Description

Aloe compressa var. schistophila is a dwarf, stemless or short-stemmed Aloe with a distichous leaf arrangement. The inflorescence is unbranched with the flowers clustered at the tip. The flowers are up to 1 inch (2.5 cm) long, white with 3 brown veins.

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's essential that Aloe is never allowed to sit in stagnant water, and the plant should be carefully monitored to watch for signs of overwatering.

Aloe 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. During repotting of a larger plant, it is possible to carefully divide the root ball. Some kinds of Aloe will send off off-sets that can be potted independently.

It needs 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 cactus 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

Description: Aloe compressa is a small solitary species, without suckers, and stemless or very short-stemmed The 15-20 leaves are distichous (placed in a double row lying over each other and forming a flattened 'fan'), grey or blue green 12-15 cm long, 5 cm broad. This small aloe was first described in 1926 and is much in demand, for it is one of the very few species with two-ranked leaves, as in Aloe plicatilis and Aloe suprafoliata. The tall, unbranched inflorescence has small white flowers.
Derivation of specific name: The specific epithet compressa comes from Latin, meaning 'pressed' and refers to the laterally compressed (two-line) leaf arrangement.
Stem: None or very short
Leaves: 5-20 opposite, triangular, arranged in two lines, subercct to spreading, each 12-15(-37) cm long, 5 cm broad, 5-6 mm. thick, gradually narrowing to a rounded apex, smooth, glaucous. Margin toothed, teeth flattened up to 2 mm long, green orten with a red tip and 4-5mm apart, closely set near base, wider apart upwards.
Inflorescence: 60-70 cm tall, simple (or with one branch) with 40-60 flowers clustered at the tip. Stem very long with 15-20 white, triangular-acute, bracts. Raceme dense, almost oval, (7-8 long and 6 cm in diameter). Bracts white, 20-24 mm long, 10-17mm broad. Pedicels 1-2 mm long.
Flowers: Perianth white (or pink), 25-33 mm long straight, nearly triangular. Segments free, white with 3 brown veins, the outer ones merging into a tube in their lower half and recurved and rolled backwards above the inner touching right up to the top in an arcuate tube. The stamens and the stylus do not protrude from the flower.
