Nyssa sylvatica

Description

Nyssa sylvatica, or black gum, is a versatile tree that thrives in a variety of conditions, from medium to wet soils, and can grow in both full sun and part shade. Native to southern Ontario and southwestern Maine south to central Florida, and extending west to eastern Texas and into upland areas of central MexicoIt prefers moist, acidic soil but is adaptable to poorly drained areas and even standing water. It tolerates drought and is ideal for urban plantings, lawns, or areas prone to flooding. A slow grower, it�s perfect for ornamental shade and woodland gardens. Though moderately messy with fallen leaves, fruit litter, and exfoliating bark, it adds resilience to landscapes, including tolerance to black walnut toxicity.
