Types of cacti and their reproduction
Oreocereus (Oreocereus (Berger) Ricc)
The name of the genus comes from the Greek oros - mountain: mountain cereus. The genus includes 6 species that grow in the South American Cordillera up to 4000 m above sea level (Northern Argentina, Bolivia, Northern Chile, Southern Peru).
Troll's Oreocereus (O. trollii (Kupp.) Backbg). The stem is rarely higher than 50 cm. Ribs 10-15. There are 10-15 radial spines, 1 central spines, sometimes more. The flowers are pink-red, up to 4 cm long. Homeland - South Bolivia, Northern Argentina.

Plants require bright sunlight. Watering is moderate and must be protected from dust. They hibernate in dry and cold conditions (5-8 ° C).
Parody (Parodia Speg)
The name was given in honor of the South American botanist L. R. Parodi (1895-1966). According to various authors, the genus contains from 35 to 87 species, distributed from Bolivia to northern Argentina, Paraguay and Brazil.
Snow parody (P. nivosa Backbg). The stem is spherical, up to 15 cm high and 8 cm in diameter. The ribs are arranged in a spiral. There are 15-20 radial spines, they are white with a length of slightly more than 1 cm, 4 central ones, they are white up to 2 cm long. The flowers are red up to 3 cm long. Homeland - Argentina.
During the growing season, require abundant watering. Wintering is dry and cold at a temperature of 10 ° C. Parodies are propagated by seeds and "children". Seedlings bloom for 3 years.
Rebutia (Rebutia K. Schum)
The name of the genus was given in honor of the French connoisseur of cacti R. Rébu (XIX century). According to various authors, the genus contains from 4 to 19 species, distributed from northern Argentina to northeastern Bolivia. It is close to the genus Ailoster, from which it differs in the presence of a bare flower tube (without bristles and spines).
Rebution of Marsoner (R. marsoneri Werd). The stem is 4 cm high and up to 5 cm in diameter, gives a large number of offspring. 30-35 spines, they are rusty-brown up to 5 mm long. The flowers are yellow, up to 4.5 cm long. Homeland - the north of Argentina.
Rhipsalis (Rhipsalis Gaertn)
The name of the genus comes from the Greek rhips - weaving. The genus includes 60 species of leafless epiphytic plants with jointed shoots of various forms, growing in the West Indies and South America; one species naturalized in Africa, the Mascarene Islands and Ceylon.
Rhipsalis clavate (Rh. Clavata Web). Plant with hanging whorled branching yellowish-green succulent shoots, wedge-shaped expanding from the base to the top. Areoles are located at the ends of the shoots. The flowers are white, bell-shaped. Fruits are greenish-white, berry-like. Homeland - Brazil.
Plants are sensitive to calcium and should only be watered with soft water. The root system should never be overdried. Rhipsalis grows almost constantly and needs regular feeding with a solution of ordinary fertilizers for indoor flowers. The location is bright, but protected from direct sunlight. In September - October, the plants have a short dormant period of 6-8 weeks. At this time, they are not sprayed and watered less. They usually bloom in the middle of winter. Propagated by cuttings and seeds.
Trichocereus (Berger) Ricc
The genus name comes from the Greek thrix - hair: because of the pubescent flower tube and ovary. The number of species of these stem succulents varies, according to different authors, from 40 to 75. They are distributed from Ecuador to the southern regions of Central Argentina and Chile. Most species bloom at night.
Trichocereus whitening (T. candicans (Gill.) Brett. Et Rose). The stem is erect or creeping up to 1 m high and about 16 cm in diameter, gives lateral shoots from the base. Ribs 9-11, radial spines 10-14 up to 4 cm long, central 1-4 up to 10 cm long. Flowers are white, fragrant 18-25 cm long. Homeland - Argentina.
Trichocereus purple-hairy (T. purpureopilosus WFWight.) A short, erect or creeping plant up to 20-32 cm high and 6 cm in diameter. Ribs 12. Radial spines about 20 up to 0.8 cm long. White flowers up to 21 cm long. Homeland - Argentina.
Plants require a lot of sun and warmth. Watering is abundant in spring, moderate in summer. Wintering is dry and cold (10 ° C). Propagated by seeds, cuttings, "children".
Ferocactus (Ferocactus Britt. Et Rose)
The name of the genus comes from the Latin ferox - fearless, wild. The genus includes 35 types of stem succulents, common in the southern states of the United States and Mexico.
