Cosmos Asteraceae
FLOWER-COSMOS-BICOLOUR MIX This typical cosmos stands out with its large, two-toned daisies of white to pale pink edged in rich raspberry red. Grows fast from seed. The tall, many-branched stems are lined with feathery, very finely divided, and light to medium green foliage. An abundance of large, bowl-shaped daisies top the stems throughout the summer. Cosmos are heat-loving plants which grow best in full sun and moist to somewhat dry, well-drained soil of average fertility. Remove faded blossoms regularly for best flowering and performance.

Sow thinly 5mm deep in growing position or in punnets or seed boxes of moist seed compost, or plant directly in the garden.
