Agave OCAHUI

Agave OCAHUI - Ocahui agave, Agave ocahui.

Agave is a genus of evergreen perennial herbaceous plants in the Asparagaceae family, comprising about 300 species distributed across the Caribbean islands and in arid regions of North, Central, and South America. In cultivation, no more than 50 species are widespread.

Representatives of the genus form rosettes of fleshy leaves, often with spiny margins and sharp tips. The leaves can be broad or narrow, colored in gray-green, glaucous, or green shades, sometimes with variegated coloration. The stem is, as a rule, shortened. The plants are adapted to prolonged droughts, spreading outward with powerful roots, absorbing moisture from surface layers of the soil and storing it in their leaves.

Flowering occurs at 15-20 years of age, after which the plant dies. A tall peduncle emerges from the rosette of robust leaves, at the top of which an inflorescence in the form of a panicle or raceme forms, usually yellow or cream-colored. The fruits are capsules with flat seeds. After seed maturation, the aerial parts of the mother plant die back, and daughter offsets grow from the rhizomes.

Ocahui agave reaches 50 cm (19.7 in) in height and about 1.2 m (3.9 ft) in diameter as it matures. The main feature of the plant is long green fleshy leaves growing upward and having pointed tips. When the plant blooms, it produces yellow flowers.

Seeds are soaked for 2-3 hours in water or a fungicide solution, then sown to a depth of 0.5-1 cm (0.2-0.4 in) into a light, loose substrate consisting of sand, peat, and perlite, and covered with a layer of soil. The sowing is moistened from a spray bottle, placed in a mini-greenhouse or covered with film, and germinated in light, but not in direct sun at a temperature of 22-26 °C (72-79 °F). Seedlings need ventilation. It is necessary to avoid waterlogging and drying out of the sowings.

Sprouts appear within 15-25 days. The maximum germination period can be more than 40 days. After the appearance of 2-3 true leaves, pricking out is carried out into individual 6 cm (2.4 in) pots with light substrate and drainage, and after a year into 8-9 cm (3.1-3.5 in) pots. Mature specimens are repotted once every 2-3 years.

The plant can be grown indoors under good illumination. Placement on south or southwest windows with maximum access to light is preferable. In summer, keeping on a balcony or in a garden with protection from rain is possible. Large specimens in winter are kept in a cool, bright, dry room. A temperature of 20-28 °C (68-82 °F) is maintained in summer and not lower than 10 °C (50 °F) in winter.

Watering is carried out moderately, only after the soil has dried out. In winter, the frequency of watering is reduced. Waterlogging or stagnation of water at the roots is not allowed. During the period of active growth from March to August, specialized fertilizers for cacti and succulents with low nitrogen content are applied once every 4-6 weeks.

A loose, well-draining substrate with an admixture of sand, perlite, and fine crushed stone is used. Repotting is carried out once every 2-3 years or as needed. The root collar is not buried, and drainage is mandatory.

Pruning or shaping is not required. Propagation is carried out by seeds, offsets, and rhizome cuttings separated in spring or summer.
