Rubenza Cosmos: Deep, Dramatic Hues for a Bold Garden Statement

Rubenza Cosmos is a captivating variety cherished for its intense, jewel-toned blooms. These unique cosmos flowers emerge in deep burgundy and ruby shades, gradually softening to a rich rose hue as they mature. Standing up to 4 feet tall, Rubenza Cosmos has slender stems adorned with feathery green foliage that beautifully complements its striking blooms.

The large, single-petaled flowers of Rubenza Cosmos bring bold color to the garden from summer through fall, especially with regular deadheading to extend the flowering season. Perfect for cutting gardens, mixed borders, and adding depth to floral arrangements, Rubenza Cosmos offers an eye-catching, moody elegance unlike any other cosmos variety.

Sow directly after the last frost, or start indoors 4-6 weeks before transplanting. Regular deadheading encourages more blooms, ensuring that Rubenza Cosmos fills your garden with its warm, velvety hues all season long.
