Gardeners' Notes:

I was fortunate to find a small population of Pinxterbloom growing locally on the banks of a small creek. I've transplanted a few and added a larger specimen from a nursery. They're slow-moderate growers in favorable conditions. Once established they're also surprisingly drought tolerant. A native azalea collection is incomplete without Rhododendron periclymenoides.

My husband and I are landscaping our yard with plants native to our area. We came across this beautiful plant while 'shopping' in our friend's woods. We didn't know what it was. We just knew that we wanted it in our yard! Luckily, the soil it was living in (sandy clay) was what we had waiting for it at home :) After a couple of hours of light wilting, it perked right up and is doing great! I can't wait to see it next Spring!

I have a 10 year old plant that has performed satisfactorily every spring -- plenty of blooms that are long-lasting . It has withstood temeratures as low as 15 F here in coastal South Carolina

This native, deciduous, spring-blooming azalea is called "Pinxterbloom" in reference to its bloomtime: Pinxter is Dutch for Pentecost, which is the seventh Sunday following Easter Sunday.
