Choose Seeds for Your Outdoor Cutting Garden
Which one should I choose?
For a direct-sown summer option, choose Double Click Mix cosmos for fuller mixed-color blooms or Cupcakes White for cupped white flowers. For rose-like focal flowers that need an early indoor start and extra care, choose Arosa 1 Lilac or Croma 3 Pink Picotee lisianthus. For vertical bouquet lines, choose Avignon 2 Rose or Madame Butterfly Bronze White snapdragons.
The featured snapdragons are alternatives to the Legend series discussed later, not Legend varieties. Avignon 2 Rose is a cool-season cutting selection. No greenhouse does not mean every variety has the same sowing schedule: follow the individual listing and plan your indoor starts, hardening off, and outdoor season accordingly.
Double Click Mix grows around 48 inches tall, Cupcakes White 36–46 inches, Avignon 2 Rose and Croma 3 Pink Picotee 31–39 inches, Madame Butterfly Bronze White 26–36 inches, and Arosa 1 Lilac 16–24 inches. These cards spotlight three of the guide’s flower types; the zinnia, statice, and strawflower shopping links remain below.

🌸 1. Lisianthus
Lisianthus are famous for their rose-like blooms and exceptional vase life. They perform beautifully in outdoor beds when started early and hardened off properly. Sow seeds indoors 10–12 weeks before your last frost, then transplant once nights stay above 50°F.
