COMMENTS: Sweet Williams are well-known cottage garden plants cultivated since the 16th Century in England. The blooms are dense, flat-topped clusters of varicolored flowers. It is a biennial* in very cold zones and a perennial in warmer zones. If allowed to set seed, clusters of new plants often form around the old stalk. A well-drained, humusy soil should keep it happy. This close relative of the carnation is a wildflower taken directly into gardens from the wild. There are now hundreds of hybrids made from this flower and others in the ‘pink’ family. The flowers last long in the vase. It dislikes humidity. Suggested cultivars:
