Typical Good Purple Leaf Plum
A tree with purple leaf always contrasts pleasantly in the landscape with the usual green trees. The purple-leaved plum is a particularly interesting tree. Mr. Burbank has made experiments in combining it with the usual green-leaved plum. There is an interesting segregation of colors in the second generation of such crossbreed varieties, resulting sometimes in the mottled leaves shown in earlier photos.
