Agave POTATORUM 'VERSCHAFFELTII'

Agave POTATORUM 'VERSCHAFFELTII' - Verschaffelt's agave, Butterfly agave, Agave potatorum 'Verschaffeltii'.

Agave is a genus of evergreen perennial herbaceous plants in the family Asparagaceae, comprising about 300 species distributed on 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 prickly margins and sharp tips. Leaves can be broad or narrow, colored in gray-green, glaucous, or green shades, sometimes with variegated coloration. The stem, as a rule, is shortened. The plants are adapted to prolonged droughts, spreading outward with powerful roots, absorbing moisture from surface soil layers and storing it in the leaves.

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

Agave potatorum is a small plant with a leaf rosette 20-25 cm (8-10 in) across. The leaves are spatulate, up to 20-30 cm (8-12 in) long, green with a red or black spine at the tip. Native to Central America.

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 covered with a layer of soil. The sowing is moistened with 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 require ventilation. It is essential to avoid waterlogging and drying out of the crops.

Seedlings emerge 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 with good lighting. Placement on south or southwest windows with maximum access to light is preferred. In summer, keeping it on a balcony or in the 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 below 10 °C (50 °F) in winter.

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

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

Shaping is not required. Propagation is carried out by seeds, offshoots, and rhizome cuttings separated in spring or summer.
