For example, B. hygroscopica, also known as the Queensland rock violet in Australia, occurs in Cape York Peninsula and Northeast Queensland as far south as Rockhampton, within an altitude range from 60–900 metres (200–2,950 ft). It grows along creek beds, on moist banks, moss-covered rocks in rainforest, open forest, vine forest and gallery forest.[2]
Some Boea species are known as types of resurrection plant due to their ability to survive desiccation (e.g. B. hygrometrica and B. hygroscopica).[3][4]

Cultivation
These cultivation notes are based on B. hygroscopica, a species from Northern Queensland, Australia.[5]
B. hygroscopica grows to about 15 centimetres (6 in), and forms a dense, velvety clump that flowers over many weeks in the warm months.
A well-drained soil is suggested for this plant, achieved by using a potting mix with 20% sand content, and 5mm (~0.2 inches) of scoria or other drainage material in the bottom of the pot. A fertilizer with an NPK ratio of about 13.8:3.2:9.9, plus trace elements, is recommended.
This plant prefers bright, filtered light, possibly with some early-morning direct sun. It can be planted in the garden in a well-drained, consistently moist location.
The only major pests of this plant are chewing insects such as grasshoppers and caterpillars.
