Chabauds Giant Carnation is a half-hardy biennial prized for its long bloom season. Large flowers with lovely spicy, clove-like fragrance bloom in many shades of crimson, red, rose, pink, yellow, and white. Carnations grown in groups make a striking attraction in gardens. For early blooms, start indoors 6-8 weeks before the last frost. Thin or transplant when 15-25 cm tall. This tender perennial can overwinter in milder climates. To overwinter in Zone 3b to 4a cover with a thick layer of mulch but remove mulch in early spring.
One of the garden favourites-Chabauds Giant Carnation does not readily self-sow. Harvest early spent blossom head by cutting stem near the ground and hang dry with a paper bag tied around the stem to catch seeds that may drop.
