Agrostemma githago. Easily grown, it should be direct-sown after all danger of spring frost has passed. Corn Cockles may also be started indoors 4 weeks before transplanting out after the threat of spring frost has passed. Use individual peat pots or seed-starting cells to avoid root disturbance. Provide even moisture, strong light and air circulation. Prepare a bed in full sunlight with loamy, well-draining soil. Harden off the seedlings by gradually acclimating them outside for a week to 10 days before transplanting out. Thin or transplant to 12" apart. Keep the bed well-weeded and moderately watered until the plants are established. A British cottage garden favorite, it yields abundant 5-petaled, 11⁄2" fuchsia-pink flowers with black-whiskered white centers on fine-haired stems. Summer flowering. Height: 2' to 3'.
