Rhus — 15 species
Botanical species in the genus Rhus recorded in the PlantPeers database.
Rhus aromatica
Rhus aromatica
Family: Anacardiaceae
Cultivation
Rhus aromatica is a very cold-hardy plant, able to tolerate temperatures down to around -25 to -35°c when fully dormant. The young growth in spring, however, is much more tender and can be damaged by late frosts. Succeeds in a well-drained fertile soil in full sun and in partial shade.

Rhus chinensis
Rhus chinensis
Family: Anacardiaceae
Cultivation
Rhus chinensis is a plant of the warm temperate to tropical zones, found at elevations of 900 metres or more in Indonesia. It only has moderate cold-hardiness, tolerating short periods with temperatures down to around -8°c when it is fully dormant. Young growth in spring is more sensitive to cold, and can be damaged even by light frosts.

Rhus copallinum
Family: Anacardiaceae
Cultivation
Rhus copallinum is a very cold-hardy species, when fully dormant it can tolerate temperatures down to about -25°c. However, the young growth in spring is much more tender and can be damaged by late frosts. Plants grow best in areas with hot summers.
Full cultivation guide →Rhus coriaria
Rhus coriaria
Family: Anacardiaceae
Cultivation
Rhus coriaria is not very cold-hardy, tolerating short-lived temperatures down to around -5°c when it is fully dormant, and is unlikely to succeed outdoors in any but the mildest parts of the temperate zone. Another report says that the plant is quite hardy and is often grown in British gardens. The young growth in spring is more tender, and can be damaged by late frosts.

Rhus glabra
Family: Anacardiaceae
Cultivation
Rhus glabra is a very cold-hardy plant, when fully dormant it can tolerate temperatures down to at least -25°c, especially if the wood has been fully ripened by a hot summer. However, the young growth in spring is more tender and can be damaged by late frosts. Succeeds in most well-drained moderately fertile soils, growing best in full sun but tolerating light shade.
Full cultivation guide →Rhus integrifolia
Rhus integrifolia
Family: Anacardiaceae
Cultivation
Rhus integrifolia is not very cold-hardy, tolerating occasional falls in temperature to around -5°c when it is fully dormant. It requires hot summers if it is to thrive, since this ensures that its new growth is fully developed and ripened - in areas with cool summers it will be even more cold-sensitive. Older plants become somewhat hardier and so it is worthwhile growing them on for a few years in pots with some winter protection (such as a cold greenhouse) in areas towards the edge of their hardiness.
Full cultivation guide →Rhus microphylla
Rhus microphylla
Family: Anacardiaceae
Cultivation
Rhus microphylla is native to arid and semi-arid regions of southern N. America, where it ca be found at elevations up to 1,800 metres. Temperatures can range from up to 40°c in the summer, falling sometimes below freezing in the winter.
Full cultivation guide →Rhus ovata
Rhus ovata
Family: Anacardiaceae
Cultivation
Rhus ovata is not very cold-hardy, tolerating occasional, short-lived temperatures falling to around -5°c when it is dormant. It requires hot summers if it is to thrive - in areas with cool summers the wood fails to ripen properly and is then even more susceptible to winter damage. The young growth in spring is also very susceptible to cold and can be damaged by late frosts.
Full cultivation guide →Rhus potaninii
Rhus potaninii
Family: Anacardiaceae
Cultivation
Rhus poteninii is a moderatley cold-hardy plant, able to tolerate temperatures down to around -25°c when fully dormant. It grows best in areas with hot summers. In areas with cooler summers (even if the winters are mild), such as the maritime regions of the temperate zone, it often grows poorly, failing to properly ripen its wood and suffering frost damage over the winter.
Full cultivation guide →Rhus punjabensis
Rhus punjabensis
Family: Anacardiaceae
Cultivation
Rhus punjaensis is a moderatley cold-hardy plant, able to tolerate temperatures down to around -20°c when fully dormant. It grows best in areas with hot summers. In areas with cooler summers (even if the winters are mild), such as the maritime regions of the temperate zone, it often grows poorly, failing to properly ripen its wood and suffering frost damage over the winter.

Rhus taitensis
Rhus taitensis
Family: Anacardiaceae
Cultivation
A dioecious species, both male and female forms need to be grown if seed is required.
Full cultivation guide →Rhus trilobata
Rhus trilobata
Family: Anacardiaceae
Cultivation
Rhus trilobata prefers a mean annual rainfall within the range 250 - 500mm, though is adapted to a wide range of climates. It is known to thrive in areas where the average monthly temperature of the coldest month can be as low as -11°c and also where the average monthly temperature of the hottest month can be 26°c. The young growth in spring is not very cold tolerant and can be damaged by late frosts.
Full cultivation guide →Rhus typhina
Rhus typhina
Family: Anacardiaceae
Cultivation
Rhus typhina is a very cold-hardy plant, when fully dormant it can tolerate temperatures down to at least -25°c. However, the young growth in spring is more sensitive and can be damaged by late frosts. It can tolerate semi-arid climates with mean annual rainfall as low as 300mm, though it prefers moister climates with ainfall to 1,200mm or more.
Full cultivation guide →Rhus virens
Rhus virens
Family: Anacardiaceae
Cultivation
Rhus virens is native in warm temperate to tropical, semi-arid regions of southern N. America, where it can be found at elevations up to 2,250 metres. It requires hot summers if it is to thrive and is unlikely to withstand any more than light frosts with occasional temperatures down to around -5 to -8°c.

Rhus × pulvinata
Family: Anacardiaceae
Cultivation
Rhus x pulvinata is a very hardy plant, when fully dormant it can tolerate temperatures down to at least -25°c. However, the young growth in spring is much more sensitive and can be damaged by late frosts. Easily grown in a wide range of soils, from dry to moist, acidic or alkaline, including shallow chalk soils.
