About Tiger Paws Begonia
Begonia bowerae 'Tiger Paws' · also called Eyelash Begonia, Tiger Kitten Begonia · houseplant
Tiger Paws is a compact rhizomatous begonia grown for its small, chartreuse-and-chocolate puckered leaves edged in fine white 'eyelash' hairs. It forms a tidy mound from a creeping surface rhizome, thrives in bright indirect light and warm humidity, and stays under 25 cm tall, making it ideal for terrariums, dish gardens, and windowsill collections.
Preferred mix: Light, fast-draining peat- or coir-based mix
Watch for — Crown/rhizome rot: A mushy, blackening rhizome follows overwatering or a buried crown; pot in airy mix, keep the rhizome on the surface, and let the top dry between waterings.
Why tiger paws begonia needs this mix
Tiger Paws Begonia wants a light, fine, evenly moist mix — soft-rooted and crown-sensitive, it suits an airy 1:1:1 blend, not heavy compost.
- Tiger Paws Begonia has fine, shallow roots and a crown that rots if it sits wet, so the mix must be light, airy and only evenly moist.
- Equal parts compost, perlite and vermiculite give steady moisture and plenty of air at once — the balance this plant flowers on.
- A heavy, dense mix smothers the fine roots and is the usual reason it sulks and refuses to bloom.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons tiger paws begonia struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Heavy, water-holding compost rots tiger paws begonia's crown and fine roots — the plant goes limp and mushy at the centre.
- A coarse, gritty cactus-style mix dries too fast and the fine roots desiccate.
- Burying the crown when potting (rather than keeping it just at the surface) causes rot even in a good mix.
Using heavy compost and burying the crown. Tiger Paws Begonia wants a light 1:1:1 mix with the crown sitting right at the surface.
