I believe cosmos to be a "must have" for every garden. They are a beautiful flower.... now with so many fun varieties .... and so easy to grow! Simply scatter seeds in the garden and they will grow like mad!Best grown in poor soil; rich feeding leads to very big branches with poor flowering which tend to be floppy. Deadheading prolongs flowering.The plant height varies from 2–4 ft (0.61–1.2 m). The cultivated varieties appear in shades of pink and purple as well as white. Its foliage is finely cut into threadlike segments. When flowering, the plant can become top heavy. This problem is alleviated when grown in groups, as the bipinnate leaves interlock, and the colony supports itself.
