Nirrhe is a handsome shrub/small tree that is native to central and southern Chile in moist woods. A slow growing plant with divided leaves that turn brilliant red in fall before dropping. This is the cold hardiest member of this genus enduring temperatures slightly below 0ºF with no damage. Unfortunately, it can be slow to establish and it requires moisture retentive soil that is high in organic matter. Regular deep summer soaks. Best with a cool root run. Roots in the shade tops in the sun. 2″ cupped 4 petalled pure white flowers erupt over the plant in July/August. The interior of the flowers house a boss of showy stamens tipped with purple pollen. Best with protection from hot afternoon sun. Flowers can fry even in short heatwaves so a cool position is suggested. To 14′ in 10 years and 6′ wide. Establishes faster with richly amended soil. Fall color, though late in the season is often spectacular red/ orange. Very slow to finish in a nursery container and not a fast growing plant over all. Wonderful surprise when it blooms during our hottest time of the year.
Eucryphia x ‘Nymansay’
Columnar evergreen tree that is ideally sized for small urban gardens and blooms in mid to late summer. Large white flowers are profuse on every stem. There is a central boss of long stamens tipped with pink pollen. Blooms July-August. Full sun to light overstory shade and rich soil with regular summer water to establish. To 18′ + in 10 years and less than half as wide. The evergreen divided leaves are glossy and pretty year round. Grows about 2′- 3′ a year when established. Young trees are somewhat sparse but they fill in significantly with age becoming very dense upright rounded trees with time. Locate out of the path of subfreezing east wind. If you are in a wind zone place the tree on the west or south side of a structure. In central Portland this is less of an issue. Gains tremendous cold hardiness with age. Protect young plants from temperatures below 15ºF- established plants can take brief drops to 0ºF. Amazing in bloom and wild life thinks so too. Cold damaged foliage recovers very quickly in spring- by May you would have no idea. Injury happens in cold gardens about once every 5 years. Majestic tree in age. South America.
Eucryphia x intermedia ‘Rostrevor’
Possibly the best Eucryphia for our climate in ease of culture, amount of flowers, and hardiness. This evergreen tree grows quickly when young. In youth it tends to be a somewhat sparse tree but with age it increases in density markedly. In July/August the whole tree is draped in pure white 2″ blossoms with a central boss of stamens holding raspberry pink pollen. Grows about 2′-3′ a year or more in rich, well drained soil with regular summer irrigation. Established trees can take summer drought. Cold hardiness increases dramatically with the age of the plant. Protect small trees from arctic conditions (below 20ºF). The divided deep green leaves are good looking year round. To 18′ tall and 5′ wide in a columnar form. Hybrid between two Chilean Eucryphia species including the hardiest E. glutinosa (Zone 6)- it inherits cold hardiness from that parent. Full sun.
