I never had Icy Drift but I had Green Ice and it died over winter. It never got bigger than about a foot cube either. The flowers are very small and greenish white and it bloomed in flushes not continuously. It did black spot some but I don't recall it being terrible. For me though it just wasn't very appealing so I never replaced it. The blooms were just ho hum.

I did see an Icy Drift at the nursery Saturday and it larger larger, both the plant and the blooms. The one I saw had about a 3 foot spread but only about 18 to 20 inches tall. It did have spots on it though.

I never grew Icy Drift but I have grown, and enjoyed, GREEN ICE very much. It is better than average in it's disease resistance and blooms prolifically in flushes throughout the spring and summer. It blooms in sprays and blooms are fully double. The blooms open white and turn a pale green as they age. Blooms remain on the bush in excess of two weeks.

I agree w/ Bob! Of all the Miniature Roses I have planted (& lost a few) GREEN ICE Planted in 2003 is my favorite as well. I have 2 both are the last ones still flushing blooms when all others have started going to bed for Winter! One is in less than ideal site but has never failed to please!!! I have not planted ICY DRIFT either.

FWIW here's my album 2011 ~ some pix are from earlier years!
