Greenhouses

The Palm House, built in 1982 has the height of 22 meters and the floor area of 500 m2. There are 58 species of palm trees originating from America, Africa, Asia and Europe. The highest palm is the California fan palm (Washingtonia filifera) and the oldest palm is Canary date palm (Phoenix canariensis) – 90 years.  There is gorgeous liana bougainvillea (Bougainvillea glabra) climbing along the balcony. On the hot sunny side of the balcony we can find succulent plants. In the middle of the house an epiphyte tree is exposed – a trunk with bromeliads and cacti displaying a typical rainforest habitat. Under the bananas there is a pool with fish and tortoises.
 
The subtropical house displays plants of subtropics from all over the world. First two beds consist of plants from Australia – the most common representative is eucalyptus, which in Australia grow into enormous trees and with acacia build up 95% of native dendroflora. The ground-covering plant here is Viola hederacea. The big fir-like tree is Araucaria cunninghami from the Mediterranean region. The representative of Africa is Harpephyllum caffrum. The tree with the syringa-like blossoms is Melia azedarach from East-Asia. American plants are represented with Juanulloa mexicana from genus Solanacea.
 
In the tropical house the main goal is to expose the representatives from tropical America. Some of them are grown from seeds and seedlings brought directly from expeditions. The tropical climate zone has no seasons and the changes in the amount of rainfall and temperature are minimal. We expose tropical epiphytes – bromelias and orchids, lianas and trees. Among the best-accommodated plants are begonias and Heliconia psittacorum – taken to our garden from the expedition to French Guajana in 2006. The most remarkable wooden plants are Bauhinia forficata and the representatives of Myroxylon.
 
The collection of succulents introduces plants that have become adapted to life in dry climate, bright sunlight and strong winds. In order to survive plants have their means of protection – a strong covering or cuticula, wax layer, hairs and spikes, deep ribs. Leaves can be thick and coriaceous, or indeed transformed into hair.  The stem has become the tissue that preserves and assimilates water. The homes of such plants, with minor exceptions, are Africa and Central and South America. The collection on 100 m2 consists of 600 taxa. The African cactuses are the following – Aloe, Aeonium, Crassula, Euphorbiaceae. The representatives of the New World are Cactacea, Agavaceae. The oldest plants here are the 80-year old Golden barrel cacti (Echinocactus grusonii). The succulents from the genera Allaudia and Pachypodium, originating from Madagascar, have a peculiar exterior.
