Aloe perryi aka Socotrine Aloe

Aloe perryi is an evergreen succulent known as Socotrine aloe. It belongs to the Asphodelaceae family. Its native home includes Socotra and Samha, islands in Yemen. It grows on dry, rocky ground and gentle slopes. Most plants grow on limestone, though some grow on sand or granite. Its range runs from sea level to 2,950 feet [900 metres].

Plants reach about 1 foot [0.3 metres] tall. A single stem supports a dense, star-shaped rosette. Small shoots sometimes grow around the main rosette. The stem may stand upright or lie along the ground. Strong, fibrous roots anchor the plant. Each rosette holds 12 to 30 thick, tapering leaves. Leaves reach about 1.15 feet [0.35 metres] long. Their colour ranges from pale green to grey-green or red. Young leaves may show spots that fade with age. Small, light brown teeth line the leaf edges.

Flowers appear in summer on upright, branched stalks. They form dense, long clusters above the leaf rosette. The narrow tubes start red-green and turn yellow as they open. Small flower parts project just beyond each tube. The fruit is a capsule that splits to release seeds. Each capsule holds many seeds with angled edges.

This aloe grows fast and presents few problems in cultivation. It needs sun, though some summer shade suits it. Use light to medium soil that drains well. It tolerates poor ground and long dry spells. Give more water during active growth and little during winter rest. Drought stress may turn the leaves red. Sources differ on cold tolerance, but both call for warmth. LLIFLE advises frost protection; Useful Tropical Plants warns that 5°C may kill it. PFAF lists USDA zones 10–12. In cold regions, keep it indoors or in a heated glasshouse.

Rock gardens, pots and coastal sites suit this plant. Remove spent flower stalks as part of routine care. Grow new plants from seeds, side shoots or stem cuttings. Its leaf gel has a history of use for skin complaints. The plant also supplies bitter aloes for herbal medicine. No food uses are recorded, and PFAF gives it no edible rating. These medicinal uses do not establish that eating it is safe. Useful Tropical Plants reports a 2013 Near Threatened assessment. Some wild groups face risks from pests, climate shifts and heavy harvest. The evidence names no specific garden pest or disease.
