Cosmos ‘Rubenza’
Shipping : Mid/Late February 2026
Moody color that deepens and softens all at once.
Cosmos ‘Rubenza’ brings drama to the cutting garden in the most effortless way. Large, single blooms open in a rich ruby red, then slowly mellow into dusty rose and warm terracotta as they age. The shifting color palette means every stem looks a little different, adding depth and movement to both the garden and the vase.
This is an ideal choice for gardeners who want high impact without high effort. Cosmos are famously easy to grow and incredibly productive, and ‘Rubenza’ is no exception. The more you cut, the more it blooms, filling bouquets with long, graceful stems and a painterly range of tones that feel both modern and nostalgic.
Reliable, beginner-friendly, and endlessly useful, this variety solves the need for a bold focal flower that still plays nicely with softer companions.
Because the best flowers change with time.

Start seeds indoors in trays 4 to 6 weeks before last frost, or direct-seed once the weather has warmed. Transplant outdoors only after all danger of frost has passed. Plants establish quickly and thrive with minimal fuss.
Harvesting & Vase Life:
Harvest buds when they are just beginning to crack open but not fully open. For double varieties, allow blooms to open about halfway before cutting. Expect a vase life of approximately 5 to 6 days.
