Heart Attack Sweet William, Sweet William
This entry has yet to be reviewed and approved by L2G editors.
While most cultivars of Sweet William are biennials, 'Heart Attack' performs as a perennial if sheared after flowering, or as a biennial if allowed to self-seed. The plant grows in a thick mat of wiry stems and lance-shaped leaves. In late spring the familiar carnation flowers in flat clusters cover the plant. The flower color is an unusual reddish-black. The species is native to southern Europe.
For best growth and flowering, 'Heart Attack' needs well-drained soil rich in organic matter and full sun. On soils that drain slowly or shady locations where the plant takes a long time to drain after rain or watering, it is susceptible to blight and rot. Full sun is the remedy. As the first flush of flowering fades, shear the plant to encourage new growth and perenniality.
