Great. Thanks.

Interesting article, but it completely fails to mention the simple fact that all the really conspicuously red-leaved plants owe their existence to human selection for a trait considered desirable by many gardeners.

I just found a reddish pink leafed Huckleberry in Redwood National Park. Some folks who work around those parks told me that no pesticides are used in that area that they know of - where that plant is.

Something like Amitrol came to mind. Although anything I've seen with Amitrol pink died.

Anyhow, I'll be keeping an eye on that plant to see if it grows pinkish red yearly.
