Etymology
The specific epithet "nobilis" (pronounced "NO-bil-iss") means "notable," "distinguished," or "famous". It refers to the plant's distinguished ornamental character among cultivated aloes, as described in 1812 by Adrian Hardy Haworth.
Origin
Aloe × nobilis is thought by some to be a hybrid that results from a cross between Aloe mitriformis (Aloe perfoliata) and Aloe brevifolia. In contrast, others believe it is a cross between Aloe mitriformis and Aloe distans or between Aloe arborescens. This plant is commonly used in landscaping and is often named Aloe nobilis. It is frequently confused with Aloe perfoliata itself, but can be distinguished by its much smaller rosettes and its usually light green leaves.
Description
Aloe × nobilis is a small succulent that forms rosettes of fleshy, broadly triangular leaves with white to yellow, sharp but flexible teeth along the margins. It can grow up to 12 inches (30 cm) tall and offsets profusely, creating a mound that can reach 4 feet (1.2 m) in diameter. The fleshy, green leaves can turn orange or rose-red when stressed or in full sun.
The branched inflorescences bearing racemes of bright orange flowers can rise about 2 feet (60 cm) above the foliage in mid-summer.

How to Grow and Care for Aloe × nobilis
Hardiness: USDA hardiness zone 9b to 10b: from 25°F (-3.9°C) to 40°F (4.4°C).
Aloes are very forgiving plants. However, as with all succulents, they must never be allowed to sit in stagnant water, and the plant should be carefully monitored to watch for signs of overwatering.
Aloes are not particularly fast-growing and will only rarely need repotting. Repot plants in the spring that are tipping over their pots or have ceased growing. Use a fast-draining potting mix with one-third sand or pebbles. When repotting a larger plant, dividing the root ball carefully is possible. Some kinds of Aloe will send off offsets that can be potted independently.
It needs an intense, bright light. They can withstand full summer sun once acclimated. In the winter, provide bright light. It prefers warmer temperatures of 70°F to 80°F (21°C to 27°C) but will survive down to 40°F (4.5°C). Feed with a cactus fertilizer only in the summer. Suspend feeding in the winter as the plant goes dormant.
