Suggested uses include houseplant, conservatory plant and patio plant.
About
Gasteria nitida var. armstrongii is a clump-forming, rosette-forming succulent in the Asphodelaceae with thick, tongue-shaped, mottled leaves. It remains evergreen and produces basal offsets that form compact clumps. Plants flower in the UK from March to May. The foliage is the main ornamental feature outside the flowering period.

In the garden
Gasteria nitida var. armstrongii sits within the Asphodelaceae and presents as a compact rosette that slowly spreads by offsetting. Leaves are thick, tongue-shaped and mottled, staying evergreen through the year; flowering in the UK occurs from March to May. Its compact habit makes the leaf structure the primary garden interest for much of the year. Place the plant where it receives full sun or partial shade on a south-, east- or west-facing site with shelter from strong winds. Use a free-draining mix based on loam and sand and avoid waterlogged positions; the plant performs on acid to neutral soils provided drainage is good. The UK hardiness rating H2 translates to half-hardy, so it is suited to indoor culture, a conservatory or a sheltered patio over winter rather than exposed beds. For containers, position where the thick leaves catch light and provide regular but moderate watering, allowing the compost to dry between waterings to maintain well-drained conditions. The clump-forming habit suits pots, tub plantings and conservatory displays where offsets can be left to form tight groups that show the mottled leaf surface to best effect.
