Pachyphytum SALTENSE

Pachyphytum SALTENSE - Salta pachyphytum, Pachyphytum saltense.

Pachyphytum is a genus of compact leaf-succulent plants in the stonecrop family (Crassulaceae), comprising about 10 species that grow primarily in the mountainous regions of Central and Northern Mexico. These plants are adapted to bright sun and significant daily temperature fluctuations, accumulating moisture in their fleshy leaves and enduring prolonged periods of drought.

Members of the genus are perennial low-growing succulents with short fleshy stems 15-30 cm (5.9-11.8 in) long and a branched system of thin roots. The leaves are thickened, short-petioled, up to 4 cm (1.6 in) long, arranged spirally and forming dense rosettes. The surface is covered with a waxy coating with a silvery sheen, giving them a grayish-white, glaucous, or bluish-green hue, which is why the plant is often called "moonstone". The peduncles are long, bearing nodding racemes of bell-shaped flowers of pink-orange or reddish coloration, sometimes with greenish petal tips.

Flowering occurs in spring and summer. After flowering, dry multi-seeded fruits form.

Salta pachyphytum is an ornamental succulent with short stems bearing dense rosettes of oval, heavily thickened leaves. The leaf blades are fleshy, smooth, covered with a matte waxy coating that gives them a bluish-gray or greenish-glaucous hue. The tips of the leaves are slightly pointed, sometimes with a pinkish tone, especially under bright lighting. The rosette diameter reaches 10-12 cm (3.9-4.7 in).

Flowering occurs in spring or summer. The peduncle is long, curved, bearing a raceme of bell-shaped pink-red flowers with orange petal tips. The flowers stand out in contrast against the light-colored foliage and give the plant a special ornamental appeal during the flowering period.

Seeds are characterized by a low natural germination capacity not exceeding 50%. Before sowing, seeds are soaked in warm water for 12-24 hours. Sowing is carried out in a loose substrate of leaf soil and sand or in a light sandy-peat mix with a planting depth of no more than 2-3 mm (0.08-0.12 in). The soil is moistened with a spray bottle and covered with glass or transparent film to maintain constant humidity. Germination is carried out in the light, but without direct sunlight, at a temperature of 22-26 °C (72-79 °F). Daily ventilation and humidity monitoring are conducted, avoiding both drying out and waterlogging.

Seedlings appear after 15-25 days; the minimum period is about 15 days, and the maximum possible is more than 40 days. After the appearance of the first leaves, the cover is removed, and the young plants are gradually acclimated to open air and bright light. Pricking out is not required - seedlings are transplanted into individual pots as they grow.
