Gardeners' Notes:

Positive Elinore On May 12, 2012, Elinore from Minocqua, WI (Zone 4a) wrote:

I love this variety! The color is deep and striking. I was surprised that the peduncles are so long that the flowers droop downward a bit. I've come to appreciate the different look this gives the plant, and the pretty way the flowers sway in a breeze. It's a nice contrast to all my other clematis. Also, it's super hardy! Mine is in a raised bed and gets high wind off the lake in my zone 4 yard and still grows beautifully!

I planted this clematis this past Spring and am amazed how vigorous this viticella is...already shot up 7 feet tall and what a delicious deep purple
