Aloe Rupestris (Bottlebrush Aloe) Summary

Plant’s Physical Characteristics

Aloe Rupestris is a single-stemmed plant with large inflorescences growing above the rosettes. This succulent is known for its slightly curved blue-grey leaves with red-brown spines along the margins. When Aloe Rupestris bloomed, it produced tightly packed yellow flowers that transformed into deep orange bottlebrush inflorescences during the winter. Its flower is the showiest part of this type of succulent, maybe because of its size and vibrant color. Aloe Rupestris has a spread root system and the roots are a little fleshy compared to other aloes.  The seeds of your Aloe Rupestris are capsule-like and will typically burst or split into three parts when ripe.

Aloe Rupestris Plant Care

Generally, Aloe Rupestris care is effortless. Naturally, this type of succulent is fast-growing and grows massively. In watering, ensure it doesn’t sit on water too long. Only water the succulent occasionally to regularly, allowing it to dry properly in between watering.

Preferably used sandy loam or coarse soil mixture. Allow yours to get partial to full sunlight to grow in the best condition. This succulent prefers to stay outdoors than indoors. Feed your succulent during its growing seasons, spring to summer. You may use a specifically formulated fertilizer for cacti which is high in potassium with low dilute nitrogen.

Aloe Rupestris Plant Growth

Aloe Rupestris can be best propagated through seeds, preferably during autumn. Cuttings, leaves, and offsets might also be used to propagate, but it doesn’t guarantee a successful result. Don’t forget to allow your cuttings, offsets, and leaves to be callous for several days before replanting.

Pruning might help to keep it organized and healthy. By pruning, you could remove any dying or dead leaves and avoid the spread of any possible diseases. Aloe Rupestris don’t need too much repotting. Only repot your plant when it started to outgrow its current pot to avoid damaging it.
