Isotoma hypocrateriformis, commonly known as Woodbridge poison, is a small herbaceous perennial in the family Campanulaceae native to Western Australia.[1] It is found in a variety of habitats in the South West, Wheatbelt and Great Southern regions of Western Australia where it grows in sandy soils around granite.[1]

The erect, succulent and annual plant typically grows to a height of 0.08 to 0.6 metres (0.3 to 2.0 ft). It blooms between September and January producing white-blue-purple-pink flowers. Flowers are about 2.5 cm in length.

I. hypocrateriformis is known as Woodbridge poison because it resembled a toxic European plant to early settlers.[2]
