Ballota pseudodictamnus Compact form B&M 8119 (new)
A Chris Brickell collection from Crete, this forms a smaller plant than usual, making a mound of small woolly grey foliage with soft purple flowers in summer, followed by persistent grey green sepals. One of the best small sub-shrubs for grey foliage effect. A hardy plant for sun and well drained soil.
Berberis hypokerina (new)
An exceptional species, discovered by Kingdon Ward in Upper Burma. This forms a small evergreen shrub to about 1m high usually, with striking holly-like leaves up to 15 x 6cm, green above and silvery-white beneath on a thicket of spineless purple stems. Masses of yellow flowers in spring, followed by dark-blue, white bloomed berries. Rarely obtainable.
Berberis insignis var. insignis
One of the very finest species, making a medium sized evergreen shrub 1.5 to 1.8m tall, distinct in its mainly spineless stems. The leaves are some of the largest found in Berberis species, looking more Mahonia-like, dark glossy-green, lanceolate to narrowly oval with short spiny teeth. Dense clusters of large pale yellow flowers in spring. Very rarely offered.
Berberis subacuminata NJM 09.165
Found at 2750m alt. on Fan Si Pan Mountain, N. Vietnam, near the Chinese border, this evergreen shrub made plants to about 2m tall, with leathery, prominently veined, elliptic-lanceolate leaves. Clusters of yellow flowers are seen in spring, followed by slightly bloomy black berries in autumn. Should have good hardiness from this altitude.
Berberis triacanthophora 'Cally Rose' (new)
An excellent new introduction and unique in having clusters of pink flowers with cream inner petals, borne in summer. The rich green foliage is very fine and narrow and a joy in itself. Makes an evergreen, spiny, free flowering shrub to 1.8m, for sun or shade. Purchased in Japan, but originally collected in China. Incorrectly sold as B. panlanensis 'Cally Rose'.
A highly sought after and desirable species from Chile making a large, evergreen shrub with polished, leathery, almost spineless leaves and long drooping racemes of saffron-yellow flowers in spring. Always in demand, hard to propagate, visually arresting in flower and rarely available. Easy and hardy.
Berberis xanthoclada NJM 11.007
Found at the top of Leigong Shan, Guizhou, China, at 2150m, this very unusual evergreen barberry is endemic to Guizhou and made a dense shrub to 2m with glossy green elliptic foliage and black fruit. Yellow flowers borne in spring/summer.
Betula albosinensis 'Bowling Green'
A form of this wonderful Chinese birch originally selected for its bark qualities from an Ernest Wilson collection growing at Werrington, Cornwall. The bark is a warm honey colour and peels off to reveal a darker, more cinnamon-brown underside. Makes a fast growing medium sized tree. Easy and hardy. Best as a group planting.
Betula albosinensis 'China Rose'
A new form of this wonderful species, selected, as so many good ones are, by Kenneth Ashburner. Making a fast growing medium sized tree, the bark on this is a really good saturated coppery-orange-red, with only a little white bloom when young. At its best close planted as a group of three, or cut back hard to form a multi-stem, but just one is pretty marvellous.
Betula albosinensis 'Chinese Garden'
The second form selected for its bark qualities from an Ernest Wilson collection growing at Werrington, Cornwall. The rich pinkish bark is darker than 'Bowling Green', the other selection from that garden. Makes a fast growing medium sized tree. Easy and hardy. Best as a group planting.
Betula albosinensis 'Pink Champagne'
Selected for its outstanding dusky pink bark, overlain with a persistent transparent layer of white betulin, the whole appearing pale pink. A new form of this marvellous Chinese birch, making a fast growing medium sized tree. Most effective as a close group of 3, but just one is beautiful. Hardy and easy. Originally from seed sent from Gansu, China.
Betula albosinensis 'Red Panda'
Yet another outstanding clone of this most desirable of birches, this time collected originally in Hubei Province, China. As usual the bark is difficult to describe, but the main base colour is a caramel-orange-red, much like a Red Panda, but there is also gold in there, with heavy horizontal lenticel banding throughout. Superb as a group, just fine as one.
Betula albosinensis var. septentrionalis Purdom 752
Originally collected in Gansu, China, by William Purdom in the early 1900's, this form has very attractive stems with bark of smoky mauves, buffs and satiny pinks. Makes a fast growing medium sized tree for most soils. Always most effective as a group, but one is still lovely.
Betula cylindrostachya (new)
A rare Himalayan birch making a vigorous small tree with large, glossy foliage on stout shoots covered in soft yellow hairs, the bark shiny greyish-black. The catkins in spring are long and showy, up to 14cm. For a sheltered position in milder areas where it makes a fast growing reliable tree. Fine specimens can be seen in both Cornwall and on the Wirral.
Betula dahurica 'Maurice Foster'
A new selection of this very distinct birch. The bark of the trunk and branches is particularly shaggy, composed of zillions of tightly shredded wisps of paper-thin sheets. In this form the outer bark is a dusky red-brown, peeling to reveal a silvery-grey inner layer. Very hardy and well suited to tough cold sites. Eventually makes a medium sized tree.
Betula ermanii 'Grayswood Hill'
This birch is one of the finest for all year bark and trunk interest. The normally heavily branching stem or stems are rich cream with naturally shedding bark peeling off in little strips. The new foliage is orangey-red on expansion. One of the finest of all birch and best planted as a group, so as to enjoy as much bark as possible. Hardy and easy in most places.
Betula ermanii 'Hakkoda Orange'
A colourful form of this Far Eastern species; the cream coloured papery bark naturally peeling off in strips to show warm pinkish-orange newer bark underneath. The branches tend to be less cream and more orange and the whole tree has striking horizontal lenticel banding on all bark surfaces. Will make a hardy medium sized tree for most soils. Collected N. Honshu.
Betula ermanii 'Mount Zao Purple'
A truly unique birch with the most amazing coloured bark. The base layer is a mistily bloomed deep chocolate-purple, heavily overlain with copper-orange patches and a mass of very prominent creamy lenticel banding. Reliable orange autumn colour. Quite exceptional as a single specimen, this would look amazing as a group planting. From N. Honshu, Japan.
Introduced from China in only 1985 and still a rarity in cultivation. Described as 'most handsome' by Ashburner and Mc Allistair. Leaves large, up to 16cm long, and the big clusters of male catkins are 'the showiest of all birches', being again up to 16cm long. The dark bark has conspicuous horizontal lenticels. Excellent yellow-orange autumn colour.
Betula luminifera (new)
Rarely sold or grown, this is a common tree in some parts of W. China. Very attractive very long male catkins in April and shining, dark, reddish-brown, cherry-like bark with conspicuous horizontal lenticels. Large deep green leaves persist until late autumn. Perfectly hardy even though very early to start into growth. A success in Holland and Belgium for eg.
