Begonia venosa
Begonia venosa
Also called Felt begonia
Houseplant · BegoniasDO NOT WIPE THE LEAVES — the white felt is the plant's sunshade and its water store, and it does not grow back where a thumb has been. It also wants far more sun and far less water than any other begonia here.

Is it safe for pets and people?
Affects dogs, cats, horses. Signs: vomiting and drooling in dogs and cats; kidney failure in grazing animals. The part below ground is the most toxic.
The whole plant; the underground parts most of all.
Begonias carry soluble oxalates, concentrated in the tubers. That is documented but is not in either catalogue this bank holds — ASPCA answers only about animals, and the RHS harmful list does not carry Begonia at all.
Checked against ASPCA and RHS on 2026-09-21.
