Description. Eoniumy – perennial kustarnikovidnye or shallow, almost stemless herbaceous plants from 30 cm to 1 m in height. The leaves are succulent, obovate or spatulate, in most species at the edges with a cartilaginous cilia, gathered at the end of the branches in a rosette. Inflorescence terminal, often quite powerful (up to 1 m in height and A. virgineum A. urbicum). Perianth 6-membered, petals yellow, whitish or pink stamens in 2 times. Some species – monocarpic and die after flowering (A. nobile, A. glandulosum, A. tabulaeforme). The genus name comes from Greek.
aionios – long, eternal. About 40 species, not including natural hybrid forms, are endemic to the Canary Islands and Madeira. At home bloom lasts for two months. Grown, most succulent plants. but the soil mixture is desirable to add a little peat or humus.
Homeland. Spain, Portugal, Morocco, Sicily, Sardinia.
Sizes. To 1 m
Location. Eoniumu requiring maximum sun all year round. Inadequate lighting contributes to the formation of loose sockets, and premature leaf fall.
Temperature. Minimum temperature in winter for eoniuma about 10 “C., in the rest of the time up to 24″ C.
Substrate. Substrate eoniuma prepared as follows: the two parts of compost-based soil and one part coarse sand or perlite.
Humidity. Eoniumy resistant to air dry.
Watering. During the growth substrate keep wet for the rest of the time – a little dried out, but with dry leaves and excess eoniuma will shrink. During the period of every two weeks there is a weak fertilizer solution of liquid fertilizer. Provide eoniumu quiet in the winter. Over-watering causes the development of non-standard, weak, drooping plants.
Transplant. Every spring eonium-pot in a pot bigger. Newly planted plants should be firmly push into the substrate. After the transplant, watering very careful – a little so as not to cause rotting of the roots. Useful to add to the soil pieces of birch coals. Good drainage is required.
Reproduction. Propagated eonium spring or summer sowing seed or leaf and stem cuttings.
Special requirements. Better use of terracotta, not plastic pots, as adults eoniumy develop powerful aerial parts and can tip over, place props for higher plants.
Pests and diseases. Eoniumy mealybugs may be affected, including the root and scale insects. These pests are not always able to see the plants with large rosettes of leaves.
And as eonium may be affected by aphids and weevils, if the plant is in the summer in the garden. Inspect the plant for the early detection of pests.
Eonium arborescent – Aeonium arboreum – the most common type. This little branching shrub up to 90 cm in height (in the wild). Stems are erect, brownish. Fleshy leaves up to 6-7 cm long collected in dense rosettes that reach 20 cm in diameter. Leaves glabrous, the edges fringed soft hairs. The leaves can be of various shapes, such as round or spatulate, obtuse or sharply pointed at the end. The leaves are green, while the garden forms the edge of the green with purple or dark purple. Blooms bright yellow flowers in umbellate inflorescences. Inflorescence about 40 cm in height. Flowers 10 (rarely 9-11) – term, light yellow. Homeland – South-western and northern Morocco. Introduced in the middle of the XVII century. in many Mediterranean countries, which are often found in the wild in the wild state. There is also growing in South Africa, Argentina, California. The gardens are also bred decorative shape with dark red leaves – A. arboreum «Atropurpureum». Widespread tree species eoniuma – Schwarzkopf – with maroon, almost black leaves.
Eonium tarelkovidny – Aeonium tabulaeforme. Perennial herb with a short stem bearing a dense rosette of leaves. The leaves are tightly as shingles, in a plane, such as plates, 6-16 cm long, 2.5-4 cm wide, light green, naked, with long white hairs on the edges. The number of leaves in rosette can reach 200. Inflorescence 30-60 cm long. The flowers are 7-9-term (typically 8 – term), light yellow. These amazing pictures are quite flat outlet, built of thick, like tile, finding each other leaves. The diameter of these “plates” can reach 30 cm and is always a great pity that in 2-3 years the outlet center starts to rise, stretch, branched inflorescence is formed – and the plant dies.
