Cosmos bipinnatus 'Sonata Series'

Mexican Aster


Early, compact and very floriferous, this Cosmos bipinnatus Sonata multicolored mix is a superb combination idea that is perfectly suited to borders and containers. Producing masses of 3 inch pure white, soft pink and carmine blossoms (7 cm) with a golden base from early to late summer, this mix looks even more stunning when combined with Mealy-Cup Sage (Salvia farinacea). Beautiful as cut flowers, you will also have the pleasure of enjoying these blooms indoors in a vase!

  • Fairly pest-free and low maintenance, add this charming and graceful plant to the landscape and you will be rewarded with abundant happy butterflies!
  • Growing up to 24" (60 cm) high and 16" (40 cm) across, this is an ideal addition to beds and borders, containers, cottage gardenswild gardens and cutting gardens,
  • Performs best in full sun, in averagemedium moisturewell-drained soilsDry and poor soils are tolerated, but rich, fertile soils should be avoided as the plant may grow taller and flop over. Do not over fertilize as it will promote foliage more than flowers and may also cause the plants to topple. 
  • May be grown from seeds or live plants. Sow seeds outdoors after all danger of frost has passed or indoors 6-8 weeks prior to the last spring frost date.
  • Pinching off dead blossoms will promote continuous blooming. If the flower heads remain, the cosmos will self-seed, but will not become a nuisance.
