About Twinflower
Twinflower (Dyschoriste oblongifolia) is a native Florida groundcover perennial with oblong leaves and paired lavender-purple trumpet flowers that bloom from spring through fall, with heaviest bloom in May. It spreads by underground runners and self-seeds to form a soft, low mat and is a larval host for the Common Buckeye butterfly — an ideal low-care groundcover for sunny, sandy NE Florida gardens. Starting at $7.95.

Care essentials
Light
Performs well in full sun to part shade in NE Florida; full sun produces the densest groundcover while partial shade yields open, spreading growth. An ideal low-maintenance native groundcover for sunny to lightly shaded sandy areas.
Water
Drought-tolerant once established in NE Florida's sandy soils; water during the establishment period and during extended summer droughts. Avoid consistently wet or waterlogged conditions — this native groundcover prefers well-drained sites and will thin out if roots stay saturated.
Soil & Fertilizer
Thrives in NE Florida's acidic, sandy, well-drained soils with minimal fertility; no regular fertilization needed. Avoid heavy mulching or amended soils, which can reduce spread. Space plants 24–36 inches apart and allow underground runners to fill in naturally.
