Overview
Browallia is a tender plant grown for its abundant five-petaled, star-shaped flowers in shades of blue, violet, and white. Unlike many flowering annuals, it blooms well in part shade, making it valuable for difficult low-light areas.
Native to tropical South America, it is grown as a warm-season annual outdoors or as a houseplant in cooler climates.
Its mounding to slightly trailing habit and continuous flowering make it ideal for shady borders, hanging baskets, and window boxes.
How to identify it
- Habit: Bushy, mounding to slightly trailing, usually 8-15 in tall.
- Flowers: Star-shaped, five-lobed flowers about 1-2 in across in blue, violet-purple, or white, often with a paler throat.
- Leaves: Soft, oval to lance-shaped, medium-green leaves.
- Bloom: Long flowering season from summer into fall.
- Texture: Slightly fuzzy stems and foliage.
Care & growing
Light: Part shade or bright indirect light; tolerates more shade than most flowering annuals and dislikes harsh midday sun.
Water: Keep soil evenly moist; avoid drying out and waterlogging.
Soil: Rich, well-drained soil or quality potting mix.
Temperature: Warm-season plant sensitive to frost; bring indoors in cold climates.
Feeding: Regular light feeding keeps container plants blooming.
Propagation: From seed started indoors or from cuttings. Pinch young plants to encourage bushiness, and deadhead to prolong bloom.
Habitat & origin
Native to tropical South America, including Colombia, where it grows in warm, partly shaded habitats.
Grown worldwide as a tender annual for shady gardens and containers, and as a flowering houseplant in temperate regions where it cannot survive winter outdoors.
