Zebra Plant Care
How Big Does an Aphelandra Plant Get?
Most varieties of Aphelandra are sold when they are about 16” inches tall. Within a couple of years, the height may double. When grown outdoors, these plants grow best in USDA hardiness zones 10 – 11. Zebras are not suitable for colder climates.
When Does The Aphelandra Zebra Bloom?
Aphelandra plants tend to bloom multiple times from late spring and summer months. While you get a nice, long bloom, the interesting pattern on the leaves makes the plant a decorative option for the entire year.
The yellow flowers possess a faint fragrance. They grow in clusters, extending from the two to three-inch spadixes, which are also yellow.
Flower Tip: When flower spikes appear, and until the flowers open, the Aphelandra should receive weekly feedings of a well-balanced, water-soluble houseplant fertilizer.
Once they begin to open, the yellow flowers will last much longer if the plant is moved to a warm, dry location.
The flowers die off a few weeks after blooming, while the yellow spathes remain. After the flowers die, zebra plants become harder to care for.
Aphelandras require high humidity and lots of sunlight but no direct sun. If you want to avoid tossing the plant at the end of the season, pay extra attention to its health throughout the winter.

What Is The Best Soil For Aphelandra Plants?
Sandy potting soil with good drainage is recommended. While the zebra plant needs regular watering during the summer to keep the soil moist. It is susceptible to root rot from excessive watering.
Repot plants in the early spring. When removing the plant, take extra caution with the roots. Gently loosen the soil around the outer edges to help break up the compact soil and loosen the roots.

Prune your Aphelandra back. Remove all weak shoots and cut other shoots back to two buds above the old wood. This will keep the plant compact and bushy.
When new shoots are 2” inches long, turn the plant over and remove the plant from the pot.
Remove any loose soil, shorten all long straggly roots and repot with new soil.
How To Propagate Zebra Plants?
Propagating the plant is a great way to keep it in your collection each year. While these plants tend to die out within two or three years, you can take cuttings to regrow the plant.
Aphelandras are propagated by seeds and stem cuttings.
- Take cuttings from half-ripened wood, or take young growth off with a heel.
- Dust with Rootone and place the cutting ¾”-inch deep in a rooting medium of sand, perlite or vermiculite.
- Bottom heat will root cuttings quickly. Be sure to keep the rooting medium damp.
- After the plant begins to root, plant them in individual pots.
TIP: Cover the planted cuttings with plastic to lock in the moisture and keep them from drying out.
