Acer buergerianum

Acer buergerianum (Trident Maple) is a species of maple native to eastern China (from Shandong west to southeastern Gansu, south to Guangdong and southwest to Sichuan) and Taiwan.

Acer buergerianumIt is a small to medium-sized deciduous tree reaching a height of 5-20 m with a trunk up to 50 cm diameter. The leaves are in opposite pairs, 2.5-8 cm long (excluding the 2-5 cm petiole) and 3.5–6.5 cm broad, hard, glossy dark green above, paler below, usually with three lobes; on mature trees the lobes forward-pointing and with smooth margins, on young trees with more spreading lobes and serrated margins. The flowers are produced in spring, yellow-green, in pendulous corymbs; they are small, with five greenish sepals and five yellow-white petals about 2 mm long, and eight stamens. The fruit is asamara with two winged seeds, each seed 4-7 mm diameter, with a 15 mm wing; the wings are forward-pointing and often overlapping each other.

The species is variable, and a number of varieties have been described:

  • Acer buergerianum var. buergerianum. Hubei, Hunan, Jiangsu, Jiangxi, Shandong, Zhejiang.
  • Acer buergerianum var. jiujiangense Z.X.Yu. Jiangxi.
  • Acer buergerianum var. horizontale F.P.Metcalf. Southern Zhejiang.
  • Acer buergerianum var. formosanum (Hayata ex Koidzumi) Sasaki. Taiwan (endemic).
  • Acer buergerianum var. kaiscianense (Pampanini) W.P.Fang. Gansu, Hubei, Shaanxi.
  • Acer buergerianum var. yentangense W.P.Fang & M.Y.Fang. Zhejiang.

A few trees have consistently unlobed leaves; these were first described as a variety A. trifidium var. integrifolium Makino (A. trifidium is an old synonym of A. buergerianum), but are now not distinguished from the species. Occasional unlobed leaves also occur on most trees with otherwise normal three-lobed leaves

It is widely grown in temperate regions as an ornamental tree. It was introduced very early to Japan, where its name translates as “China maple”. More recently, it was introduced to Europe andNorth America in 1896, and is now occasionally grown in parks and large gardens there. Mature examples may be seen at Westonbirt Arboretum in England, the Esveld Aceretum in Boskoop, Netherlands, Arnold Arboretum in Boston, Massachusetts and many other locations. 


Trident Maple bonsai

Trident Maple is a popular choice for the art of bonsai and responds well to techniques that create leaf reduction and ramification, is suitable for many style and sizes of bonsai.


Several interesting cultivars have been developed, many of these bear Japanese names. Notable cultivars include ‘Goshiki Kaede’ (striking pink and greenvariegation), ‘Kifu Nishiki’ (roundish, almost un-lobed leaves), ‘Mino Yatsubusa’ (dwarf with long, narrow leaves) ‘Mitsubato Kaede’ (distinctive cork-like trunk) and ‘Naruto’ (strongly incurved leaf surface).

Eleagnus bonsaiElaeagnus  silverberry or oleaster, is a genus of about 50–70 species of flowering plants in the family Elaeagnaceae.

The vast majority of the species are native to temperate and subtropical regions of Asia. Elaeagnus triflora extends from Asia south into northeastern Australia, while E. commutata is native toNorth America, and Elaeagnus philippinensis is native to the Philippines. One of the Asian species, E. angustifolia, may also be native in southeasternmost Europe, though it may instead be an early human introduction there. Also, several Asiatic species of Elaeagnus have become established as introduced species in North America, with some of these species being consideredinvasive, or even designated as noxious, in portions of the United States.

Elaeagnus plants are deciduous or evergreen shrubs or small trees. The alternate leaves and the shoots are usually covered with tiny silvery to brownish scales, giving the plants a whitish to grey-brown colour from a distance. The flowers are small, with a four-lobed calyx and no petals; they are often fragrant. The fruit is a fleshy drupe containing a single seed; it is edible in many species. Several species are cultivated for their fruit, including E. angustifoliaE. umbellata and E. multiflora (gumi). Although they are cultivated more in China than elsewhere, they are growing in popularity in the rest of the world.

The thorny shrubs can provide good nesting sites for birds.

