Gardeners' Notes:

Bought this plant from a local nursery about a two years ago. The first year it did nothing but hold on for dear life. The second year it bloomed magnificently, although the blooms only reached about 4", no where near the 12-18" it was supposed to get. And then after it bloomed it withered up and died for no reason; every other plant in the bed thrived. I won't be getting this variety of tickseed again.

I bought a nice healthy plant in August, and planted this in a sunny location. About two weeks later, I noticed whitish spots on all the leaves. It looks like powdery mildew, but it doesn't seem to be harming the foliage any. I'm not sure that's what it is and if anyone else has had this happen to theirs, what did you treat it with?
