Dieffenbachia (Dieffenbachia), aroid family - Araceaec. The name is given in honor of the gardener of the Vienna Botanical Garden Dieffenbach (1796-1864). About 30 species of this genus are widespread in tropical America. There are many poisonous plants among them. In the West Indies, in the past, planters punished slaves with this plant, forcing them to bite off pieces of the stem. The swelling of the mucous membranes of the mouth and tongue that appeared immediately impeded speech, for which the people received the name "dumb rod".
In culture, Dieffenbachia picta is found - a shrub with variegated whole leaves, on which light green, white or yellow spots and spots are scattered. Flowers are collected on the cob. In indoor conditions it blooms very rarely.
It is very decorative, but also demanding in terms of living conditions and maintenance. Photophilous, but does not tolerate direct sunlight. The most acceptable for her is an ambient temperature of 20-25 ° C, humidity - 70-80%, clean room air. In winter, it feels best at a temperature of + 17 ° C.
In summer, watered abundantly and sprayed with warm water; in winter - much less often, but the leaves are washed regularly (after two weeks) with warm water. They are transplanted in the spring into a mixture of turf, peat soil and sand (2: 4: 1).
Propagated by apical stem cuttings, pre-dried for 1-2 days. They require a high (about 25 ° C) temperature to take root.
Many types and varieties of dieffenbachia are very shade-tolerant, and this allows them to be widely used for northern windows and low-light corners of interiors.
