Swamp Tupelo (Nyssa biflora) – 3 Gallon

Flood-Tolerant • Native to the Southeast • Excellent for Wetland & Wildlife Projects

The Swamp Tupelo, also known as Swamp Blackgum, is a native tree perfectly adapted to wet, poorly drained areas like swamps, floodplains, and low-lying woodlands. With attractive dark green foliage that turns vibrant red to purple in fall, this tree offers year-round interest and ecological value—especially for birds, bees, and other native wildlife.

Planting Zone:

USDA Zones 6–9. Naturally found in the Southeastern U.S., it thrives in warm, humid climates.

Watering Needs:

Thrives in constantly moist to saturated soils. It is one of the most flood-tolerant native trees and ideal for rain gardens, pond edges, or other areas with poor drainage. Young trees should be watered regularly if planted in upland areas.

Soil Requirements:

Grows best in acidic, wet, poorly drained soils, including muck, clay, or sandy loam. Not suitable for dry, alkaline, or compacted urban soils.

Light Requirements:

Prefers full sun to partial shade. Full sun encourages stronger, more upright growth and better fall color.

Fertilizer:

Fertilization is usually not necessary in wetland settings. In drier or landscape conditions, a light application of balanced slow-release fertilizer (10-10-10) in early spring can promote healthy establishment.

Pruning & Care:

Minimal pruning needed. Remove any dead, damaged, or crossed branches in late winter or early spring. Swamp Tupelo grows with a naturally upright form and needs little shaping.

Planting Tips:

Dig a hole twice as wide and slightly shallower than the root ball.

In wet areas, plant slightly above ground level to improve root aeration.

Backfill with native soil—no amendments required.

Water well after planting and mulch with 2–3 inches of organic material, keeping mulch away from the trunk.

Keep soil consistently moist during the first growing season.

Swamp Tupelo is a hardy, long-lived native tree with high value for ecological restoration, stormwater management, and wildlife habitat. It's a go-to choice for planting in wet, difficult sites where other trees struggle.