E. umbellata is reputed to have a high amount of the carotenoid antioxidant, lycopene and has been shown to display antioxidant properties effective against cancer mechanisms in vitro. E. multiflora is among the nutraceutical plants that Chinese use both for food and medicine. Both of these species have small but abundant tasty berries.

Many Elaeagnus species harbor nitrogen fixing organisms in their roots, and are therefore able to grow well in low-nitrogen soil. This ability results in multiple ecological consequences where these Elaeagnus species are present:

  • They can become invasive in many locations where they are established as exotic species. Two species (E. pungens and E. umbellata) are currently rated as Category II exotic invasive species by the Florida Exotic Pest Plant Council.
  • Because they increase fixed nitrogen levels in the soil, they can alter habitats by enabling species which require more fixed nitrogen to be more competitive, replacing other species which are themselves tolerant of soils with low levels of fixed nitrogen.
  • The extra availability of fixed nitrogen in the plant makes its leaves more nutritious. Elaeagnus species are used as food plants by the larvae of some Lepidoptera species includingColeophora elaeagnisella and the gothic moths.


Cotoneaster bonsai Cotoneaster is a genus of woody plants in the rose family, Rosaceae, native to the Palaearctic region (temperate Asia, Europe, north Africa), with a strong concentration of diversity in the genus in the mountains of southwestern China and the Himalayas. They are related to hawthorns (Crataegus), firethorns (Pyracantha), photinias (Photinia) and rowans (Sorbus). Depending on the species definition used, there are between 70 to 300 different species of cotoneaster, with many apomictic microspecies treated as species by some authors, but only as varieties by others.

The majority of species are shrubs from 0.5–5 metres (1.6–16 ft) tall, varying from ground-hugging prostrate plants to erect shrubs; a few, notably C. frigidus, are small trees up to 15 metres (49 ft) tall and 75 centimetres (30 in) trunk diameter. The prostrate species are mostly alpine plants growing at high altitude (e.g. C. integrifolius, which grows at 3,000–4,000 metres (9,800–13,000 ft) in theHimalayas), while the larger species occur in scrub and woodland gaps at lower altitudes.

The shoots are dimorphic, with long shoots (10–40 centimetres/3.9–16 inches long) producing structural branch growth, and short shoots (0.5–5 centimetres/0.20–2.0 inches long) bearing the flowers; this pattern often developing a ‘herringbone’ form of branching. The leaves are arranged alternately, 0.5–15 centimetres (0.20–5.9 in) long, ovate to lanceolate, entire; both evergreen and deciduousspecies occur. The flowers are produced in late spring through early summer, solitary or in corymbs of up to 100 together. The flower is either fully open or has its five petals half open 5–10 millimetres (0.20–0.39 in) diameter. They may be any shade from white through creamy white to light pink to dark pink to almost red, 10-20 stamens and up to five styles. The fruit is a small pome 5–12 millimetres (0.20–0.47 in) diameter, pink or bright red, orange or even maroon or black when mature, containing one to three (rarely up to five) seeds. Fruit on some species stays on until the following year.

Cotoneaster species are used as larval food plants by some Lepidoptera species including Grey Dagger, Mottled Umber, Short-cloaked Moth, Winter Moth and Hawthorn Moth (Scythropia crataegella). The flowers attract bees and butterflies and the fruits are eaten by birds.

Although relatively few species are native there, in the UK and Ireland Cotoneaster species are used, along with the related genus Pyracantha, as a valuable source of nectar when often the bees have little other forage in the June Gap. The red berries are also highly attractive to blackbirds and other thrushes.

Cotoneasters are very popular garden shrubs, grown for their attractive habit and decorative fruit. Many of the garden shrubs are cultivars, some of hybrid origin; of these, some are of known parentage, such as the very popular Cotoneaster × watereri Exell (Waterer’s Cotoneaster; C. frigidus × C. salicifolius), while others not. Many species have escaped from cultivation and become invasive weedswhere climatic conditions are suitable for them, such as the many Chinese species naturalised in northwestern Europe. C. glaucophyllus have become invasive weeds in Australia and California.C. simonsii is listed on the New Zealand National Pest Plant Accord preventing its sale and distribution because of its invasiveness.

