Boea is a genus of plants in the family Gesneriaceae, with species originating from Australia, China, India, Malaysia, Myanmar, Philippines, Polynesia, Solomon Islands, Thailand, Papua New Guinea, Indonesia, Nepal, Bhutan, Cambodia, Vietnam and Laos. [1]
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]
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.
The Smithsonian lists the following Boea species. [1]

A resurrection plant is any poikilohydric plant that can survive extreme dehydration, even over months or years.
Melastoma affine, also known by the common names blue tongue or native lassiandra, is a shrub of the family Melastomataceae. Distributed in tropical and sub-tropical forests of India, South-east Asia and Australia, it is a plant of rainforest margins. Bees are the principal pollinators of this species.
Alloxylon flammeum, commonly known as the Queensland tree waratah or red silky oak, is a medium-sized tree of the family Proteaceae found in the Queensland tropical rain forests of northeastern Australia. It has shiny green elliptical leaves up to 18 cm (7.1 in) long, and prominent orange-red inflorescences that appear from August to October, followed by rectangular woody seed pods that ripen in February and March. Juvenile plants have large deeply lobed pinnate leaves. Previously known as Oreocallis wickhamii, the initial specimen turned out to be a different species to the one cultivated and hence a new scientific name was required. Described formally by Peter Weston and Mike Crisp in 1991, A. flammeum was designated the type species of the genus Alloxylon. This genus contains the four species previously classified in Oreocallis that are found in Australasia.
Livistona australis, the cabbage-tree palm, is an Australian plant species in the family Arecaceae. It is a tall, slender palm growing up to about 25 m in height and 0.35 m diameter. It is crowned with dark, glossy green leaves on petioles 2 m long. It has leaves plaited like a fan; the cabbage of these is small but sweet. In summer it bears flower spikes with sprigs of cream-white flowers. The trees accumulate dead fronds or leaves, which when the plant is in cultivation are often removed by an arborist.
Hibbertia dentata, commonly known as toothed guinea flower, trailing guinea flower or twining guinea flower, is an ornamental plant in the family Dilleniaceae native to the east coast of Australia. Found in woodland, it is a trailing or twining vine with leaves with several small 'teeth' on the margins and bright yellow flowers in early spring. It adapts readily to cultivation and can be grown as a pot plant. The species was first described in 1817.
Buckinghamia is a genus of only two known species of trees, belonging to the plant family Proteaceae. They are endemic to the rainforests of the wet tropics region of north eastern Queensland, Australia. The ivory curl flower, B. celsissima, is the well known, popular and widely cultivated species in gardens and parks, in eastern and southern mainland Australia, and additionally as street trees north from about Brisbane. The second species, B. ferruginiflora, was only recently described in 1988.
Dendrobium speciosum, commonly known as the rock orchid or cane orchid, is a species of highly variable Australian orchid. Its varieties can be found in a range of habitats as epiphytes or lithophytes. It has a continuous distribution along the east coast of Australia and in distinct populations along the Tropic of Capricorn. As a lithophyte, it forms gigantic spreading colonies on rocks and cliff faces, often exposed to full sun, with its roots forming dense, matted beds across the rock that anchor the plant. It can be found at altitudes from sea level to 900 metres (3,000 ft).
Commelina cyanea, commonly known as scurvy weed, is a perennial prostrate herb of the family Commelinaceae native to moist forests and woodlands of eastern Australia, Lord Howe Island and Norfolk Island. The blue flowers appear over the warmer months and are pollinated by bees and flies.
Pterostylis nutans, commonly known as the nodding greenhood or the parrot's beak orchid, is a species of orchid endemic to eastern Australia. Nodding greenhoods have flowers which "nod" or lean forwards strongly, have a deeply notched sinus and a curved, hairy labellum.
Anopterus glandulosus, commonly known as native laurel or Tasmanian laurel, is a species of shrub or small tree in the family Escalloniaceae. Endemic to south and southwestern Tasmania, A. glandulosus is widespread in the moist understoreys of Tasmanian temperate rainforests and wet sclerophyll forests from sea level to mountainous regions below 1,200 metres (3,937 ft) above sea level.
Xanthostemon chrysanthus, the golden penda or first love, is a species of tree in the myrtle family Myrtaceae, endemic to north eastern Queensland, Australia. It is a popular garden plant with showy yellow blooms.
Cordyline petiolaris, known as the broad leaved palm lily is an evergreen Australian plant. A shrub to around 5 metres tall. Found in warm rainforest and moist eucalyptus forest. The range of natural distribution is from the Nambucca River to near Gladstone, Queensland.
Cordyline rubra, known as the palm lily is an evergreen Australian plant. It grows as a shrub to around 4 metres (13 ft) tall. Found in warm rainforest and moist eucalyptus forest. The range of natural distribution is from Lismore to near Bundaberg, Queensland.
Myoporum acuminatum, commonly known as waterbush, pointed boobialla or mangrove boobialla, is a flowering plant in the figwort family Scrophulariaceae and is endemic to eastern Australia. It grows in rainforest or wet eucalyptus forest near the coast and in the Coastal Ranges, and is occasionally associated with mangroves. Occasionally it is found in the drier rainforests. It grows naturally as far south as Mimosa Rocks National Park in far south eastern New South Wales, and north to Fraser Island in Southern Queensland.
Pouteria eerwah is a rare species of Australian rainforest tree in the family Sapotaceae. Common names include shiny-leaved condoo, black plum and wild apple. It is endemic to south eastern Queensland, with a restricted distribution and regarded as endangered. There is discussion whether this plant should remain named as Planchonella eerwah.
Nematolepis squamea , commonly known as Satinwood, is an upright shrub or small tree species which is endemic to Australia.
Dysoxylum parasiticum, known as yellow mahogany, is a species of rainforest trees in the family Meliaceae. The specific epithet parasiticum is from the Latin meaning "parasitic", referring to the idea that the flowers are parasitic on another tree species.
Clematis glycinoides, commonly known as headache vine, is a climbing shrub of the family Ranunculaceae, found in eastern Australia, and New Caledonia.
Lomandra multiflora is a perennial, rhizomatous herb found in Australia. Lomandra multiflora is also commonly known as many-flowered mat rush, mat rush and many flowered mat-lily. Lomandra multiflora is a species that is native to Australia and can be found in New South Wales, Queensland, Victoria, South Australia, Northern Territory of Australia and also in Papua New Guinea. The mat rush is distributed widely in the region and common within its preferred growing conditions. The conservation status of Lomandra multiflora is considered not to be of concern and risk.
Boea hygroscopica is one of 15 species of flowering plant of the Boea genus in the gesneriad family. It is considered a 'resurrection plant' because of its ability to withstand virtually total water loss. Detached leaves of B. hydroscopica can withstand desiccation by increasing the small amount of constitutive glutathione by up to 50 times.
