Lisianthus Excalibur Yellow Seeds

Bold, bright, and ready for floral battle, Excalibur Yellow Lisianthus charges into bouquets with sunny, sword-straight stems and rich, buttery-yellow blooms that bring warmth and cheer to every arrangement. Regal in name and noble in performance, this variety is your go-to hero when you need structure, height, and a splash of sunshine.

Standing tall at 36", Excalibur Yellow flaunts mid-to-large, fully double flowers that look delicate, but don’t be fooled. These blooms are backed by sturdy stems and a resilient nature, making them ideal for cutting, arranging, and dazzling in the vase.

Growing from seed? It’s a quest worth the patience. Use a fine, well-draining mix and sow those tiny, pelleted seeds gently on the soil’s surface as they need light to awaken! Keep seedlings cool to encourage strong roots, transplant 4–6 weeks before your last frost, and let your flower knight brave the chill. Once established, this variety takes on summer heat and dry spells like a champ.

- Bright, sunny double blooms that light up arrangements
