Crinum
Crinum
Family Amaryllidaceae. Native to South Africa. There are about 100 species in the wild. Crinum is a magnificent flowering plant more suitable for cultivation in greenhouses and conservatories than in apartments. Not only because the plants reach enormous sizes — the main reason is the need for a cool winter dormancy. They usually flower in July - September.
Crinum Moorei - Crinum moorei is a perennial bulbous plant. The bulb is about 15 cm in diameter, spherical in shape, buried halfway in the substrate. Leaves are strap-shaped, light green, with a closed sheath forming a pseudostem. Leaves are about 70 cm long. The scape is up to 50 cm long, with an umbel of 6–12 flowers. The perianths are bell-shaped, with pointed tips to the segments, about 8 cm in diameter, pink or white in color.
Crinum Powellii - Crinum powellii is a perennial bulbous plant. The bulb is about 20 cm in diameter, spherical in shape, buried halfway in the substrate. Leaves are strap-shaped, light green, up to 1 m long, with a closed sheath, forming a rosette. The scape is up to 1 m long, with an umbel of 6–12 flowers. The perianths are bell-shaped, with pointed tips to the segments, up to 15 cm in diameter, bright pink, red, and white in color.
Temperature: During the growing season, optimal 17-20°С. During dormancy keep at 8-10°С and dry.
Light: Bright, diffused light. Shade from direct sunlight.
Watering: Abundant during flowering — the soil should remain moist at all times. However, avoid overwatering; Crinum, like all Amaryllidaceae, is sensitive to excess moisture. During dormancy watering is almost stopped, or rather done very rarely so that the fleshy roots do not dry out completely.
Fertilizer: Once every two weeks with a liquid fertilizer for flowering houseplants, diluted to the concentration recommended by the manufacturer. Begin feeding as soon as young leaves appear and stop when the last flowers fade.
Air humidity: In summer, leaves are occasionally misted and wiped with a damp sponge.
Repotting: About every 3–4 years, during the dormancy period. Soil: 2 parts clay-loam turf, 1 part leaf mold, 1 part humus, 1 part peat and 1 part sand. Add pieces of birch charcoal to the soil. Choose the largest container possible; for mature plants these are usually tubs.
Propagation: By daughter bulbs in summer. When separating bulbs try not to damage the roots. Treat cuts with crushed charcoal. Young plants flower only in the 3rd–4th year.
