Cleome hassleriana (aka Spider Flower): Sweetly fragrant, drought-tolerant annual that is easily grown by direct sowing outdoors, and then self-seeds prolifically to return year after year. Plant cleome in a vegetable garden to attract beneficial insects, and to deter some of the bad bugs that damage crops.
Verbena bonariensis (aka Purpletop Vervain): Fragrant, drought-tolerant, self-seeding, tender perennial for mixed borders, meadows, and cottage gardens. A pollenizer for native bees and butterflies (including swallowtails and monarchs).
Cosmos bipinnatus: Easy-care, pest-free, self-seeding, drought-tolerant, cottage garden annual. Quick to grow by direct sowing outdoors, and the dried seed at the end of the season can be saved for next year. Attracts birds, bees, and butterflies.
Located in the cold frame on the south side of the greenhouse.
