Aloe thraskii Baker
Dune Aloe, Coast Aloe, Strand Aloe
Aloe thraskii is a tree-like succulent with pale olive-green leaves with small reddish-brown marginal teeth. It grows up to 10 feet (3 m) tall. Leaves are U-shaped in cross-section, recurved back to the trunk, sometimes even touching the skirt of old, dried leaves around the trunk. This winter-blooming species has flowers on a well-branched inflorescence that can produce 15 to 25 upright broadly-cylindrical racemes. Flowers are yellow with orange anthers, giving the flower a bi-colored look. Younger plants may have only a single inflorescence, while older plants can produce multiples.
USDA hardiness zones 9b to 11b: from 25 °F (−3.9 °C) to 50 °F (+10 °C).
How to Grow and Care
Aloe is a very forgiving plant, and a well-grown plant can be quite beautiful. However, as with all succulents, Aloe must never be 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. However, 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. When repotting 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.