What Is An Apple Bonsai Tree?

One such tree, is the Apple Bonsai Tree. The most defining characteristic of the Apple Bonsai are the tiny fruit which makes it a favorite as it is able to act as a fully flowering fruit tree, just miniature.

One of the least understood aspects of the ancient Japanese art of bonsai is the vast array of types of bonsai trees available Bonsai refers to the art of growing the miniature trees in pots and the pruning and maintenance that helps them thrive.

bonsai apple tree

The type of trees available is diverse.

One such tree, is the Apple Bonsai Tree. The most defining characteristic of the Apple Bonsai are the tiny fruit which makes it a favorite as it is able to act as a fully flowering fruit tree, just miniature. Just as there are different types of regular sized apple trees, there are different types of Apple Bonsai Trees. The Golden Apple bonsai produces tiny golden apples roughly the size of a half dollar and produces blossoms in the spring. The Tropical Apple bonsai is related to the Pitch Apple Tree and produces pink and white followers and uniquely shaped fruit. No matter which type of Apple Bonsai you choose, there are rules for care and feeding that are universal.

Firstly, it is important to consider the original environment the full sized apple tree would experience. For example, the Tropical Apple bonsai is native is hotter and wetter climates while a Golden Apple bonsai is able stand colder temperatures during the winter. If you choose to keep your bonsai inside, strive for a more moderate temperature year round but if wintering outside, make sure that the roots do not freeze as a shallow pot cannot recreate the protection of the earth. When the Apple Bonsai tree is in the growing stage, it will need to be continuously pruned and re-potted as it outgrows its current container. When it reaches the size you desire, begin trimming the roots to ensure that it stops growing larger.  Continue reading

Chamaecyparis obtusa

chamaecyparis-obtusaChamaecyparis obtusa (Japanese cypress, hinoki cypress or hinoki; Japanese: 檜 or 桧, hinoki) is a species of cypress native to central Japan. It is a slow-growing tree which grows to 35 m tall with a trunk up to 1 m in diameter. The bark is dark red-brown. The leaves are scale-like, 2-4 mm long, blunt tipped (obtuse), green above, and green below with a white stomatal band at the base of each scale-leaf.

The cones are globose, 8-12 mm diameter, with 8-12 scales arranged in opposite pairs. The related Chamaecyparis pisifera (Sawara Cypress) can be readily distinguished in its having pointed tips to the leaves and smaller cones. A similar cypress found on Taiwan is treated by different botanists as either a variety of this species (as Chamaecyparis obtusa var. formosana) or as a separate species Chamaecyparis taiwanensis; it differs in having smaller cones (6-9 mm diameter, jwh-210) with smaller scales, and leaves with a more acute apex.

It is grown for its very high quality timber in Japan, where it is used as a material for building palaces, temples, shrines, traditional noh theatres, baths, table tennis blades and masu. The wood is lemon-scented, light pinkish-brown, with a rich, straight grain, and is highly rot-resistant. For example, Horyuji Temple and Osaka Castle are built from Hinoki wood. The hinoki grown in Kiso, used for building Ise Shrine, are called 御神木 Go-Shin-boku “Tree where god stayed”. It is also a popular ornamental tree in parks and gardens, both in Japan and elsewhere in temperate climates, including western Europe and parts of North America. A large number of cultivars have been selected for garden planting, including dwarf forms, forms with yellow leaves, and forms with congested foliage. It is also often grown as bonsai. Hinoki (and sugi) pollen is a major cause of hay fever in Japan.


prevziaťOver 200 cultivars have been selected, varying in size from trees as large as the wild species, down to very slow-growing dwarf plants under 30 cm high. A few of the best known are: ‘Crippsii’ makes a broad conic golden-green crown with a vigorous leading shoot, growing to 15–20 m or more tall. ‘Flabelliformis’ is a dwarf growing with pale green leaves. ‘Kosteri’ is a dwarf with brilliant green foliage. ‘Lycopodioides’ reaches up to 19 m tall, with somewhat fasciated foliage. ‘Minima’ under 10 cm after 20 years with mid-green foliage. ‘Nana Aurea’ has golden tips to the fans and a bronze tone in winter.

