Leaves of this dogwood have yellow edges.
I noticed that one of the young Cornus florida seedling trees has yellow margins to its leaves. I looked at all the other seed-grown dogwoods. This is the only one with yellow edges.
Variegation does not look like mineral deficiency which
usually manifests in prominent green veins and entire leaf
I searched dogwood diseases. We commonly see the dots of Spot anthacnose and Septoria leaf spot about this time of year, cosmetically unattractive but not deadly. Discula antracnose kills. Powdery Mildew is another problem of dogwoods. None of these cause yellow borders on the leaves.
A look at the full tree. These seedlings are about five years old.
A sister plant about 20 feet away is solid green.
I read about variegated dogwoods, not uncommon. None of the photos I saw looked exactly like this one, but some were similar. Among the common cultivars for sale are Cornus florida "Rainbow" "Welchii" "Golden Nugget" and "Variegata." There were not photos of all.
Another dogwood in the general area with plain green leaves.
Another tree in full sun, lighter green but uniform color.
Another look at the variegated tree. It has put on tiny buds
for next spring's bloom just like the others.
This tree had odd leaves last year. I paid little attention to it.
Does anybody know about variegated Dogwoods?
