Ornamental Peppers Sizzle In Autumn

Kousa Dogwood Not Summer Heat Tolerant

Chinese (Kousa) dogwood (Cornus kousa) rates four stars (out of four) as a beautiful small flowering landscape tree. Since the 1970’s, a deadly anthracnose (Discula spp.) fungus disease has threatened to eradicate our native flowering dogwood (C. florida). Kousa dogwood rates as a highly disease resistant alternative. Its Achilees’ heel is its less than stellar foliar heat […]
