A lot of research has now produced a checklist of epithets (names) used for Sweet Peas and other Lathyrus. There are about 7,200 entries in the checklist although most are no longer in cultivation. This work is intended to complement “Lathyrus: The Complete Guide” by Greg Kenicer and Roger Parsons, an RHS horticultural monograph being published in 2021. All the entries in this checklist refer to cultivars and mixtures. For an up-to-date account of botanical epithets, please see "Lathyrus: The Complete Guide".
Three documents are available (for download below):
Alongside the epithets are details showing:
This work is not complete. There are names and sources still to be identified. Roger Parsons would be delighted to hear from anyone who is able to add or correct information, preferably by email to: firstname.lastname@example.org
The list contains a few names which are very offensive. We have included these for historical accuracy. They serve as a lesson on how society once was and to remind us of the importance of equality and diversity issues.
Initial funding and encouragement for this work was provided by Dr. Keith Hammett (New Zealand), Sydney Harrod (Northern Ireland), Roger Parsons (Great Britain) and Dr. Judith Taylor (USA).
Many people have contributed information over the years but the author would also like to thank: Kerin-Lea Hall (Australia), Neil Jordan (Australia), David Lemon (USA), Dr. John Macefield (Great Britain), Roz Marshall (Royal Horticultural Society), Dr. Kaoru Nakamura (Japan).
The work also relies heavily on the archives of the National Sweet Pea Society (www.sweetpeas.org.uk).
