Taxonomy ID: 7530

Triantha racemosa is a small perennial in the Tofieldiaceae family. Common names include coastal false asphodel and savanna asphodel. An older name is Tofieldia racemosa. Its native range runs from New Jersey to Texas. It grows in coastal parts of the eastern and central United States. Wild plants occur in pine barrens, savannas, and seepage bogs. They also grow where savannas meet pocosin wetlands.

The plant grows upright and looks like grass between blooms. Narrow green leaves form a rosette at its base. This leaf cluster reaches about 1 foot [0.30 metres] tall. Each leaf is simple, with smooth edges and a sticky feel. Leaves exceed 0.5 feet [0.15 metres] in length. They stay under 0.08 feet [0.025 metres] wide. The flowering scape reaches about 1.25 feet [0.38 metres]. It feels rough and sticky, and lacks any scent. It may lack leaves or bear one to three near its base.

Small, star-shaped flowers crowd the upper part of the scape. The flower-bearing section spans about 0.25 feet [0.08 metres]. Flowers grow in small groups along this crowded raceme. Each bloom has six white tepals and six stamens. Individual flowers measure less than 0.08 feet [0.025 metres] across. In North Carolina, flowering runs from June through August. The flowers turn orange as they dry. Fruits follow as capsules, with at least two seeds each. North Carolina plants bear fruit from September through October. The fruit display may include blue and red-burgundy shades.

Grow this species in full sun and moist, sandy soil. It needs at least six hours of direct sun daily. It also tolerates soil that becomes wet at times. The source lists neutral soil and notes a preference for lime. USDA hardiness zones 7a through 9b suit its cultivation. It tolerates heat and grows at a moderate rate. Its listed upkeep needs are moderate. Seed is the recommended way to raise new plants.

This small native suits borders, naturalized areas, and native gardens. It can also grow in groups in coastal landscapes. Its flowers provide summer interest, while capsules add a fall display. The grass-like leaves give it a different look outside bloom.
