Aloe albida (Stapf) Reynolds (white-flowered grass-aloe) is a small grass-aloe native to mistbelt grassland on the Mpumalanga escarpment and adjacent KwaZulu-Natal in South Africa, typically between 1,400 m and 1,800 m elevation. It occupies seasonally wet turf that dries through the southern winter, a habitat seldom replicated in general succulent collections.

Identification
A geophytic grass-aloe forming tufts of 8 to 12 narrow linear leaves 10 to 15 cm long and less than 1 cm wide, arising from a woody rootstock. Leaves are pale green with fine white teeth along the margins, soft in texture compared with most aloes, and die back partially in winter. The inflorescence is an unbranched raceme 20 to 35 cm tall carrying small pure white tubular flowers in midsummer, a trait unusual in the genus, where red, orange, and yellow dominate. The white flower and fine-leaved tuft combination makes this species unmistakable in a mixed grass-aloe collection.
The closest confusion is with Aloe myriacantha and Aloe minima, both of which have coloured flowers and broader leaves. A. albida was reclassified into several genera through the 2010s but remains most commonly listed under Aloe; the 2013 Grace et al. revision retained it within the narrow Aloe sensu stricto.
Cultivation
This is not a species that behaves like the typical windowsill aloe. In habitat it receives summer rainfall of 800 to 1,000 mm and a dry winter with frequent mist and occasional frost. Translate that into cultivation as follows: water generously through spring and summer, reduce sharply in autumn, and keep almost completely dry from late autumn through late winter. Overwatering during dormancy kills the rootstock within one or two seasons, and it is the most common cause of failure in cultivated material.
Substrate should be more organic than the standard aloe mix, roughly 50% mineral (pumice and grit) and 50% loam-based compost, reflecting the turfy habitat. Light should be bright but not full midday sun at European latitudes; a position under light shade from late morning onward works well. Temperature tolerance extends to brief frosts to −3°C if the rootstock is dry, but sustained cold is not advisable.
Propagation
Division of mature tufts is the standard method. Lift the clump in spring as new growth begins, separate the rootstock into sections each with two or three growth points, callus for a few days, and pot into the slightly richer mix described above. Seed is also practical; fresh seed germinates within two to three weeks at 20 to 25°C, and seedlings reach flowering size in three to four years. The species is not commercially micropropagated and is encountered mostly through specialist grass-aloe collections.
Notes
Grass-aloes as a group are under-represented in general cultivation because they do not fit the "succulent" aesthetic that drives trade. A. albida is a good entry point if you want to try them. It is resilient once the seasonal watering pattern is matched, flowers reliably after its third season, and the compact tufted form suits shallow pans better than upright rosette-forming aloes.
One conservation note: the species is not formally listed as threatened, but habitat loss in the Mpumalanga escarpment grasslands is ongoing and wild-collected material occasionally appears in trade. Buy only from nursery-propagated stock.
