Dolce Cinnamon Curls is new for me this year and hasn't seen a winter yet, but so far it's doing well and I noticed today it is putting on some nice deep red new growth. I have it growing in full sun from morning until about 3 in the afternoon when the sun finally makes its way around the other side of the house. This time of the year the sun exposure is less than at the height of summer.
I also have Cherry Cola, two of them (number two was a piece of crown that had broken off of number one which I rooted), one in the same full sun bed as DCC and the other in full shade beneath a purple plum tree. Number one, the full sun plant, is not doing as well and the leaves are faded and it doesn't seem to flower that well, but it's still alive. The one in shade has nice color and has bloomed all season long. Both have survived three winters.
I also have Autumn Leaves growing in full sun which I may move if I can find somewhere else for it. The color isn't very good so it could be getting too much sun. This plant is my second attempt at growing this plant. The first one didn't make it through a wet winter (it was also grown in clay soil in a yard prone to flooding at a different house). Number two hasn't seen a winter yet. It seems to be doing okay, but hasn't thrived for me. Like I said, it may just need to be moved to less sun. Also, didn't help that my brother kept trying to trample it every day.
