Butterfly Pentas, Pentas lanceolata
('Butterfly Series')

For a flowering annual to be successful in an Arkansas summer, it must be able to flourish in a hot and humid environment with plenty of bright sunlight. The Butterfly Pentas have proven themselves our match and have consistently rewarded gardeners with vivid displays of red, pink, white and blue flowers all summer long. The tubular flowers are one-half-inch wide stars borne in a dense cluster to as much as three inches across. Pentas flowers are a magnet to butterflies and quickly become one of the most visited plants in the garden. They sometimes are called Egyptian Star Flowers.

  • Height: 24 to 30 inches. 
  • Spread: 12 to 16 inches. 
  • Hardiness: Annual
  • Planting Season: Plant in the spring after the danger of frost is past and the soil temperature has warmed. 
  • Exposure: At least 6 hours of full sun is best. 
  • Culture: Pentas are well suited for the annual flower border, nestled amongst perennials or in containers for patio display. They will tolerate drought, but should receive supplemental watering during dry periods to keep them growing and producing prolific blooms. They require a good supply of nutrition provided by using a slow release fertilizer at planting or by periodic feeding during the summer with a liquid fertilizer.
