A most unusual plant with a look like no other we can grow in the UK. A tall dense shrub or small tree with linear evergreen needle-like foliage looking more like a conifer, though actually a member of the Protea family from Tasmania and SE Australia. Clusters of attractive white flowers are produced in abundance during April and May. Not for very limy soils.
Hamamelis x intermedia 'Anne' (new)
An unusual clone, this cultivar from Holland has long bright yellow petals, seen on the bare branches in winter. A medium sized spreading shrub for any reasonable soil.
Hamamelis x intermedia 'Aphrodite'
A very large flowered cultivar with slightly fragrant deep-orange flowers borne en-masse in late winter/early spring on spreading branches, considerably later than some clones. Autumn colour rich orange and red. For any reasonable soil.
Hamamelis x intermedia 'Arnold Promise'
One of the very first clones of this hybrid Witch Hazel ever raised and still highly regarded. A vigorous cultivar making a large wide spreading bush, the branches profusely covered in bright yellow flowers towards the end of winter. Any reasonable soil. Award of Garden Merit.
Hamamelis x intermedia 'Nina'
A Danish witch hazel selection with long, clear yellow petals to the flowers, seen in mid to late winter, on a vigorous rounded shrub to 4m tall and of a similar width. Autumn colour is a deep butter yellow.
Hamamelis x intermedia 'Orange Peel'
A witch hazel with clear orange sweetly scented large flowers on a shrub to 3.5m high and round, though upright when young. The foliage is orbicular, turning yellow orange and red in autumn and the flowers, as is often the case, are produced in mid to late winter.
Heimia salicifolia (new)
A rarely grown and relatively unknown, but hardy and attractive narrow-leaved small shrub ranging from the Southern USA to South America. Small rounded yellow flowers are produced from July to September. Up to 1.2m tall for sun or semi-shade. Leaves contain psychoactive alkaloids and have been used for shamanic purposes for aeons.
Helwingia chinensis - Narrow leaf form
One of only 3 members of the Helwingiaceae, this Chinese species is rather similar to H. himalaica. Forming a vigorous evergreen shrub to about 2m or more with rather attractive, glossy, willow like foliage, emerging coppery-red and edged with small teeth. Green purple flowers open in the centre of the leaf (!) in summer, followed by black fruit. Hardy.
Helwingia japonica - broad leaved form
A small obscure deciduous hardy shrub with a wide distribution in Asia. This is a broad leaved form with ovate leaves; the veins conspicuously impressed on the upper surface. Little umbels of green flowers are, most bizarrely, borne in the centre of the leaf, followed by small black fruit on females. Reaches approx 1m or more high. For sun or shade.
The 'Seven Son Flower of Zhejiang'. Only introduced from China in 1981 this vigorous, easy, very hardy and attractive large shrub has proved its worth. The foliage has 3 prominent veins and each leaf curls under the branch creating a tube effect. Clusters of scented white starry flowers are borne in late summer, the calyx turning red if it's warm.
Hibiscus sino-syriacus 'Lilac Queen'
Deserving of far wider planting, this is closely related to the common hardy Hibiscus but far superior with much larger sage-green foliage, more vigorous growth and, in this form, beautiful lilac flushed flowers with garnet-red bases. These are also larger than H. syriacus, and with thicker petals. Easy in a sunny position in well drained soil.
Hibiscus sinosyriacus 'Ruby Glow'
A very rarely seen relative of the hardy Hibiscus. This species is from China and has much wider sage-green leaves on a more vigorous, spreading bush, with flowers of a more substantial nature. In this form the white petals have a red base. Full sun in any reasonable soil. This is virtually unknown and should, along with the other clones, be more widely planted.
Hippophae rhamnoides subsp. sinensis LSE 15724
Very different from the straight species, this rarity from China forms a round headed small tree with a thick trunk and semi-weeping, arching branches. The slightly broader foliage is green above and grey beneath. Very tough and easy, eventually reaching up to about 8m tall with a trunk up to 60cm thick.
Hippophae rhamnoides tall form
Derived from plants originally collected in Turkey which have a distinctly tall upright growth habit, but with pendent outer branches, reaching potentially 10m tall. Otherwise, sharing all the same characteristics of the species, being very hardy, very drought tolerant, with very narrow silver leaves and spiny stems. Suckers from the roots need to be removed or enjoyed.
Hoheria 'Ace of Spades'
A new British cultivar, possibly H. angustifolia x H. lyallii, selected for its triangular deeply lobed leaves and masses of rounded white flowers in July. A strong growing, tall, deciduous shrub or small tree eventually. Easy, even on thin dry soils, and best in full sun. No Hoheria is anything but a fine addition to any garden.
Hoheria 'Borde Hill' (new)
Highly confused in the trade due to plants being raised from seed, this is the true form, renowned for its distinctive very slim columnar growth form. Considered a hybrid of H. sexstylosa and H. angustifolia. As ever, frothing masses of white star-like flowers in July/August and great vigour. Makes an evergreen columnar shrub or small tree to about 6m.
Hoheria 'Glory of Amlwch'
A magnificent large, semi-evergreen shrub absolutely smothered in scented white, cherry-blossom like flowers crowded on the branches in late July, early Aug, an otherwise fairly dull time in the garden. Enjoys sun and a little shelter in cold areas. In my experience very good in poor limy soil.
From New Zealand comes this, the smallest leaved member of Hoheria. Makes a tall slim evergreen shrub or small tree with diminutive leaves and masses of starry little white flowers in July/August. Easy in most soils, even very thin ones, and very vigorous too. This is usually a tangle of wiry stems in its early years but then matures and grows up, as it were.
Hoheria x lanceolata Clone 1
H. angustifolia x sexstylosa. A superb, vigorous, upright, perfectly hardy, evergreen large shrub or small tree. The dark green foliage is slim, willowy and lightly lobed on slightly pendulous outer branches, smothered in early August with clouds of fragrant, starry white flowers. This plant has grown into a very handsome specimen with me on poor limestone soil. A favourite.
Hovenia dulcis NJM 11.003
The Japanese Raisin Tree is actually native to China and the Himalaya, but cultivated elsewhere for the edible branches of the inflorescences. Yes indeed, it's not the fruit you want to eat with this one, but the fleshy reddish twigs they perch on! We found this growing in a village in Guizhou, China where it made a small to medium sized deciduous hardy tree.
