Gardeners' Notes:

Neutral Dodsky On Feb 11, 2008, Dodsky from Smiths Grove, KY (Zone 6b) wrote:

I've grown Creme De Cassis for a few years. I like the flowers, they are quite eye-catching, but the plant overall looks tattered and can be downright ugly from mid-summer onward. Summers in S. Central KY are generally hot and sometimes quite humid, so perhaps it just doesn't like the weather here. lol I planted it towards the back of a flowerbed so the ugly foliage is partially hidden by other nicer looking perennials.

So far no rust problems, but various caterpillars, beetles, and spider mites attack this plant every year. My plant receives full sun from sunup to around noon in its east exposure location, and receives sufficient water from a drip system. It typically gets about 5-6 feet tall and definitely requires staking.

I've enjoyed the flowers despite the overall lackluster performance of the plant. Most of the flowers are double with some singles ocassionally mixed in.

Very tall 6-8' - plant 18" apart. zone 3-9. First year blooming, with double, semi-double and singles on the same stem. Deep wine colored blooms with pink fringe.
