Cosmos (Cosmos Bipinnatus Sonata Purple) - The Sonata series combines a compact mounded form with massive flowering! Easy to grow, they tolerate heat and dry conditions once established. Cut often for armloads of purple colored blossoms. This container-perfect form of purple cosmos, just like "Dazzler" but one-third the size. You cannot go wrong with this easy to grow and very long-flowering variety. Use it as a front of border filler. Pick or cut it for vases, bouquets, and flower arrangements too.
For the best flower production plant in soils of average fertility with moderate water. Cosmos plants tolerate heat, drought, and poor soils. Remove spent blooms to promote additional flowers. Cosmos will usually self-sow if some spent blossoms are kept on plants. Cut flowers typically last 5 to 9 days when blooms are cut as petals unfold. Flowers fully open in vase. Cosmos attract birds, bees and butterflies.
Directly sow the seeds for this purple flowering Cosmos into prepared seed beds after danger of frost has passed. For a natural setting, the flower seeds can be scattered onto the prepared soil. Lightly rake the soil over the seeds at a depth of 1/16 inch and keep the area moist.
