Painted Tongue Brings Kaleidoscopes of Color

If you love the magic of kaleidoscopes, you’ll be captivated by the exquisitely patterned flowers of painted tongue.

Painted tongue is related to petunias, and this South American annual bears velvety, trumpet-shaped flowers in jewel tones of yellow, orange, red, pink, purple and bronze. Each flower’s network of veins is often highlighted in a contrasting color, providing a lovely stained glass appearance.

Its form is somewhat open, with many wide-branching stems making it perfect for an informal cottage-style garden where it can mingle with other annuals and perennials. Be sure to plant a few extra for cutting: Stems of painted tongue last up to a week in bouquets.

Garden notes

  • Painted tongue blooms all summer in regions with cool to moderate temperatures; in hot-summer regions, combine it with heat-loving annuals like zinnias that can take over when painted tongue starts flagging.
  • While painted tongue likes cooler temperatures, it’s not frost-tolerant, so don’t plant it outdoors too early.
  • Interplant painted tongue with low, mounding annuals like petunias or sweet alyssum that will hide its leggy stem bases.
  • Compact forms like the Casino Series are good for container plantings.
