I published 2 articles on the history and migrations of the marigold, Tagetes. (Chronica Horticulturae March 2011 and Pacific Horticulture October 2010). In spite of all that has been written about these plants no one knows precisely when they arrived in Spain and even less is known about how they got to India and became the most popular plant in that country’s history. Whatever work I have done can only be considered as scaffolding for others to build upon.
I am sad to report that the last year has been very difficult for me and as a result of being unexpectedly left on my own at The Priory I am reluctantly going to have to sell my beautiful 12th century home along with the gardens which I have worked at for the last 5 years. My hopes of showing the different periods of english garden history along with the introductions all named and in context to provide an enjoyable way of understanding the changes in english gardens will have to go, unless any one has any miracles up their sleeves.
please contact me if any one has any ideas.
It was so good to read all the comments about plant introductions, for a long time I thought I was out there on my own! Thank you too Judith for your complimentary words about my first book.
When I began collecting plant introduction dates (originally for Plant Heritage, Hampton court Show) and then wrote about it one of the unexpected delights was realising how sensitive the introductions were to something happening in that part of the world,three plants in say from S. Africa within the space of five years and one can be certain that its the result of trade, war or collecting. It is a different way of interpreting social history.
Gathering a list together is as we all know never ending, but one of the things that might be helpful, is indexing a Collection of the Lists, where they are housed, if they are in the public domain and so on. That would be a start. I am a Fellow of the Linnean Society and I wonder if we could make a collection under their aegis? I live in Brittany and will be in England during November, perhaps those interested could meet and see how we could take the idea forward.
If anyone is interested in taking this further do let me know
Meanwhile have a happy Diamond studied Olympian summer!
Maggie,
Thank you for coming back into the discussion. Your suggestion is very powerful. One of the most useful books I have found is Brodin’s “Guide to standard floras of the world : an annotated, geographically arranged systematic bibliography of the principal floras, enumerations, checklists, and chorological atlases of different areas”
A complete listing of where to find sources is a great step forward. I had thought it could be done with Kew or the RHS but I had not thought of of the LInnean Society.
Do you have any idea yet of when you might be in London? I seldom travel but this is a very enticing possibility. My next book, “Visions of Loveliness: the work of forgotten flower breeders” is at the publisher now and should, if I live long enough, come out later this year. If London works out I would be glad to bring you a copy.
Meanwhile poor Dawn is facing a dreadful problem. I wish I could be helpful there but do not know where to begin.
Judith
Judith, good morning, thank you for your comments. sometime ago I wrote a paper regarding a ‘Plant Introduction Forum’ which you might find of interest, could we communicate by our own emails? Mine is mcc3@wanadoo.fr
It just would be less cumbersome I think?
Real April showers here and so cold, this time last year we were eating outdoors already, no such luck this year it is too cold and so showery. We have seen so far, very few swallows or house martins (and no swifts)!
Looking forward to hearing from you
Maggie
I have found it reassuring that it is not only I who finds this subject so infuriating! Come on Kew! What are you playing at?! This is the sort of basic database the World needs.
I recently ploughed through books and the web to find the origins of various Schefflera spp and, amongst other inconsistencies, found Scheffler to have been born and died in many different years and places and to have had many different professions. I’ve narrowed him down, I believe but it has taken an age.
I, for my sins, AM a hands-on gardener, looking after the interior plant displays at the University of Bath, so time for study is limited, so thank you everyone who struggles to get at plant facts. Anyone want to do my guided walk around our library plant displays in July? I’m calling it “Our Green United Nations” and want to get it RIGHT!
First stop YOUR book, Maggie….and I’ll branch out from there.
Having bought Maggie’s book (excellent!) I now find that a large part of the Garden History Society’s collection of books is held here at my workplace; the University of Bath, shared with York Uni. I will now JOIN the Society so that I feel less guilty dipping into those books.
Delighted to find this web site, however late in the day!
I have almost ready for the publisher ‘A John Clare Flora’ which has nearly four hundred entries of plants he wrote about in poetry or prose or grew in his garden. My biggest puzzle is the cornflower-blue poppy that he found had seeded itself between the rows of vegetables in the kitchen garden of Burghley House, where he was employed in the second decade of the nineteenth century — a century before Kingdon Ward successfully introduced Meconopsis betonicifolia. Chris Grey-Wilson writes that the only blue poppy in the Western Himalayas, M. aculeata, was being cultivated in UK in 1864, but did it really settle then? It was first described in 1834, but I have a hunch its seeds reached Europe long before that because of its reputation as a drug. But if so, did the lords of Burghley succeed any more than Clare did in getting it to acclimatise to the East Midlands? I should be so grateful for any suggestion.
