Opuntia microdasys

This article is about a plant colloquially known as bunny ears. For other uses, see Bunny ears (disambiguation).

Opuntia microdasys (angel's-wings, bunny ears cactus, bunny cactus or polka-dot cactus) is a species of flowering plant in the cactus family Cactaceae, native and endemic to central and northern Mexico.

Opuntia microdasys forms a dense shrub 40–60 cm tall, occasionally more, composed of pad-like stems 6–15 cm long and 4–12 cm broad.

Instead of spines it has numerous white or yellow glochids 2–3 mm long in dense clusters. They are barbed and thinner than the finest human hairs, detaching in large numbers upon the slightest touch. If not removed they will cause considerable skin irritation so the plants must be treated with caution.

The Latin specific epithet microdasys means “small and hairy”.

The yellow flowers appear only rarely. Despite this, it is a very popular cactus in cultivation, partly because of the young plant’s comical resemblance to a rabbit’s head. It has gained the Royal Horticultural Society’s Award of Garden Merit.
