Citrus ichangensis (C. cavaleriei)
One of the hardiest of all Citrus, this distinctive foliage plant can survive on a warm wall in many parts of the UK and even free standing in mild areas. A small to medium sized shrub with tapered ovate-elliptic leaves with the extended winged petiole as broad as the leaf blade (like Kaffir lime leaves). White flowers are followed by lemon shaped fruit if grown on a warm wall.
The Yellowwood from the SE USA forms a very attractive tree here, with unusual alternately pinnate, bold foliage, turning to an excellent clear yellow in autumn. The long drooping panicles of white pea flowers in June remind one of Wisteria. Easy in most places, enjoying sun.
A very rarely offered or seen Chinese tree of small to medium size for a sunny position. Attractive pinnate leaves open late, and the tree is smothered in large panicles of pink-tinged white pea flowers in July, but not usually on very young specimens. Bark is smooth and grey, and the autumn colour is an exceptional, glowing, clear golden yellow.
Cladrastis wilsonii W 1102
Almost extinct in cultivation and possibly none too common in the wild, this was never offered for sale, until now. These are grafts of the last known tree in cultivation in the UK (now dead) at Wisley. Closely related to the beautiful C. sinensis, but with larger flowers in smaller panicles. Excellent yellow autumn colour on this small hardy tree for any ordinary soil.
An invaluable late flowering large shrub to small tree. New foliage emerging burgundy flushed. Very fragrant white flowers held in maroon calyces borne in Aug/Sept, followed by bright blue berries, still subtended by the persistent calyxes. A tolerant and hardy species for acid or alkaline soils.
Clethra barbinervis 'White Star'
A new form of a desirable hardy medium to large shrub from Japan and S Korea, flowering at a younger age, with attractive exfoliating grey and pink-brown bark recalling a crape myrtle, Lagerstroemia. Long racemes of deliciously scented white flowers are seen in July/August, followed by red and yellow autumn colour. Requires lime free soil.
A variable species, now including many closely related entities, but always very handsome. A large shrub with long, broad, horizontally held, many flowered racemes of highly scented pure white flowers in late summer. Seen at its best with at least some shelter. Usually perfectly hardy in most parts of the UK. For lime free soil
Clethra kaipoensis NJM 11.020
A relatively new introduction from 1850m altitude in Guizhou, China, where it was a deciduous upright large shrub or small tree to 4m with rough, fissured bark. The terminal, branched, narrow-conical inflorescences are seen in late summer and are composed of multiple white flowers giving a fine fragrance. For lime free soil.
Clethra kaipoensis NJM 11.058
A relatively new introduction from 2000m altitude in Guizhou, China, where it was a deciduous upright large shrub or small tree to 4m with rough, fissured bark. The terminal, branched, narrow-conical inflorescences are seen in late summer and are composed of multiple white flowers from red-pink tinted stems, giving a fine fragrance. For lime free soil.
One of the finest of all late summer flowering shrubs, this makes a large deciduous bush for lime-free soils. Best suited away from the very coldest areas and requiring a sheltered site inland, this bears long racemes of fragrant white flowers in late summer.
Very rare in cultivation, this Eastern and North Eastern Mexican species is highly regarded by the few that grow it in North America. A large shrub for lime free soil, or given time a small tree, this has foliage that emerges reddy-bronze and turns to deep green later with long racemes of strongly cinnamon scented white flowers in summer. Certainly reasonably hardy.
Cleyera japonica var. japonica
A rare member of the Tea family from Japan, where it is the sacred tree of Shintoism. Forms a rigidly wide spreading, distinctly layered evergreen shrub with red-rimmed, green, leathery foliage, often red tinted in winter. Masses of fairly inconspicuous but wonderfully scented, small, translucent cream flowers in summer. Not suited to shallow chalk soils. Height 3m.
Colquhounia coccinea Schl 2458
This clone is thought to be the best in cultivation by Tony Schilling who introduced it. A tall deciduous shrub looking a little like a Buddleja in leaf, and a giant Salvia in flower, with lovely, scarlet, tubular flowers in late summer/autumn, at the ends of the branches. This is a good hardy form, for full sun and well drained soil. From the Milke Danda, Nepal, 2740m alt.
Cornus 'Eddie's White Wonder'
A hybrid between the American species C. florida and C. nuttallii, making a large shrub or small, compact tree, with layers of branches smothered in large white flower heads in spring. Leaves give brilliant autumn colour. Quite a sight in flower, closely resembling a good C. nuttallii.
A hybrid between C. florida and C. nuttallii resembling C. 'Eddies White Wonder' (same parentage), but of spreading habit. An old specimen at Kew was a most beautiful sight in full flower and made a very full, rounded small tree with branches to the ground. The inconspicuous flowers are surrounded by four large white bracts and smother the branches in May.
Cornus 'Stellar Pink'
Another product of the Cornus breeding program of Elwin Orton of Rutgers University, New Jersey, this hybrid of C. kousa and C. florida visually leans toward the former parent. Bearing a massed display of white to soft pink bracted flowers in mid summer on a rounded small tree to about 6m tall with spreading branches. For sun or part shade.
A hybrid of C. kousa and C. nuttallii bearing one of the most magnificent floral displays of any Cornus. The broad rounded clear white bracts that surround the flowers reach typically to 12 to 15cm across and occasionally to 17.5cm! They are borne in profusion on the spreading branches in June. Up to approx 6m tall by 8m across. For sun or semi shade.
Cornus aff. capitata NJM 12.048 (new)
A very interesting find from 2222m altitude in Manipur, NE India. Foliage much less hairy and smoother than C. capitata and in many ways closer to C. hongkongensis. The bracts are white and the fruit are huge, up to 6cm across and drop from the trees pale green, unlike all C. capitata known, which have smaller red fruit.
Cornus alternifolia 'Argentea'
Very distinct and extremely attractive medium to large shrub a bit like a miniature, multi-stemmed Wedding Cake Tree with layered, tabulate branching and silvery-white variegated leaves. Leaves are small however, giving an incredibly delicate effect. A plant deserving of a prime position.
Cornus capitata Hardy form
A highly regarded evergreen from the Himalaya and China, making a large shrub or small tree. Four large conspicuous, softest cream-yellow bracts per flower cover the branches in June, followed by a mass of pendulous edible strawberry-like fruit in October. Far hardier than the old stock in cultivation and proven hardy through Dec 2010 near here.
