Triteleia laxa (Ithuriels Spears)

Reminiscent of a spear, Triteleia laxa (Ithuriel's Spear) is a late spring or early summer flowering corm featuring funnel-shaped flowers, up to 1-2 in. wide (2-5 cm), arranged in large, loose umbels rising on long, slender stalks atop narrow, erect basal leaves. The flower color varies from deep blue to pale purple-blue to almost white. Since they open up one at a time, the blooming period of this flower bulb lasts for quite a while before it goes dormant, requiring a summer dry rest. Easy to grow, undemanding, beautiful and adaptable, this plant is a great addition to the landscape.

  • Growing up to 15-18 in. high (37-45 cm), this beauty will naturalize in optimum growing conditions and will come back year after year!
  • Easily grown in light, sandy, fertile, well-drained soils in full sun or part shade. Tolerates clay soil. In cold winter areas, apply a layer of mulch to protect this plant. For best results, provide the plant with consistent moisture spring to early summer; however, maintain a dry soil after blooming until the following spring. Drought tolerant.
  • Virtually disease-free and pest-free.
  • Stunning in beds, borders, rock gardens, cottage gardens or city gardens. For best visual impact, plant in groups (at least 10 bulbs). Long-lasting cut flowers with a great vase life.
  • Propagate by separating corms when dormant.
