Nyssa sylvatica var. biflora, commonly known as Swamp Blackgum or Swamp Tupelo, is a striking ornamental tree that thrives in parks and extensive gardens, often serving as a majestic specimen or shade tree. With its initial youthful pyramidal form, it evolves into a distinguished, spreading silhouette with age. This unique variety is specially adapted to thrive in heavy organic or clay soils of wet bottomlands, making it a perfect choice for those challenging environments. Its foliage varies in shape—oval, elliptical, or obovate—and spans 5-12 cm long. These leaves transform from a glossy green into a vivid purple in autumn and finally radiate a brilliant scarlet hue.

The tree’s small, greenish-white clustered flowers are vital for honey production, while its fruit serves as an important food source for birds. Durable and cross-grained, its tough wood has historical significance in crafting various tools and structures. As the longest-living non-clonal flowering plant in Eastern North America, capable of reaching ages over 650 years, Swamp Blackgum continues to be a beacon of biodiversity and resilience. Whether for its ecological importance or ornamental appeal, Nyssa sylvatica var. biflora is an outstanding choice for any landscape.