Ferocactus powerful (F. robustus (Link et Otto) Britt. Et Rose). Large plants that form clumps of up to 1 m high and 3 m in diameter at home. Ribs 8. Size and number of spines vary greatly. Up to 14 radial spines, 4 (6) central spines up to 6 cm long, sometimes flattened, brown or red. Flowers are yellow up to 4 cm long. Homeland - Mexico.
They do not bloom in culture. Requires bright sunlight. Watering is moderate. Wintering is dry and cold (10 ° C).
Hatiora (Hatiora Br et R)
The genus is named after an English botanist of the 16th century. T. Hatiora and is represented by 4 species of epiphytic stem succulents growing on trees and in rock crevices in the southeast of Brazil.
Hatiora salicornia (H. salicornioides (Haw.) Br. Et R). A bushy plant with articulated stems. Numerous branches, straight or drooping, usually whorled. The segments are club-shaped or bottle-shaped, up to 3 cm long, 1 cm thick. Flowers are small, yellow, located at the ends of the shoots.
For the formation of flower buds in September-October, a dormant period of 6-8 weeks is required: the plant is kept cool and completely dry. After flowering, it is given a second rest until the end of May - it is kept cool and almost dry. During the period of growth and flowering, it is necessary to maintain uniform humidity. The plant prefers a bright location protected from direct sunlight (it grows well in the summer outdoors). The soil mixture should be nutritious and light from leaf, turf, humus soil and sand (1: 1: 1: 1). Better to plant in epiphyte baskets.
Propagated by pre-dried cuttings in a mixture of peat and sand, or seeds.
Cephalocereus (Cephalocereus Pfeiff)
The name comes from the Greek kephale - head. According to the American researchers of this family Britton and Rose, the genus contains 48 species growing from Florida to Brazil; in the understanding of the author of a later work on cacti K. Buckenberg, there is only 1 species in the genus, widespread in Mexico.
Senile cephalocereus (C. senilis (Haw.) Pfeiff). Columnar cactus, reaching a height of 15 m and a diameter of 40 cm. The entire stem is shrouded in long soft white hairs. Young plants have 12-15 ribs, adults - 25-30. 3-5 thorns, they are yellowish or gray up to 4 cm long. At the top of the stem, a cephalic is formed, from which pale yellowish-white flowers up to 9.5 cm long appear. Homeland - Mexico.
The plant requires bright sunlight. Watering is moderate. When watering, you need to make sure that the water does not get on the stem, protect the plants from dust. Wintering is dry and cold (5-8 ° С).
The genus name comes from the Latin words epi - na and phyllos - leaf; flowers appear on flattened stems that resemble leaves. More than 20 species spread from Mexico to the tropics of America and the Antilles; grow as epiphytic plants. They are widely used when crossing mainly with large-flowered cereus. There are currently more than 200 hybrid forms known in the culture called Fillokaktus (Phyllocactus).
Plants are kept at a temperature of 25-30 ° C in summer and 17-20 ° C in winter. Requires bright but diffused lighting. Watering in winter is moderate, in spring and summer - plentiful, with spraying. The transplant is carried out every 2-3 years in a usual mixture for cacti with the addition of peat and sphagnum. In summer, regular fertilizing with mineral fertilizers is desirable. To stimulate flowering, old shoots are cut out. Propagated by cuttings and seeds. If you artificially self-pollinate phyllocactus, you can get berries that taste like an orange and smell like pineapple.
In conclusion, I would like to note that the whole variety of cultivated cacti is not limited to the above genera. This group is extremely diverse and very decorative. If you have several different types of small cacti, you can plant them together. For example, Cereus groups well with Echinopsis and Opuntia.
Cacti combine beautifully with other succulents such as agave, aloe, milkweed, etc. The combination of cacti with stones of various shapes and colors is also interesting. Such landscapes can be quite bizarre and amazing.
In July, the main headache for gardeners is caused by problems in greenhouses: diseases of tomatoes and cucumbers begin, troubles with peppers. If you have not done prophylaxis against late blight, then it will definitely start first on potatoes, and then on tomatoes
Until recently, we distinguished groups of roses: remontant, tea, hybrid tea, polyanthus, floribunda, climbing, semi-climbing, large-flowered, grandiflora, miniature, ground cover and shrub, wild rose hips
Gymnocalycium. Zygocactus. Extreme. Leuchtenbergia. Lofofora. Mammillaria. Melocactus
Ayloster. Astrophytum. Brazilicactus
The enchanting scent of gardenia has always attracted the attention of cosmetologists and perfumers, who use its essence in the manufacture of various cosmetics. The rich, intense scent of white gardenia petals inspired Coco Chanel to create the women's perfume Chanel Gardenia. Gardenia notes are also present in Calvin Klein Eau de Toilette - Eternity Summer
