Eucryphia


Eucryphia is a small genus of trees or large shrubs of the Antarctic flora, native to the south temperate regions of South America and coastal eastern Australia. Traditionally placed in a family of their own, the Eucryphiaceae, more recent classifications place them in the Cunoniaceae. There are seven species, two in South America and five in Australia, and several named hybrids. They are mostly evergreen though one species (E. glutinosa) is usually deciduous.

The leaves are opposite, and either simple or pinnate with 3-13 leaflets. The flowers are produced in late summer or autumn, are showy and sweetly scented, 3-6 cm diameter, with four creamy-white petals, and numerous stamens and styles. The fruit is a woody capsule 1-1.5 cm long containing several seeds, and maturing in 12-15 months.

The generic name is derived from the Greek for "well hidden".

Hybrids and cultivars

E. intermedia (E. glutinosa E. lucida)

E. hillieri (E. moorei E. lucida): Developed from a self-sown seedling at the nursery of Hillier & Sons, Chandlers ford in Hampshire around 1953.

E. nymansensis (E. cordifolia E. glutinosa), also known as E. "Nymansay", originated from Nyman's Garden in Sussex, and won an Award of Merit from the Royal Horticultural Society in London in 1925. '''Eucryphia x nymansensis 'Nymans Silver' - '''is a sport discovered at Nymans Garden, Sussex in 2005. It is a variegated form with serrated oval leaves that are outlined in creamy white. It was discovered growing on a E. x nymansensis within the garden. It is considered to be faster growing and more columnar in nature. The name 'Nymans Silver' was proposed by Philip Holmes, Deputy Head Gardener at Nymans.' [*]

Uses

The species and their hybrids are attractive small trees for gardens, typically with a slender conic crown when young, though widening with age. They are valued for their conspicuous scented flowers, produced in late summer and autumn when few or no other trees are in flower. Cultivation is restricted to areas with mild winters, cool summers and good rainfall; away from their native areas, this restricts them to the Atlantic coastal regions of Europe, the Pacific Northwest of North America, and New Zealand.

Many of the species and hybrids may be seen at The Tasmanian Arboretum.
