Cosmos 'Rubenza'

As the blooms mature, the petals fade from a deep cranberry to an antique rose with hints of amber. The medium-height plants are very productive, flowering early and continuing to bloom for several weeks if cut or deadheaded. Cosmos are easy to grow, produce a profusion of blooms and are perfect for beginners.

How to Grow:
Indoors (Recommended) - Sow into seedling container 5-7 weeks before last frost, covering seeds lightly. Harden-off and transplant outdoors after last frost. Direct seed - Sow after last frost, once soil temperature is above 16°C, covering seeds lightly. Pinching encourages branching. Tall varieties may benefit from some wind protection.

Harvesting/Vase Life:
Individual blooms don’t last long in the vase, about 4-6 days, but each stem is loaded with multiple blossoms that open over a period of a week. Harvest when flowers are just starting to unfurl, but haven’t fully opened in order to prevent insects from pollinating, which will help stretch the vase life by a few extra days. Flower preservative is recommended.
