Boea is a genus of plants in the Gesneriaceae (Gesneriads) family, with species originating from Australia, China, India, Malaysia, Birma, Philippines, Polynesia, Solomon Islands, Thailand, Papua New Guinea, Indonesia, Nepal, Bhutan, Cambodia, Vietnam and Laos . Boea make good house plants (see main image), but also successfully grow in the wild.

For example, Boea 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 altitudide range from 60-900 metres. It grows along creek beds, on moist banks, moss-covered rocks in rainforest, open forest, vine forest and gallery forest.

Some Boea species are known as types of resurrection plant due to their ability to survive dessication (e.g. Boea hygrometrica and Boea hygroscopica) .

Cultivation

These cultivation notes are based on Boea hygroscopica, a species from Northern Queensland, Australia

Boea hygroscopica grows to about 15cm (~6 inches), and forms a dense, velvety clump that flowers over many weeks in the warm months.

Suggested soil for this plant is:

• Potting mix with 20% sand mixed in
• 5mm (~0.2 inches) of scoria or other drainage material in the bottom of the pot
• Fertiliser with an [[NPK] ratio of about 13.8:3.2:9.9, plus trace elements.

This plant prefers bright, filtered like, possibly with some early-morning direct sun. Pot on as needed. 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.
