Al,

I know that you said earlier this year that the rudbeckia would self sow the following year, but I just wanted to double check this because the Jung seed catalog shows Goldstrum (R. fulgida) as a perennial, although R hirta is listed as an annual. This is my first year to have both in the garden. I love the prairie sun (R. hirta).

This is a picture of prairie sun, monarda, zinnias in my garden. There are some black eye susans just to the right of this picture.

I'm just trying to figure out what is going to happen next spring.
