I have this filipendula I bought from Bluestone

http://www.bluestoneperennials...

But I cannot find it in the database. But I did find this
Filipendula ulmaria 'Flore Pleno'

Same thing or slightly different varieties?

The Catalogue of Life lists F. hexapetala as a synonym for Meadowsweet (Filipendula vulgaris)

Thank you!

I'm checking to see whether I can find any differences in the Google references to F. vulgaris Flore Plena (or Pleno) and F. ulmaria Flore Pleno. It might just be a case of mass confusion.

I don't know what to say. Some sites list F. ulmaria Flore Pleno as growing to 3-4 feet and other sites show F. vulgaris Flore Plena as a shorter plant, so there's at least a suggestion that they're two separate plants. I'll add an entry for the latter, but we might find out that they're the same plant someday.

Filipendula vulgaris 'Flore Plena'

Thank you Zuzu. I will pay particular attention to measure mine this year.
