A. tabuliforme is a succulent biennial or perennial forming a compact, flat rosette of overlapping, fleshy light green leaves. Large panicles of small, starry yellow flowers
A. canariense var. subplanum is succulent, to around 30cm tall, that forms cupped rosettes of glossy, light green, rounded leaves, tinged pink in dry or cold situations. Flowers can be produced in spring; a pale yellow flower spike emerging from the centre of a rosette. This rosette will then die, but will have formed offsets at its base to grow on
'Merry Maiden' is a perennial succulent sub-shrub, up to 60cm high, freely-branched and compact, with leaf rosettes which are dark red with green centres
'Logan Rock' is a succulent, evergreen perennial of compact, branching habit, with rosettes that are bright green in the centre, surrounded by long, narrow, pointed leaves in a very dark, bronzy, red-brown
'Blushing Beauty' is a branched, upright succulent up to 1m tall, with rosettes of glossy, light green, spoon-shaped leaves, flushed with red round the edges. Flowers can be produced in spring; a pale yellow flower spike emerging from the centre of a rosette. This rosette will then die, but will have formed offsets at its base to grow on
A. haworthii is an evergreen subshrub, each branch ending with a fleshy rosette of broad grey-green leaves. Panicles of small pale yellow or pink-tinged flowers
'Zwartkop' is a succulent evergreen perennial of open habit, with rosettes of deep blackish-purple leaves, and large panicles of small, starry, bright yellow flowers in early spring
A. balsamiferum is a succulent subshrub, up to 1.2-1.5m high, with thick, pale grey-brown branches, each crowned by a saucer-shaped rosette, 20cm across, of spoon-shaped, sticky, balsam-scented, pale green leaves with pointed tips. Flower panicles, 15-25cm long, of many pale yellow flowers appear on mature plants in late spring
'Du Rozzen' is a recently introduced cultivar that is densely-branched and forms compact mounds of rosettes. The fleshy leaves are green when young, turning to dark purple as they mature
