Best planted in early spring after your last frost, or in fall before the ground freezes, depending on your climate.

The classic Southeastern US table grape — a genuinely distinct, thick-skinned species, not a "foxy" wild grape — producing large, individually picked bronze or black berries with a sweet, musky flavor, embodied in heritage cultivars like 'Scuppernong' (North Carolina's state fruit) and 'Carlos'. ⚠ Know the look-alike: across eastern and central North America, moonseed (Menispermum canadense) twines alongside wild grapes, carries similar dark hanging clusters, and is potentially fatal. Three checks — a grape has 2–4 rounded, pear-shaped seeds while moonseed has ONE flat crescent seed; a grape climbs by forked tendrils and moonseed has none; a grape's leaves are toothed and moonseed's are not. Open a berry and look at the seed before eating any wild grape.

Growth speed
Fast and vigorous once established, capable of 30 m+ in the wild
Spacing
600 cm (236 in) apart — about 36 m² (388 sq ft) per plant
Leaf shape
Broad, cordate-to-orbicular leaves, glossy dark green above with coarsely serrate margins, mostly hairless beneath, with unbranched (simple) tendrils opposite the leaves
Root system
Thick, phylloxera-resistant roots that allow own-rooted cultivation without grafting, unlike bunch grapes
Fruit description
Large individual berries up to 25 mm across (bronze, black or reddish depending on cultivar), thick-skinned with a sweet, musky flavor; often picked singly rather than in tight clusters
Propagation
Hardwood cuttings or layering for named cultivars (to keep them true to type), or seed (fresh-sown, 6 weeks cold stratification if stored) for wild seedlings
Pollination
SELF-FERTILE (hermaphrodite flowers)

Growing guide

Fertilizing. Muscadines have notably high magnesium and boron needs relative to bunch grapes; growers commonly apply Epsom salts (magnesium sulfate) in early-to-mid summer, and a small amount of borax every 2–3 years before bloom on sandy, high-pH soils where boron deficiency is common — over-applying boron easily causes toxicity

How it spreads. Vigorous woody tendril climber capable of reaching 30 m+ into forest canopy in the wild; tendrils are unbranched, unlike the forked tendrils of most other Vitis species

Growing tips. Carries strong natural resistance to both Pierce's disease and grape phylloxera thanks to thick, resistant roots, so muscadines are usually grown own-rooted rather than grafted, unlike bunch grapes. Needs USDA zones 7–9 and about 200–400 chill hours. Most cultivars bear only female flowers and need a self-fertile ('perfect-flowered') cultivar such as 'Carlos' planted nearby for pollination.

About the data

Zone figures are typical published ranges — microclimate, drainage and siting shift them by a zone in either direction. Store links are found by an automated search, refreshed every six weeks. Availability is seasonal; stock and prices are not tracked.
