Yes, Ive just added Jacaranda mimosifolia.
Then clicked the RHS button and find there are 11 suppliers in the UK
In the master database I had Jacaranda ovalifolia
That is now no longer flavour of the month with botanists, Jacaranda mimosifolia is now its accepted name.
Its also listed in the Chiltern Seeds catalog
Quoting from their catalog:
A Brazilian shrub which, when fully grown, has very large, bi-pinnate leaves up to 18 ins. long, and drooping, silky blue flowers in panicles. When small, however, it is an admirable foliage pot plant that will tolerate pruning to keep it in shape.
Thanks to your contributions, Plumbago auriculata is already entered, linked to your photo.
