Oleander or Zokum (Nerium oleander) is a widespread species of garden and indoor flowers of the Oleander / Toy family (Apocynaceae). With an unproven origin, this evergreen shrub or small tree is found from Southeast Asia to North Africa. However, regardless of its origin, one thing must be known for sure - all its parts are toxic and regardless of its benefits in medicine, it can be very dangerous to humans and pets. This is one of the hypotheses for its name (from the Greek ὀλλύω and ἀνήρ, ἀνδρός - "I hurt / kill people"), and the other is because of the visual resemblance, although they have nothing to do with the olive tree (Olea europea). Zokum grows on straight stems that dissolve over time. It reaches a height of 6 meters, and its leaves, light green at the beginning, become dark, elliptical and elongated, growing in pairs or triplets. A representative of a monotypic genus, Oleander has a wide variety of varieties, with different colors ranging from snow white, through yellow, cream and soft pink, to deep red.

Extremely easy to look at and without serious claims of temperature and humidity, the plant needs little care to enjoy its magnificent colors.

Zocum is a big fan of direct sunlight and this, together with temperatures above 18 degrees and more water, makes the plant feel optimally good. Otherwise, it can withstand temperatures up to -10 degrees, adjusts to low humidity and different conditions.

Nevertheless, from spring to autumn, good watering is desirable, and during the warmer months, even water retention (incomplete runoff) is welcome for the flower. It is then desirable to bring the zoom out into the open. However, if it is kept in a less sunny place during the winter months, the transition to direct heating should be gradual. During the summer months and temperatures around 30 degrees, the oleander will feel best. It is favorable for spring fertilization with mineral and organic compositions, as well as periodic spraying. Given the possible size of growth, yearly pruning of the oleander is desirable.

It is transplanted with seeds and cuttings, but as seeds quickly lose their ability to germinate, they should be planted as soon as possible after their formation - under glass and at a temperature above 33 degrees until germination. However, the seed method of propagation does not allow the varietal characteristics to be preserved.
