Frilly pinkish-blushed blooms frolic atop this whimsical cosmos. As the summer progresses, these dwarf charmers prolifically produce candy striped and snow capped semi-double flowers with abundant glee that rise above bushy bundles of feathery foliage. A long seasonal, easy to grow annual, ‘Cosimo Collarette’ continues to lift spirits well into autumn with staunch cut-flower potential.
How to care for Cosmos bipinnatus Cosimo Collarette (Cosimo Series):
Easy to grow, Cosmos enjoy reliably moist soil but be careful not to overwater. Pinch out young tips for a bushier plant. Deadhead spent flowers regularly to stimulate further blooms. May require staking with peas sticks or brash in exposed locations.
Sowing instructions:
In early spring, sow seed shallowly in seed trays and keep under glass, transplanting them into individual pots when large enough to handle. Harden off before planting outside after the frosts. Alternatively, sow in-situ in mid- to late spring in a well-prepared bed and thin the seedlings out as they grow to allow approximately 30cm between each.
