Cosmos 'Rubenza' Seeds

Cosmos bipinnatus ‘Rubenza’ is a standout half-hardy annual with rich, velvety crimson flowers that soften to warm rose tones as they mature, creating a beautiful two-tone effect. With finely divided, ferny foliage and upright stems reaching around 70–75 cm, it’s ideal for cut-flower beds, borders and containers. Thriving in full sun and well-drained soil, this Cosmos variety flowers reliably through summer and early autumn and is loved by pollinators.
