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 Cultivating Exotic and Endangered Tropical Palms

LE Palms (Leipzig Palms) cultivating also exotic and tropical palms, especially rare and endangered species. Together with Greening Deserts we want to cultivate also palms of the Red List which are in danger of extinction. For this work we need greenhouses and any support. That’s why we want to build a special greenhouse in the upcoming greening and research camp in the surface mining landscape nearby Leipzig in Saxony. If all runs good and we get finally financial support for this and other important conservation work we maybe can start on site with first preperations still this year.

We found many good and unused places around the lakes (Lakeland Neuseenland). At Cospudener, Markkleeberger and Zwenkauer lake is enough place for a first camp. We informed all responsibles many times and asked for free places, but got no concrete offers. Our demands or requests are still running and we hope to get finally concrete offers for possible places at the lakes. We need a place nearby the camp not just because of the palm cultivation, but also because of water research and the research on better irrigation methods and how to improve the waters or water quality – also for the important research of water plants. Everything is described and explained extensively on the Greening Deserts projects pages.

We already cultivating some rare palms, they growing very good here in Germany. Spring, summer and autumn are hot enough. Today we want to present one rare palm species which is well know because of their hearts of palm. The palm is a perfect houseplant and can be grown indoors.

Euterpe edulis, also Jussarapalme or Juçarapalme, is a palm species native in South America, which strong by the extraction of the palm hearts was decimated.

The species forms single strains, rarely is it multi-stemmed and then with few strains. The trunks are upright, 5 to 12 m high at one Diameter of 10 to 15 cm. The trunk surface is usually gray of lichen, at the base is a reddish-brown cone of adventitious roots. These have a diameter of 1 to 2 cm. The crown consists of 8 to 15 pinnate leaves. The leaf sheath is 0.8 to 1.4 m long, olive to dark green, sometimes with a reddish or orange tone. The surface is bare or covered with reddish-brown scales. The petiole is 13 to 54 cm long. The rhachis is 1.5 up to 3 m long. On each side sit 38 to 62 (rarely 70) leaflets. They are overhanging or hanging, almost opposite, regular arranged and provided with a clear midrib. The lowest Fieder is 29 to 50 cm long, the middle 49 to 80 cm and the Fieder the top 15 to 35 cm…

Euterpe edulis occurs on the Atlantic coast of Brazil and neighboring regions: Alagoas, Bahia, Federal District, Espírito Santo, Goias, Minas Gerais, Paraiba, Parana, Pernambuco, Rio de Janeiro, Rio Grande do Norte, Rio Grande do Sul, Santa Catarina, Sao Paulo and Sergipe. The area still includes the northeast of Argentina (Misiones) and the southeast of Paraguay (Department of Alto Paraná). The species grows in Rainforests on rather steep slopes, rarely on flooded sites. It occurs up to heights of 1000 m. On slopes and ridges can they form dense stands, especially over quartzite and on sandy soils. It also colonizes disturbed forest locations.

Euterpe edulis was for many years the most important supplier of palm hearts. In 1965, Paraguay exported 3205 tons of palm hearts, causing destruction of millions of palm trees. Between 1968 and 1970, Brazil exported an average of 2650 tons of palm hearts. The palm hearts were all derived from wild growing stocks. The stocks of Euterpe edulis therefore declined sharply, and use shifted Euterpe oleracea. Rather subordinate is the use of logs as lumber, roofing sheets and fruits for juicing.
