A Striped Jungle Native
The zebra plant, Aphelandra squarrosa, is a tropical evergreen perennial grown for its glossy dark leaves marked with bold white veins. Alongside its foliage it can produce spikes of yellow flowers wrapped in colorful bracts, though coaxing it to bloom takes some patience.

Out of Brazilian Jungle
This plant hails from southern Brazil, where it grows as part of the jungle understory and can behave almost like a climber, reaching up to six feet in the wild. In cultivation it stays far more modest, usually under two feet indoors.

A Demanding Rhythm
Zebra plant wants bright, indirect light and a peat-free, perlite-enriched houseplant compost that stays moist but well drained. Water freely through the growing season and ease off in winter, feeding with a general liquid fertilizer every two weeks in summer and monthly through the colder months. It also craves humidity well above what most rooms offer on their own, so misting, pebble trays, or a humidifier become part of its upkeep.

Cuttings After Flowering
Once flowering finishes, cut the main stem back to a strong pair of leaves to prompt side shoots. When those shoots reach 8 to 10 centimeters, detach and root them as cuttings.

Veined Leaves, Golden Spikes
Its dark green leaves, up to about 30 centimeters long, carry white, silver, or yellow veins running through them, giving rise to the zebra name. Terminal spikes to 20 centimeters bear waxy yellow flowers set against maroon-tinted yellow bracts, appearing sporadically through the year. It grows as a compact, bushy shrub with stout stems, reaching roughly a meter to a meter and a half in height and spread when mature.

Sap-Suckers to Watch
Aphids, scale insects, and mealybugs are the pests most likely to trouble this plant. Whiteflies and fungus gnats can also turn up, with whiteflies leaving yellow speckling on the leaves and fungus gnats favoring moist, peaty soil.

Reading the Leaves
Curling or crinkled leaves usually point to too much light, while wilting or dropping lower leaves can come from soil that is too wet, too dry, or from over-fertilizing. Brown, burned-looking leaf edges are most often the result of excess sun or heavy feeding. Overwatering shows up first as yellowing, translucent leaves, which can progress to a mushy stem and root rot if left unchecked.

Don't Rush the Repot
This plant tolerates being a bit rootbound and doesn't need yearly repotting, flowering contentedly in a pot as small as five or six inches. When repotting is due, do it in spring before the plant leaves winter dormancy, moving up only about an inch in pot size. Dead flower bracts should be removed promptly, since leaving them in place can cause lower leaves to droop and fall.