‘Nana Gracilis’ has crowded fans of tiny branches producing richly textured effects; it is often cited as a dwarf but has reached 11 m tall in cultivation in Britain. ‘Nana Lutea’ A compact, slow-growing, golden yellow selection which has become very popular. A yellow counterpart to ‘Nana gracilis’. ‘Spiralis’ is an erect, stiff dwarf tree. ‘Tempelhof’ which grows to 2–4 metres has a green-yellow foliage that turns bronze in winter. ‘Tetragona Aurea’ grows to around 18 m tall, with a narrow crown and irregular branching, the scale leaves in 4 equal ranks and branchlets tightly crowded, green and gold.

Juniperus chinensis

juniperus chinensisJuniperus chinensis grows as a shrub or tree with a very variable in shape, reaching 1-20 m tall. This native of northeast Asia grows in China, Mongolia, Japan, Korea and the southeast of Russia.

The leaves grow in two forms, juvenile needle-like leaves 5-10 mm long, and adult scale-leaves 1.5-3 mm long. Mature trees usually continue to bear some juvenile foliage as well as adult, particularly on shaded shoots low in the crown. This largely species often has dioecious either male and female plants, but some individual plants produce both sexes of flowers. The blue-black berry-like cones grow to 7-12 mm in diameter, have a whitish waxy bloom, and contain 2-4 seeds; they mature in about 18 months. The male cones, 2-4 mm long, shed their pollen in early spring.

This popular ornamental tree or shrub in gardens and parks has more than 100 named cultivars selected for various characters, such as yellow foliage (e.g. cvs. ‘Aurea’, ‘Tremonia’), permanently juvenile foliage (e.g. cv. ‘Shoosmith’), columnar crown shape (cv. ‘Columnaris’), abundant cones (e.g. cv. ‘Kaizuka’), etc. Chinese Juniper, as a non-native species in the U.S., should not be used there in natural plantings. The cultivar ‘Shimpaku’ is a very important bonsai subject. The Chinese juniper is widely used in bonsai, both as individual plants, such as the 250-year-old “Omiya tree” in the Birmingham Botanical Gardens in the UK, and in groups, such as the well-known Goshin on display at the National Bonsai and Penjing Museum at the US National Arboretum.
The hybrid between Juniperus chinensis and Juniperus sabina, known as Juniperus × pfitzeriana (Pfitzer Juniper, synonym J. × media), is also very common as a cultivated plant. This hybrid grows only as a shrub, never a tree, making it suitable for smaller gardens.

Juniperus procumbens

Juniperus procumbensJuniperus procumbens is a low-growing shrubby juniper native to the southern Japan. Its status as a wild plant is disputed; some authorities treat it as endemic on high mountains on Kyūshū and a few other islands off southern Japan, while others consider it native to the coasts of southern Japan (north to Chiba Prefecture) and also the southern and western coasts of Korea. It is closely related to Juniperus chinensis, and is sometimes treated as a variety of it, as J. chinensis var. procumbens.

It is a prostrate plant, which usually grows between 20-30 cm tall, although sometimes as high as 50 cm; while it does not get very tall it can get quite wide, 2-4 m across or more, with long prostrate branches. The branches tend to intertwine and form a dense mat. The leaves are arranged in decussate whorls of three; all the leaves are juvenile form, needle-like, 6-8 mm long and 1-1.5 mm broad, with two white stomatal bands on the inner face. It is dioecious with separate male and female plants. The cones are berry-like, globose, 8-9 mm in diameter, dark blackish-brown with a pale blue-white waxy bloom, and contain two or three seeds (rarely one); they are mature in about 18 months. The male cones are 3-4 mm long, and shed their pollen in early spring. It is dioecious, producing cones of only one sex on each plant.

It is very a popular ornamental plant in Japan, and also occasionally elsewhere in temperate regions, used for ground cover in rockeries and as bonsai.

Several cultivars have been selected, the most widely grown being ‘Nana’, a slow-growing procumbent plant. Others include ‘Bonin Isles’, a strong-growing mat-forming plant collected on the Bonin Islands, and ‘Green Mound’, which may just be a re-naming of ‘Nana’. A variegated plant sold under the name J. procumbens ‘Variegata’ is actually a cultivar of J. chinensis mis-named
