A dainty flower with a slender stem, cosmos stand up against heat, drought, and poor soil conditions. Gardeners don’t need to give cosmos much attention after sowing seeds. As long as you deadhead the blooms, avoid overwatering, and stake if necessary, they’ll survive until frost hits the ground in autumn. What’s more, cosmos – which usually have rosy, white, or orange-colored petals– experience relatively few problems with pests, and they also self seed. Available on Amazon; $3.65 for 400 seeds.
