Zebra alocasia vs Zebra haworthia

Alocasia zebrina · Haworthiopsis attenuata

Pet safety: Zebra haworthia is listed non-toxic to cats and dogs; Zebra alocasia is toxic (insoluble calcium oxalates). If the two are sold under the same name, a mislabelled plant is a genuine risk in a house with animals.

Why these two get mixed up

Both are sold as "zebra plant". That is not a nickname problem — a plant labelled zebra plant in a shop could be either of these, and they want different things.

The differences that matter

Pet safety

This is the difference that matters most. Zebra haworthia is listed non-toxic to cats and dogs; Zebra alocasia is toxic (insoluble calcium oxalates). If the two are sold under the same name, a mislabelled plant is a genuine risk in a house with animals.

Mature size

Zebra alocasia reaches about 36 inches; Zebra haworthia tops out near 8. Buying the wrong one for a shelf means rehoming it in a year.

Watering

Zebra alocasia wants water every 5–10 days, Zebra haworthia every 14–24. On one shared watering schedule, one of them drowns.

Difficulty

Zebra haworthia scores 1 of 5, Zebra alocasia scores 4. the striped stems are why people buy it and they are also why it topples — it needs bright light to keep them short, high humidity to avoid crisping, and it goes dormant if either slips.

Habit

Zebra alocasia grows upright; Zebra haworthia grows rosette. That decides where each one physically works.

Humidity

Zebra alocasia wants a floor of 55%; Zebra haworthia copes at 20%. In a heated room in winter that gap is the difference between crisp edges and none.

Not even related

Zebra alocasia is Araceae, Zebra haworthia is Asphodelaceae. They share a shop label and nothing else — different families, different continents, different care.

Which should you buy?

With a cat or dog in the house, take Zebra haworthia. The other is toxic, and if the shop label is wrong you will not know which you have brought home.
In a dim room, take either — both have a medium light floor.
If you forget to water, take Zebra haworthia, which goes 18 days between drinks.
If it is your first plant, take Zebra haworthia, at 1 of 5.
For a small shelf, take Zebra haworthia, which stops around 8 inches.
