Alocasia and Colocasia look strikingly similar, and people mix them up all the time. They're not the same plant, though, and the differences matter when you're deciding which one fits your home.

Alocasia wants bright indirect light and a weekly watering. Colocasia is a bit more laid-back, doing fine in moderate light and tolerating a looser watering schedule. Both are dramatic statement plants, but they suit different spaces.
Alocasia (Alocasia polly) sits in the moderate-to-hard range for care. It needs high humidity, 60% or above, so kitchens and bathrooms often work well. Keep temperatures between 65–75°F and you'll get the best out of it.
Colocasia is a touch easier to manage. It handles moderate humidity without complaint and stays happy in the same 65–75°F temperature range. If you want bold tropical foliage with a little less fuss, this one's worth a look.
The real split comes down to light. Alocasia needs bright indirect light and a weekly watering, while Colocasia is fine with moderate light and a more relaxed schedule.
