Haastia pulvinaris, or vegetable sheep, is a species of perennial alpine plant that grows in a bizarre, sheep-like formation on scree slopes in the South Island of New Zealand.

Haastia pulvinaris is a stout, white perennial that grows in thick mats.

The mats can grow up to a few metres in length, and they give the appearance of a flock of sheep from far away.

Another species of Raoulia forms vegetable sheep on the North Island.

The dense wool-like branchlets enable this plant to form tough mats on otherwise inhospitable scree fields.
