Pianta a sviluppo arboreo che forma col tempo un bellissimo albero a fusto singolo. Le grandi infiorescenze gialle e rosse a forma di candelabro ne fanno una delle specie più decorative.
Scientific name: Aloe rupestris Baker
Common Names include: Bottlebrush Aloe, Rosary Vine
Origin: Aloe rupetris has a wide distribution from Natal, S. Africa, north to Swaziland and southern Mozambique
Habitat: Grows in the summer rainfall area in hot valleys among coastal forest and bushland on sandy soils or over the sun-burned hills on rocky slopes and ridges and cling along low broken sandstone ledges.
Note: A. rupestris resembles the related A. thraskii and A. excelsa, which also produce rather top-heavy rosettes atop stems clothed in their upper part with a skirt of persistent dried leaves. The racemes of A. excelsa are sloping and the plant is more common. A. thraskii has leaves that are more strongly recurved.
Aloe rupestris (A young specimen)
Description: Aloe rupestris is a robust fast growing mostly single stemmed tree aloe with very showy flowers. It can grow usually up to 3 m tall (max. 8 m tall) Offsetting forms have been favoured in cultivation.
Leaves are deep green, unspotted and bordered by red teeth and form a spiralled rosette at the stem apex in old plants, but in juvenile plants they are ranked in vertical rows.
Aloe rupestris grows well in cultivation, provided it has frost protection.
Cultivation: Easy to grow, requiring very little care. It can be grown in large containers. Always use a good quality, loamy sandy soil with plenty of drainage chips at the bottom of containers. It tolerates weekly watering in the summer; once a month, or not at all in the colder months of December and January. Can withstand long periods of drought, but they will thrive and flower more profusely if watered in the correct season. Incorrect watering, poor drainage or too much shade can lead to attack by pests and diseases. They can take a few degrees of frost in winter as well, but prefer hot summers. It grows much better outdoors in spring and summer.
Propagation: Almost exclusively by seeds planted in autumn, in trays of coarse river sand.
