The inflorescence rises above the foliage in winter to spring. It is upright-branching, up to 3 foot (90 cm) tall and with dark red flowers.

How to Grow and Care
Aloe is a very forgiving plant, and a well-grown plant can be quite beautiful. As with all succulents, it is essential that Aloe is never allowed to sit in stagnant water, and the plant should be carefully monitored to watch for signs of overwatering.
These succulents are not particularly fast-growing and will only rarely need repotting. In the spring, repot Aloes that are tipping over their pots or have ceased growing. Use a fast-draining potting mix with one-third sand or pebbles. During the repotting of a larger plant, it is possible to divide the root ball carefully. Some varieties of Aloe will send off offsets that can be potted independently.
Aloe plants need strong, bright light. They can withstand full summer sun, once acclimated. In the winter, provide bright light. It prefers warmer temperatures of 70 to 80 °F (21 to 27 °C) but will survive down to 40 °F (4.5 °C). Feed with a succulent fertilizer in the summer only. Suspend feeding in the winter as the plant goes dormant. See more at How to Grow and Care for Aloe.
