Lobelia erinus var. pendula 'Trailing Sapphire' is a cascading lobelia producing abundant intense blue-purple flowers with a graceful, trailing habit — a perfect choice for hanging baskets, window boxes, wall planters, and patio containers. Native to South Africa, Trailing Sapphire is a tender perennial grown as an annual in most climates (hardy in Zones 9–10). Its continuous bloom habit and elegant cascading stems make it one of the most popular trailing flowering plants in cultivation.

Plant Highlights

  • Intense blue-purple flowers with graceful cascading stems to 12+ inches
  • Outstanding in hanging baskets, window boxes, and wall containers
  • Blooms continuously from planting until frost
  • Tender perennial (Zones 9–10); grown as annual everywhere else
  • Tidy, compact growth at the crown with trailing stems below

Growing Guide

Starting indoors (recommended): Sow 10–12 weeks before the last frost. Fill 2-inch pots or cell trays ¾ full with potting soil; mist to moisten. Sprinkle 3–6 seeds per pot on the surface — do not cover; seeds need light to germinate. Cover with plastic wrap and place under a grow light (avoid windows — they fluctuate too much in temperature and light). Check daily; mist if soil dries out.

Germination to transplant: Once shoots are 2–3 inches tall, remove plastic. Harden off over 2 weeks by increasing outdoor time and sun exposure gradually. Transplant after all frost danger has passed. Trailing lobelia excels in hanging pots.

Site and soil: Full sun to partial shade; well-drained, consistently moist soil. Do not allow to dry out completely. Regular watering and occasional feeding will keep plants vigorous all season.
