African Violet and Alocasia Polly both like bright indirect light, which can make the comparison tricky. But the similarities mostly stop there. One is a compact bloomer; the other is a bold, dark-leafed statement plant with a reputation for being a little temperamental.

African Violet (Streptocarpus ionanthus) prefers bright indirect light and weekly watering. Alocasia Polly (Alocasia × amazonica 'Polly') wants the same light but goes seven to ten days between waterings. They share a light preference, but their care needs — and their personalities — diverge from there.
African Violet is a low-maintenance bloomer that earns its place on any windowsill. Water it weekly, give it consistent bright indirect light, and it'll flower for months. It's forgiving of the odd missed watering, and its compact size makes it easy to fit anywhere.
Alocasia Polly is more demanding. It wants high humidity, consistent warmth, and bright indirect light — and it'll drop leaves dramatically if any of those slip. The payoff is stunning dark green leaves with bold white veining that look like they belong in a botanical illustration.
Both plants need bright indirect light. African Violet is the more forgiving of the two; it tolerates normal home humidity and recovers from inconsistency. Alocasia Polly can go dormant or shed leaves if it's unhappy, which catches new growers off guard. Watering is the other key difference: weekly for African Violet, every seven to ten days for Polly.
If you want reliable, low-drama blooms, African Violet wins. If you're comfortable with a moodier plant and want dramatic foliage as the payoff, Alocasia Polly is worth the effort.
African Violet and Alocasia Polly occupy the same light bracket but different care leagues. The violet is approachable and rewarding for most people; the Polly is a bit more of a commitment, but the foliage makes it worth it for the right grower.
African Violet is easier for most growers. Alocasia Polly is more demanding about humidity and hates drafts or sudden temperature changes.
Neither does well in low light. Both need bright indirect light to stay healthy and retain their color.
African Violet: once a week. Alocasia Polly: every seven to ten days. Let the top inch of soil dry out before watering either plant.
Go with African Violet for ease and flowers. Go with Alocasia Polly if you want bold architectural foliage and can keep up with its humidity needs.
