Description: Bergeranthus jamesiiSN|32011]]SN|32012]] is a yellow flowered ice plant relative now referred as a synonym of Bergeranthus vespertinusSN|32012]]SN|32011]], though slightly smaller. It is an almost stemless, compact, succulent with dense leafy shoots, that spread by means of offshoots with intenodes not visible, it grows to only about 5 cm tall in clumps to 12-15 cm wide with succulent, triangular, finely tapered leaves. In summer, bright yellow, daisy-like flowers cover the the plant.
Leaves: Erect at first, later more or less prostrate, shortly fused at base, narrowly acuminate, triangular in section, upper surface flat, slightly wrinkled, greyish-green with some darker translucent dots and a dense cover of wax consisting of fine platelets with sharp edges petering out in threads occasionally. Lower surface semi-cylindric at base, keeled towards tip. In their normal, natural state each leaf is only 10-30 mm long, but in cultivation they can get up to 50 mm long, 2.5-6 mm broad and 3-4 mm thick.
Flowers: 3-5 together in cymes, yellow, stalks 2-3 cm, petals in several rows, linear to narrowly lanceolate 6-11 mm long, 1.5-2 mm wide. Stamens numerous, erect.
Blooming season: Summer. Flowers are produced in succession for months.
Fruit (capsules): 5-celled, closing body a broad protrusion reaching under the covering membranes which possess a closing ledge and a low distal rim, 6-7 mm in diameter.
Seeds: Pear-shaped.

Cultivation and Propagation: Bergeranthus are easy, enormously cold hardy and rewarding plants than can be grown in pots or in the rock-garden ( the toughest seem to be B. jamesii). They can be watered year-round, water regularly from spring to Autumn but reduce watering frequency in winter, growth period is early Spring to late Summer, but is a very adaptable species that can grows opportunistically whenever the water availability and growing condition are favourable. Keep them cool, and half-shaded in summer, need full sun or light shade on the other seasons. Potted Bergeranthus look best in a heavy soil and the same is true for plants in a rockery. Requires good drainage.
Frost Tolerance: Very frost hardy and grows best where there are cold winters (it is reported to be hardy to at least -12° C if very dry). It is difficult to keep the leaves free of scars and dead leaf-tips, but the abundant flowers hide them.
Propagation: They are very easy to propagate from cuttings or (rarely) seeds.
