The grapes of the Lomanto Grape Vine are a Southern gardener's dream. The self-fertile Lomanto Grape Vine is resistant to Pierce's disease, rot, and mildew. Flowering begins in late April and harvest of the medium-sized conical clusters will begin in early July. The Lomanto Grapes have a thin black skin and a sweet, soft, juicy pulp with few small seeds. The Lomanto has it all.
