Gardeners' Notes:

I loved the foliage on this plant last summer, which prompted me to buy it at my local nursery, and it bloomed great alongside my other Black-eyed Susans. However, this spring it has not come up yet and it's already the end of May. My other Black-eyed Susans (not Marmalade) started growing a month ago and have big healthy leaves. Does the Marmalade start growing later in the season? I'm worried about it. It looked healthy at the end of the growing season last year.

I feel that the black eyed susan's are on par with the coneflowers the purple and the white. The bloom doesn't seem to last as long, but the foilage and stems seem to be the same. I have had great success with the black eyed susans they do move a little into other area's but if you dead head they keep on coming back.
