for pointing out premeium
plants is not selling online. That is my third source no longer available for mail or online orders.
Marleine has provided you with a source I referenced - PDN - or
plant Delight Nursery. I could recall PDN but not the full name.
Be aware PDN stock can grow in a
zone with quite a different climate condition than yours. Cultivar stock is not affected by climate growth, while species stock could be. PDN has two informative articles on climate and
zone planting and can help with
zone issues.
The second site is Hallson Gardens:
www.perennialnursery.com - It has two epimedium varieties. Under the perennial link, click on epimedium to read of a possible virus problem. Might be of interest to you as this
plant will go under a fruit
tree.
Garden Watchdog has rating and feedback for both.
