Many plants of the Kazakhstan flora belong to rare and endangered species, and are of special value. In Kazakhstan, rare and endangered plants were identified at the end of last century. A collection of rare and endangered plant species of the native flora in the Dendrological park and the Arboretum of the Kazakh Research Institute of Forestry and Agroforestry (Northern Kazakhstan) began to form in the 60s of the last century. The first plants were involved in the implementation of the biogeocenotic studies of natural systems in Northern Kazakhstan. Euonymus warty (Euonymus verrucosa Scop.) belongs to the family Celastraceae Lindl. and is included in the list of rare and endangered species of plants and the Red Book of Kazakhstan. The species is distributed in the mountains of Southern, Central and Southeastern Europe, in the European part of Russia. It also grows in Turkey, Iran, China, Japan and Korea. E. verrucosa is most often found in broad-leaved forests (especially oak) and mixed coniferousbroad leaved forests. Prefers fertile, lime-rich soils. Shade-tolerant mesophyte. In Kazakhstan, the species grows in the conditions of introduction in Karaganda and Almaty. Under natural conditions, the species occurs in West Kazakhstan region in the flood plain of the Ural River, occasionally forming undergrowth in oak plantings [1]. In the Dendrological park of the Kazakh Research Institute of Forestry and Agroforestry in different years for the study were recruited seeds of 24 samples from the Botanical gardens and experimental stations: Moscow, St. Petersburg, Nizhny Novgorod, Penza, Omsk, Lvov, Sochi, Ekaterinburg, Far East, Barnaul, Lipetsk and one sample of 2-year-old seedlings from Lipetsk in 1966. Sprouting was obtained from 6 samples, but later preserved plants from 5 samples. Plants were planted in the biological groups in the Dendrological park of the Kazakh Research Institute of Forestry and Agroforestry. Currently, in the dendrological Park, 7 instances of different origin grow, 4 of them are in good condition, bloom and fruit every year (2 of them under the canopy of other species, and 2 – open space). Three plants are constantly mowed down or are felled when care work is performed and grow again, but they don’t bloom. E. verrucosa is resistant to frost, doesn’t freeze in the spring and is drought-resistant. Very decorative coloring of leaves and fruits in autumn.  Average dates of phenological growth are as follows: start of growth (the swelling of the buds) was observed on April 21, opening of buds (start) – April 24, foliation – May 6, end of shoot growth – June 12-19. Flowering lasts for 15 days (June 1-14). Seeds ripen in early September (September 5). The first coloring of leaves observed on September 12, coloring lasts more than a week (until September 30). A leaf fall lasts from October 4 until frosts (the end of leaf fall unnatural). E. verrucosa under the canopy of plants has a height of 4 m (age 49 years), on free territory in the age of 42 – 3.3 m. During different years, it has been observed damage caused by allied moth (Yponomeuta cogwatellus Hb.). Thus, E. verrucosa grows well in conditions of Northern Kazakhstan and is used in protective afforestation, in the underbrush, but mainly because of its decorative effect is used in landscaping.
