This description was machine-translated.
Description
The Yellow Cosmos blooms from July until frost in fiery yellow and orange, adding airy lightness to the garden with its delicate foliage. This annual plant is heat- and drought-tolerant and attracts butterflies and wild bees, making it ideal for naturalistic summer beds.
Care instructions
Sow the Yellow Cosmos in the garden from April or transplant seedlings from late April, planting after the last frost (mid‑May). Choose a full‑sun, somewhat sparse site, on rich soil it produces more foliage and fewer flowers. Water sparingly and remove spent blooms to encourage continuous flowering until the first frost.
