Yellow Cephalaria is a strong grower thriving in poor soils. Too rich a soil and/or too much water will cause rotting of the flower stems. Self seeds nicely and not invasive. Leave the dried flower stalks on the plant for winter interest.

added July 17 2009: Since this has started blooming I've noticed it's very attractive to bumble bee's! Theres seems to be one buzzing around it every time I look! Even now I just saw one and it's almost 8pm on a cloudy day!
