Cosmos bipinnatus var.

Kneehigh Cosmos

Sonata Cosmos’ compact feathery 2 1/2 to 3 foot plants are soon covered with sprays of buds that open and bloom non-stop all summer long. The blossoms’ 2 inch satiny petals in shades of magenta, clear white, soft pastel pink and pure rose surround cheerful yellow centers. Reliable and long lasting, with stems long enough for cutting lots of bouquets, free blooming Sonatas are perfect for containers, beds or borders. Butterflies and other pollinators love to visit these lovely flowers.

Frost tender.


Sow seeds 1/2 inch deep, 1 to 2 inches apart in a sunny location in well-worked garden soil once danger of frost is past. Keep seed bed evenly moist but not soggy. Seedlings emerge in 5 to 10 days. Keep well weeded and watered while plants are young; mature cosmos can handle hot and dry conditions.


Sow seeds 1 inch apart in a container of seed starting mix, 4 to 6 weeks before last expected frost. Cover 1/4 inch deep, keep moist and provide a good light source. Plant outdoors once weather warms up after gradually acclimating seedlings to outdoor conditions.


Space 6 inches apart when seedlings are large enough to handle.


Carefree cosmos are among the easiest and most reliable of all summer flowers. Plant well-bred kneehigh Sonata for quick bloom and manageable size. The bright silky flowers and ferny foliage combine beautifully with blue salvia, dwarf sunflowers and zinnias. Cutting Sonata’s vibrant flowers for bouquets actually prolongs the blooming season.
