    Appearance: Perennial herb with short, stout stem nearly hidden by overlapping leaf bases. Forms clumps by offshoots from fleshy rootstock.

    Leaves: Spreading-erect, closely overlapping in spiral pattern. Blades broadly linear, sharp-tipped, waxy, stiff, somewhat fleshy, 15–30 cm (6–12 in) long and 2.5–8 cm (1–3 in) wide; upper surfaces dark green or green with pale yellow stripes; lower surfaces usually purple.

    Flowers: Small, white, clustered within a folded, boat-shaped bract (spathe) 3–4 cm long, short-stalked from leaf axils. Three petals, 6 stamens with hairy stalks.
    Fruit: A 2-seeded capsule, in clusters within the bract.

    Ecological threat: Forms dense ground cover and clumps quickly. Has escaped into coastal tropical hammocks, where the dense cover pre-vents seedling growth of native canopy tree species. FLEPPC Category I

    Distribution: SW, SE

    Tradescantia spathacea (syn. Rhoeo spathacea) is rarely found growing in the disturbed sites of Lee, Broward, Miami-Dade and Monroe counties. It is native to tropical America but escaped from cultivation. Oyster plant blooms all year.
