Description: Aloe parvula (Synonym = A. sempervivoides Perrier) is a thin compact and small growing species. The flowers are coral-red with yellow tips simple and hang loosely from the inflorescence (a 20-30 cm height raceme) usually one at a time, but multiple flowers per season not unusual. Aloe haworthioidesSN|620]] is another endangered species and is also one of the most attractive dwarf Madagascan aloe species along with Aloe haworthioidesSN|620]].
Habit: Succulent rosette, usually solitary or sometimes forming small groups, 10-12 cm in diameter.
Stem: Acaulescent, eventually forming a short stem with age.
Roots: Fusiform.
Leaves: 5 to 24, densely rosulate, triangular- acute, erect, expanded to spreading out, thin or a little thickened, somewhat uneven on both sides, 4-10(-12) cm long, 8-12 mm thick, blackish, dark purply blue to slate grey or pale bluish-grey, flat above, warty and covered with bristle-like hairs, somewhat keeled beneath, with many small, thin but firm, warty prickles 0.5 - 1 mm long, midrib prominent with a single row of bristle-like hairs, gradually narrowing towards the apiculate tip. Marginal teeth 1 - 2 mm long, soft to firm, horny, white, 1-2 mm apart. In cultivation, Aloe parvula retains the blue-violet leaf colour when given plenty of light, otherwise the colour is grey-green when grown in shade.
Inflorescences: Solitary, simple, rarely branched, 20-40 cm high. Raceme 5-7 cm long loose, bearing 10-15 flowers. Flower-stalks 10 cm. long, inclined.
