Cosmos ‘Rubenza’
ETA: Shipping begins Mid February
Moody, romantic, and full of depth.
Cosmos ‘Rubenza’ is a dramatic standout in the cutting garden, offering a rich, evolving colour story that feels both bold and earthy. Large, single blooms open in a saturated ruby red, then slowly soften into shades of muddy rose and warm terracotta as they mature. The shifting tones give each stem a layered, painterly quality that makes arrangements feel thoughtful and expressive.
Easy to grow and wonderfully prolific, this variety produces armfuls of blooms over a long season. It’s an ideal choice for beginners who want high impact without complication, and for seasoned growers who love flowers that bring warmth and mood to their work.
Because the most beautiful colours are rarely static.
