Common Names

Little River Canyon Onion

Summary

Little River Canyon onion is a perennial bulbous geophyte native to Alabama and Georgia in the southeastern United States, typically growing on gneiss flat-rocks and sandy Piedmont soils at about 300 m elevation. Bulbs are 1–5+, not rhizomatous; leaves persist green at anthesis, 3+ with blades 10–30 cm long and 1–2 mm wide, and the scape is erect up to 20–30 cm tall; the umbel is erect, compact, 10–15-flowered and hemispheric-globose, with pinkish campanulate flowers; ovary crested, tepals pink, anthers pale yellow, pollen white to pale yellow.

Culture requires full sun and well-drained soil with pH 6.0–7.0; bulbs planted 2–3x height deep and 6–12 inches apart; after planting, thorough watering and soil kept moist but not waterlogged, with reduction during dormancy; apply balanced fertilizer every 4–6 weeks during the growing season. Propagation occurs by seeds that germinate in 2–4 weeks and by bulb division every 3–4 years, with offsets and replanting at the same depth. Uses include ornamental value and edible bulbs and young leaves, plus pollinator attraction and pest deterrence, contributing to garden aesthetics and soil health.
