Gardeners' Notes:

Neutral donnacreation On Mar 14, 2010, donnacreation from Sumter, SC (Zone 8a) wrote:

I planted 4 specimens in partial shade last June and they grew like crazy. They were unfazed by freezes until mid Jan, when temps dipped into the mid teens 2 nights in a row. They are now bleached out, but still green at the base. One specimen that was accidentally mulched with a neighboring plant is still beautiful and green. It was lightly mulched with pine straw and the crown is healthy and dry. If it blooms this summer, I will upgrade my rating to positive.
Update Mar 2011, no blooms last summer, but I plan to feed them heavily this spring. Will post pics if they bloom this summer.
