Cosmos bipinnatus 'Double Click Cranberries'
This selection from the Double Click Series bears double to semi‑double flowers in deep cranberry red. It stands out for fuller, ruffled petals that give a more formal look than single types. It performs best in full sun and well‑drained garden soil. Plants flower from summer to frost in most regions. Stems are long enough for bouquets with a lighter, airy feel. Treat it as a frost‑tender annual.
