Blue-Flowered Torch

bright indirect light (3-6 feet from a south or west window, or right next to an east window. Under a grow light, 6-10 inches away works well). It tolerates no direct sun (right in the window where sun actually hits the leaves. A strong grow light 4-6 inches away can substitute) well - hot direct rays bleach the leaves and leave pale brown patches. A bright spot a few feet from a south or west window works well.

Prefers 60-70% relative humidity. Brown leaf tips are a reliable sign the air is too dry. A pebble tray, grouping with other plants, or a humidifier all help.

If potted rather than mounted, use a very open, fast-draining mix such as orchid bark or a blend of coarse perlite and peat. The roots are primarily anchors, not feeders.

Susceptible to Fusarium rot if water sits in the base, and to scale insects and mealybugs. Pale, bleached patches indicate too much direct sun. Dark, soft, or drooping leaves usually mean insufficient light.
