Alocasia micholitziana, almost always sold under the cultivar name Frydek, is a velvet-leaf alocasia with deep green, arrow-shaped leaves and prominent white-cream veins. It is more demanding than the Polly hybrid but rewards good conditions with leaves that look like cut velvet. Stable humidity and a sharp-draining mix are the levers that make or break it indoors.

Overview
Alocasia micholitziana was described in the early 1900s and named after plant collector Wilhelm Micholitz. The Frydek cultivar is the form that dominates the houseplant trade and is prized for its velvet texture and crisp venation.
Care Priorities
- Use a sharply draining mix; soggy soil kills it within weeks.
- Bright filtered light keeps vein contrast bold.
- Hold humidity above 60 percent for crispy-edge prevention.
- Wipe leaves gently with a soft damp cloth — leaf-shine sprays damage velvet tissue.
Common Problems
Yellow leaves with soft bases is overwatering. Crispy edges in dry air. Sudden leaf drop with a firm corm is often a temperature shock; keep conditions stable and new leaves usually return.

Frequently asked questions
Frydek vs variegated Frydek — same plant?
Same species, different cultivar. Variegated Frydek has white sectoral patches and grows much more slowly.
How often should I repot?
Every 18 to 24 months, or when the corm fills the pot. Move up only one pot size at a time.
Can I keep it in a bathroom?
Yes, if the bathroom has a window. The naturally higher humidity suits it well.
