About Begonia 'Tiger Paws'
Begonia bowerae 'Tiger Paws' · also called tiger paws begonia, eyelash tiger paws · houseplant
Begonia 'Tiger Paws' is a compact eyelash begonia derived from Begonia bowerae, with small, lime-green leaves boldly marked in chocolate-brown tiger-stripe patterning and fringed by fine white 'eyelash' hairs along the margins. It forms a tidy rhizomatous mound and sends up airy pink flowers. Easy and forgiving, it suits windowsills, terrariums, and small pots.
Preferred mix: Light, airy, free-draining mix
Watch for — Rhizome rot: Overwatering or burying the rhizome causes soft, mushy rot. Keep the rhizome on the surface and let the mix dry between waterings.

- A heavy, dense mix smothers the fine roots and is the usual reason it sulks and refuses to bloom.
