Madagascar periwinkle grows to 1–2 ft. tall and comes in mounding and trailing forms. It excels at producing summer-to-fall color in hot climates, and keeps flowering through Thanksgiving if weather stays mild. Glossy green, 1–3-in.-long leaves cover a bushy plant 1–2 ft. tall and wide; 1 1/2-in. flowers come in white, white with a rose or red eye, apricot, cherry, pink, and bright rose. Lives over, if a bit ragged, in frost-free areas. In desert regions, may also look poor in late summer. Self-sows. Provide good drainage and avoid overwatering.
The Cora series has mounding and trailing forms, many colors, and extra-long bloom; grows 14–16 in. tall. Pacifica and Cooler series are compact 15-in. plants with 2-in. flowers.
The Mediterranean series, featuring apricot, pink, rose, lilac, or white blooms, grows 5–6 in. high and can spread 2 1/2 ft. wide.
All types bloom the first season from seed sown early indoors or in a greenhouse or cold frame. The Tropicana series blooms in only 60 days from seed and bears blooms in shades of pink and coral on 1-ft. plants.
