Greening Deserts and Leipzig Palms Cultivating Rare Palm Trees

Greening Deserts projects like Leipzig Palms (LE Palms) do not conservating and cultivating just endangered plants like rare trees. Beautiful decorative and ornamental palm trees are another speciality.

We care for endangered animals and plants around the world. Show some love and support our projects by constructive feedback or by buying some palms or palm products. http://www.lepalms.shop 

Bismarckia (Bismarck Palm Tree) is a monotypic genus of flowering plant in the palm family endemic to western and northern Madagascar where they grow in open grassland. The genus is named for the first chancellor of the German Empire Otto von Bismarck and the epithet for its only species, Bismarckia nobilis, comes from Latin for ‘noble’.

Bismarckia nobilis grows from solitary trunks, gray to tan in color, which show ringed indentations from old leaf bases. Trunks are 30 to 45 cm in diameter, slightly bulging at the base, and free of leaf bases in all but its youngest parts. In their natural habitat they can reach above 25 meters in height but usually get no taller than 12 m in cultivation. The nearly rounded leaves are enormous in maturity, over 3 m wide, and are divided to a third its length into 20 or more stiff, once-folded segments, themselves split on the ends. The leaves are induplicate and costapalmate, producing a wedge-shaped hastula where the blade and petiole meet. Petioles are 2–3 m, slightly armed, and are covered in a white wax as well as cinnamon-colored caducous scales; the nearly-spherical leaf crown is 7.5 m wide and 6 m tall. Most cultivated Bismarckias feature silver-blue foliage although a green leaf variety exists (which is less hardy to cold). These palms are dioecious and produce pendent, interfoliar inflorescences of small brown flowers which, in female plants, mature to a brown ovoid drupe, each containing a single seed.

Found only in Madagascar, an island well known for its rich diversity of unique taxa, Bismarckia is one genus among a diverse palm flora (some 170 palms of which 165 are solely in Madagascar). They grow in the plains of the central highlands, nearly reaching the western and northern coasts, in savannas of low grass, usually in lateritic soil. As much of this land has been cleared with fire for agricultural use, Bismarckias, along with other fire-resistant trees like Ravenala madagascariensis and Uapaca bojeri, are the most conspicuous components of this arid region.

Bismarck palms are grown throughout the tropics and subtropics under favorable microclimates. They are planted in several areas of Florida in the United States, as well as in a few areas of Southern California, and southern Arizona. It is also grown in many parts of Indonesia and Australia. Bismarck palms will suffer from cold damage but they quickly recover. The green variety is more cold sensitive than is the silver-gray variety. The green variety is damaged at 32 °F (0°), but the silver-gray variety will tolerate 28 °F (−3 °C) and will recover from 23 °F (−6 °C). While Bismarckia tolerate some drought, they thrive in areas with adequate rainfall. Because of their massive crowns, they need plenty of room in a landscape area.

Bismarck palms are easy to grow in the right environment as they are adaptable to a wide range of soils and prefer to have good drainage as the Bismarck does not like to have root rot. The Bismarck palm can adapt to either acidic or alkaline soil and prefers to be watered directly into the root system or sprayed through the palm heart. When planting the Bismarck palm make sure to not to cover up any part of the trunk, as this will lead to problems as the Bismarck palm is susceptible to be eaten by microorganisms that live naturally in soil and other mediums.

Palms or palm trees can be used for professional agriculture (ecofarming) and diverse forestry in dry and barren landscapes. Many palms are very drought- and heat-resistent. They can protect (by dropping shadow and holding water) other smaller plants around, for example crops or young trees.  Greening Deserts and Leipzig Palms refer to some palms as ‘protectors and wards from the desert’. They are also good to improve the climate and cool down whole cities or urban areas. We therefore recommend palm trees not only for German or European opencast mining areas (open pit deserts), but also for the reform of agriculture and forestry.

Leipzig Palms Improving Air Quality and Reducing Global Warming

Leipzig Palms (LE Palms) don’t just cultivating rare and endangered palms of the red list. We cultivating also palms for better air quality and for a more diverse environment. Diversity, conservation and environmental protection with palms are possible, especially in extreme environments like in dry and barren landscapes. Palms can filter the air from different toxic substances and cool down urban areas and bigger cities which heating up very much.  More and more droughts coming to Europe because of the human-made climate change and the resulting extreme weather. Together with Greening Deserts projects we want to reduce the global warming on a significant level.

Phoenix roebelenii, with common names of pygmy date palm, miniature date palm or just robellini, is a species of date palm native to southeastern Asia, from southwestern China (Yunnan Province), northern Laos and northern Vietnam.

The dwarf date palm is a multi-stemmed palm, in culture it remains sometimes with one stem. It forms clumps where stemless shoots grow around the base of higher trunks. The trunk becomes 1 to 2, rarely up to 3 m high. The diameter is up to 10 cm without sheaths. The trunk is upright or twisted, bright, becoming smooth in old age. He is occupied with diamond-shaped leaf bases.

The leaves are arched, 1 to 1.5, rarely 2 m long. The pseudostiel is about 50 cm long. The leaf sheath is reddish brown and fibrous. The acanthophylls (pinnae turned into thorns) are solitary or paired, about 12 on each side of the rhachis. They are orange-green and up to 8 cm long. The leaflets are regular, opposite, about 25 to 50 on each side of the rachis. They are linear, deep green to 40 cm long and 1.2 cm wide.

Barrow argued in 1998 that, because of the small area of distribution and the collection of wild plants for trade, a classification as vulnerable was warranted. However, the IUCN does not lead the species in its Red List. The Dwarf Date Palm is a popular ornamental plant in Europe. It can be found worldwide in botanical gardens and private collections.

The plant purifies the air of formaldehyde, xylenes and toluene.

Sabal and Palmetto Dwarf Palms

We cultivate also another dwarf palms like Sabal minor, because some palmetto palms are very resistent to heat and coldness. Hardy and robust palms are a speciality of LE Palms (Leipzig Palms).

Sabal minor, commonly known as the dwarf palmetto, is a small species of palm. It is native to the deep southeastern and south-central United States and northeastern Mexico. It is naturally found in a diversity of habitats, including maritime forests, swamps, floodplains, and occasionally on drier sites. It is often found growing in calcareous marl soil. Sabal minor is one of the most frost and cold tolerant among North American palms.

This palm’s native range spans on the Atlantic Coast from central Florida north to Monkey Island, North Carolina. On the Gulf Coast, it spans from central Florida to central Texas, Arkansas, north to southern Kansas, then south in the State of Nuevo León in Mexico.

The dwarf palmetto grows up to 1 m (rarely 3 m) in height, with a trunk up to 30 cm diameter. It is a fan palm (Arecaceae tribe Corypheae), with the leaves with a bare petiole terminating in a rounded fan of numerous leaflets. Each leaf is 1.5–2 m long, with 40 leaflets up to 80 cm long, conjoined over half of this length. The flowers are yellowish-white, 5 mm across, produced in large compound panicles up to 2 m long, extending out beyond the leaves. The fruit is a black drupe 1–1.3 cm long containing a single seed.

Sabal minor is one of the most cold hardy palms, second only to the needle palm, Rhapidophyllum hystrix. It is leaf hardy to near 0 F/-18 C, and has been known to survive brief periods of -5 F temperatures. It is generally cultivated in subtropical and warm temperate climates, however it needs hot and humid summers (tropical summer conditions) to grow well.
