Of all the annual plants you can grow in your cutting garden, none are more productive per square foot than cosmos. The more you cut, the more they bloom. If you want a perfect pure white, single flowered variety, then look no further. This cheerful daisy-like bloomer is an excellent choice.
Plant type: annual
Site: full sun
Days to maturity: 75-90 days
Plant spacing: 12”
Pinch: when 12” tall
Approx seeds per packet: 50
How to Grow:
Start seed indoors in trays 4-6 weeks before last frost; transplant out after all danger of frost has passed. Cosmos can also be direct seeded once weather has warmed.
Individual blooms don’t last long in the vase, about 4-6 days, but each stem is loaded with multiple blossoms that open over a period of a week. Harvest when buds are cracking, but haven’t fully opened in order to prevent insects from pollinating, which will help stretch the vase life by a few extra days. Flower preservative is recommended.
