Roda was first described in 1827 by Heinrich Friederich Link and Friederich Christoph Otto. The name comes from the Latin word "echinatus" - prickly and comes from a time when most cacti are rounded to the family concerned Ehinokaktus and those with cylindrical shape of the stems - or the genus Tsereus Ehinosereus.
Genus includes ten species, among the largest of the famous round and cylindrical cactus. Close relatives are Ferokaktusite. The stems are bright green, smooth and shining, in nature reach a height of 3 meters and 1.5 meters in diameter. Ribs are numerous, straight, heavily armed. Large halo on top almost merge with each other and form a tight, billowy coating. Spikes are not numerous, their color is amber-yellow, are thick, 2.7 cm in length, in the majority of species are very strong and solid, with styliform form. In nature, plants bloom only old, at home generally do not Ehinokaktusite zatsaftyavat. The colors are yellow or dark pink, the shape of a crown is not large, 2.5 cm in diameter, are narrow, spear petals, have in a circle around the tip of the stem. In naturally pollinated by insects or small birds. Color tube is short, resnichesta covered with scales. Fruits are dry, to shatter.
Popular species are: F. viereckii, E. amoenus, E. enneacanthus, F. acifer, F. engelmanii.

Cacti of this genus are distributed in southwest U.S. and northern Mexico. Grown on clay-chalky soil, mainly in desert areas in the foothills and slopes of rocks in mountain gorges, where almost no other vegetation. In the past it was quite possible to encounter large groups of Ehinokaktusi age from 200 to 400 years, today it is difficult to detect even single copies of such age. Only in El Paso (Texas) in place works were destroyed more than 500 of these valuable plants.
Ehinokaktusite in rearing, the only problem that you may encounter is providing a place for older plants. In intense sunlight, constant flow of fresh air and moderate watering during the growth Ehinokaktusite grow relatively quickly, but is waiting to blossom is not an easy task. Most species grow well in a substrate composed of equal parts of 40% and chimovka leaflet, 30% mixture of gravel and rubble, 10% limestone additions, other aggregates. So-called "small" Ehinokaktusi (E. horizonthalonius, E. parryi, E. xeranthemoides), to be added to the substrate to 20% by volume gravel components and reducing the amount of irrigations. In winter, older plants are kept dry at 6.10 degrees. More sensitive species prefer winter temperatures 8.10 degrees.
Ehinokaktusite reproduce by seed. Semenachetata growth may accelerate, making grafts, and then again podrasnalite rooted specimens. Graft from the remaining "stalks" may serve as vegetative propagation, as readily form shoots.
Ehinokaktusite are extremely popular and widespread in collections.
