Still plenty of planting time! See chart below.
These beauties germinate in as little as 3 -6 days!
Let’s face it, Cosmos are happy flowers! Not particular where the party is or who else is invited, Cosmos are just happy to be there and will improve any setting once invited. Simply direct-sow Cosmos seeds in your bed, border or meadow and let their sunny disposition, waving to and fro in the wind, brighten your day.
At the optimal temperature of 75 degrees, Cosmos flowers will present themselves just 50-60 days later. Once in bloom, cosmos height varies from 2-4 feet tall and can become top-heavy. Avoid this problem by planting in groups, or as a thick border along a fence line. The leaves will interlock, the colony will support itself, and you will reap the benefits of their show. Happy!