Homeland – Canary Islands (Tenerife), where the species grows on coastal rocks at an altitude of 1000 m above sea level.
Eonium Haworth – Aeonium haworthii Webb et Berth. Obilnovetvyaschiysya shrub 30-60 cm in height and width. Lateral branches appear immediately below the leaf rosette. Initially, they are thin, and later become solid, they develop aerial roots. The leaves are gray-green, 2.5-5.5 cm long and 2-3 cm wide, rather thick, with cilia and a red stripe on the edges, gathered in a loose socket. Inflorescence pendulous, 15-30 cm in height. The flowers are 7-9-membered, pale yellow with a pink tinge. Homeland – Canary Islands (Tenerife). Grown in dry hot slopes at an altitude of 60 to 900 m above sea level.
Eonium noble – Aeonium nobile Praeg. The stem is a single, straight-line, up to 40 cm tall, 4-5 cm in thickness. Leaves in loose outlet, very thick, 20-30 cm long, 15-20 cm wide, 10-12 mm thick, bare (young-sticky nezhnoopushennye the edges). Inflorescence powerful – up to 60 cm in diameter. Flowers 7-8-membered, dark red. In large inflorescence develops to 50,000 flowers. Homeland – Canary Islands (Palm Island). Grows to a height of 800 m above sea level on a hot, but wet rocks.
Eonium Virginia – Aeonium virgineum Webb et Berth. Stemless or short-stemmed plant that has evolved over the leafy rosettes, resulting in formation of large groups such as pillows. Velvetovoopushennye leaves, bright green at the base of the pale pink with a pleasant scent of balsam, collected a loose socket. Young leaves with wavy edges. Inflorescence in the wild reaches 1 m in height. Flowers 6-9-membered, lemon-yellow. Homeland – Canary Islands (Gran Canaria).
Eonium decorative – Aeonium decorum Webb. Obilnovetvyaschiysya loose shrub up to 50 cm in height (Fig. 29). Stems rough, with diamond-shaped leaf traces and with more or less densely distributed white solid processes (prominences) at the top of the young shoots. Leaves in loose outlet, green, smooth, shiny with a pinkish tinge, 2.5-3 cm long, 1 to 1.5 cm wide. Apical inflorescence. Stems 30-45 cm long, light pink. Flowers 6-8-membered, pinkish-white. Homeland – Canary Islands (La Gomera Island.) It grows on rocks at an altitude of 100-300 m above sea level. One of the most common species in the culture.
Eonium home – Aeonium X domesticum Praeg. Small obilnovetvyaschiysya dense shrub 15-30 cm tall. Branches diverging from the woody base, initially they were spreading, then bend near the top. The leaves are dark green, 2 cm long and 1 cm wide, covered with glandular hairs. Co-flowers 10-20 cm in length. Flowers 7-8-membered, yellow. Elegant low bushes e. home (A. domesticum) typically do not exceed 30 cm, but in small miniatures of succulent plants, they may well serve as the main high element. Thin leafless trunks below, above – branching and form a crown of soft short-haired rounded, tapering to the base of the leaves are grayish-green color. Birthplace is unknown. This is probably a garden hybrid. This form and its form “Variegates» («Variegata») with white spots on the leaves often grown in greenhouses.
Eonium Lindley – Aeonium lindleyi Webb et Berth. Obilnovetvyaschiysya shrub up to 30 cm tall, with brown, cracked along the bark. The leaves are very thick, 2.5 cm long, 5-6 mm thick, bright green, nezhnoopushennye glandular hairs. Apical inflorescence. Flowers 8-9-membered, yellow. Homeland – Canary Islands (Tenerife), where this species grows on the slopes of the red-hot rocks.
Advice. From May to August eonium fertilize once a month a special fertilizer for cacti and other succulents, with a high content of potassium.
