I've recently started adding pictures to your database, including Tree
Peony pictures taken at Cylburn Arboretum in Baltimore. Their
collection was installed in the early 1980s. There are several
(pictures of) that I'd like to add, but can find no reference to
online. They are suffruticosa x :
'Black Sea'
'America'
'Banksai'
'Rose Flame'

The next time I'm at Cylburn, I'll check to see if they can provide
provenance on the plants.
Thoughts on how to add these to the database?

Thank you

Here are links to all but Banksai which I'm looking into.

Japanese Tree Peony (Paeonia x suffruticosa 'Black Sea')
Japanese Tree Peony (Paeonia x suffruticosa 'Beikoku') 'America' is a later synonym.
Lutea Hybrid Tree Peony (Paeonia 'Rose Flame')

Thanks for the help, Evan.

BTW, here's a picture of Banksai

I haven't been able to locate references to P. Banksai. This could be an alternate spelling of P. banksii (P. suffruticosa var. banksii, ...). I'd suggest adding your photo to the entry for Tree Peony (Paeonia x suffruticosa) with a comment noting 'Banksai'.
