Rudbeckia Test

fulgidafulgida-versus-fulgida-1200Here are what two versions of Rudbeckia or Black Eyed Susan look like on September 7th in St. Louis Missouri.

One version is the more common Rudbeckia fulgida which I have grown for years. The advantage of this variety is that it’s a native and spreads easily via the roots and is a perennial. It has two disadvantages. Most years it gets a disease and flowers poorly in my yard. The second reason is that even when it is not diseased, it stops blooming around this time of the year.

The other version I am testing is Rudbeckia fulgida fulgida. It seems to be relatively easy to grow and reseeds easily.

As you can see the Fulgida fulgida variety definitely looks better this time of year. It’s not a great nectar plant, but it does attract a few pollinators and might attract the goldfinch.
