Ferocactus EMORYI 'RECTISPINUS'

Ferocactus EMORYI 'RECTISPINUS' - Straight-spined barrel cactus, Ferocactus emoryi 'Rectispinus', Echinocactus, Ferocactus RECTISPINUS.

Ferocactus is a genus of cacti in the cactus family (Cactaceae), comprising about 30 species native to the arid regions of North and Central America.

The genus is represented by large globular and barrel-shaped cacti with heavy ribs and large areoles. The main distinction is sturdy spines, often colored red, yellow, or white. The spines are rigid, straight or hooked. Many species show a tendency to grow taller with age, transitioning into a columnar habit.

Flowering occurs in summer. The flowers are large, usually reddish, yellow, or pink, forming at the top of the plant. The fruits are oblong, fleshy, becoming dry upon ripening. The seeds are small, black or brown, rounded in shape with a glossy surface.

Straight-spined barrel cactus is one of the largest and most spectacular subspecies of Emory's barrel cactus, reaching 40-60 cm (16-24 in) in diameter in cultivation. The stem is globular or slightly elongated, with prominent ribs. The spines are exceptionally sturdy and straight; central spines reach up to 25 cm (10 in) in length, bright red or yellow-orange in color, fading over time. The radial spines are shorter and arranged evenly.

It blooms in summer. The flowers are broadly funnelform, yellow with a reddish tint at the base of the petals, up to 7 cm (2.8 in) in diameter, positioned near the crown. The fruits are fleshy, yellow-green, turning dry at full maturity. The seeds are black, lustrous, up to 2 mm (0.08 in) in diameter.

Seeds are sown on the surface of a moistened mineral substrate with the addition of fine sand. Sowings are covered with a transparent dome. Daily ventilation and maintaining a temperature in the range of 22–26 °C (72–79 °F) are required.

Sprouts appear within 7-20 days. In rare cases, germination extends to 30-40 days. Pricking out is performed after the appearance of the first spines, with seedlings carefully transplanted into individual containers and kept under diffused light.

Ferocactus is successfully grown under home conditions. It is placed in a bright sunny spot, preferably a south window or greenhouse. When cultivated in an apartment, maximum illumination and regular ventilation are provided.

In summer, a temperature of 22–30 °C (72–86 °F) is maintained; in winter, maintenance at 8–12 °C (46–54 °F) under conditions of complete dormancy is preferred. Watering is carried out after complete drying of the soil, using soft water. During the cold period, watering is halted to prevent rot.

A coarse-grained mineral substrate with the addition of sand, brick chips, and perlite is used. Preference is given to deep pots with mandatory drainage. Repotting is carried out in spring as needed. During the growing season, mineral fertilizers for cacti are applied once every 3-4 weeks. From mid-autumn, feeding is stopped. Nitrogen-rich fertilizers are not used.

Shaping and pruning are not performed. Propagation is carried out primarily by seeds, as the plant grows slowly and rarely produces offsets. The plant is recommended for both experienced and beginner cactus enthusiasts.
