Growing in Pots, Balconies & Indoors

Ruellia devosiana is a low, tender tropical foliage plant (30-50 cm). The grower rates it as not a houseplant, but it grows well in a pot in a warm, sheltered, part-shaded spot, and a warm, humid, bright windowsill can suit it.

Quick Details

Container Size: A small to medium pot
Indoor Suitability: Not rated as a houseplant; a warm, humid, bright sill may suit it
Best Spot: Full sun to part shade, warm and sheltered
Soil & Drainage: Rich, free-draining mix
Watering in Pots: Keep lightly moist; it likes warmth and humidity

Indoors & On the Windowsill

Not rated indoors: The grower rates it as not a houseplant; if you try it, give it warmth, humidity and a bright spot out of harsh sun.

On a Balcony or Patio

Warm and sheltered: A warm, sheltered, part-shaded balcony or patio suits it; protect it from cold and wind.
Watering: Keep the mix lightly moist and never let it dry out completely.

Choosing the Pot, Soil & Long-Term Care

Pot & drainage: A pot with good drainage holes; do not leave it standing in water.
Potting mix: A light, free-draining mix – a good potting mix, or peat/coir blended with perlite or vermiculite.
Feeding: Container plants use up food faster because watering washes nutrients out – feed a little and often through the growing season.
Long term: Pot on as needed and take cuttings to renew it – it resents cold and prolonged wet.
