Care

Light

Provide bright indirect light to preserve compact growth and strong leaf color. Introduce direct sun gradually.

Water

Water thoroughly when the upper inch of mix begins to dry, then drain completely. Reduce watering during slow winter growth.

Standard soil mix

Use two parts screened potting mix, one part fine bark, and one part perlite. Use a container with an open drainage hole.

Flowering

Small three-petaled pink, purple, or white flowers may appear under bright light. Flower color and form depend on the species or cultivar.

Propagation

Take a clean stem cutting with at least one node. Root the node in water or a lightly moist, airy mix. Several cuttings together produce a fuller pot.

Commonly cultivated inch plants come from warm parts of the Americas, where trailing stems spread across moist ground or vegetation in filtered light. Reproduce the useful functions—warmth, bright filtered light, drainage, and moderate moisture—without releasing discarded stems outdoors.
