The story

California wild grape fed the Pomo, Miwok and Yokuts, who ate the grapes fresh and dried, and its roots were grafted under European vines when phylloxera struck; it climbs the oaks of Napa and the Sierra foothills and turns red in autumn.

Planting

Full sun or part shade, moist to dry soil, and a tree or arbor; plant in spring. Male and female, so plant several or a selected fruiting form like 'Roger's Red'.

Growing

Water the first years, then little. Prune hard in winter; it grows 30 feet a year.

Harvest and use

Small tart grapes ripen purple in early autumn; jelly, juice, and wine. Leaves for dolmas in spring.

What to watch for

Powdery mildew and Pierce's disease; vigour.
