Agave GEMINIFLORA

Agave GEMINIFLORA - Twin-flowered Agave, Agave geminiflora.

Agave is a genus of evergreen perennial herbaceous plants in the Asparagaceae family, comprising about 300 species distributed across Caribbean islands and 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 grey-green, glaucous, or green shades, sometimes with variegated coloration. The stem is, as a rule, shortened. The plants are adapted to prolonged droughts, spreading widely with strong roots, absorbing moisture from surface soil layers, and storing it in their leaves.

Flowering occurs at 15-20 years of age, after which the plant dies. A tall flower stalk emerges from the rosette of powerful leaves, atop which an inflorescence in the form of a panicle or raceme forms, usually yellow or cream in color. The fruits are capsules with flat seeds. After the seeds mature, the aboveground parts of the mother plant die off, and daughter suckers sprout from the rhizomes.

Agave GEMINIFLORA can have 100-200 linear, rigid, dark green leaves with convex margins edged in white. Flowers are 5-6 cm (2-2.4 in) on a tall inflorescence.

Seeds are soaked for 2-3 hours in a weak solution of potassium permanganate or fungicide with the addition of stimulants (SUPERthrive, HB-101, Aminozol, Epin, or Zircon), then sown to a depth of 0.5-1 cm (0.2-0.4 in) in a light, loose substrate consisting of sand, peat, and perlite, and topped with a layer of soil. Sowing is moistened with a spray bottle, placed in a propagator or covered with plastic wrap, and germinated in light, but not in direct sun at a temperature of 22-26 °C (72-79 °F). Seedlings require ventilation. Excessive moisture and drying out of sowings must be avoided.

Seedlings appear within 15-25 days. The maximum germination period can exceed 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 in good lighting. Placement on south or southwest windows with maximum access to light is preferred. In summer, keeping on a balcony or in the garden with protection from rain is possible. Large specimens are kept in winter in a cool, bright, dry room. A temperature of 20-28 °C (68-82 °F) is maintained in summer and not below 10 °C (50 °F) in winter.
