Gasteria bicolor (L.) Haw. | |
Gasteria bicolor (previously named Gasteria obliqua or Gasteria maculata) is a species of succulent flowering plant in the family Asphodelaceae, native to the Eastern Cape, South Africa.
This is a very variable species of Gasteria , common in cultivation. It grows multiple proliferous stems, all covered in untidy masses of the shiny, mottled, colourful, succulent leaves. It usually forms rosettes, but can sometimes be distichous, especially in cultivation. The leaves can also occasionally develop a keel. Each leaf has a sharp point on the tip.
The flowers generally appear on a long stem of about 30 cm (12 in), that carries tubular bell-shaped pink to orange flowers. [1] [2]
There are three major varieties, which grade into each other:
G. bicolor naturally occurs over a wide area of the Eastern Cape. In its natural habitat, it is typically found on rocky slopes and outcrops in the thicket vegetation of the region, and is particularly common around Port Elizabeth, a summer rainfall region. Its natural range overlaps with several other species of Gasteria . [6]
This species is popular in cultivation, although it is slow growing. It prefers well-drained rich soil and summer watering. Only hardy down to 5 °C (41 °F), in temperate regions it must be grown under glass in the winter months. Cultivation requirements are similar to those for other succulents and cacti. The variety G. bicolor var. lilliputana has gained the Royal Horticultural Society’s Award of Garden Merit. [7] [8]

Narcissus pseudonarcissus, commonly named the wild daffodil or Lent lily, is a perennial flowering plant.
Gasteria is a genus of succulent plants, native to South Africa and the far south-west corner of Namibia.
Agave shawii is a species of monocarpic succulent plant in the genus Agave, commonly known as Shaw's agave. It is a rosette-forming plant characterized by glossy, green leaves with toothed margins. After several years of slow growth, the plant puts all of its resources to produce a towering stalk of flowers, and then dies. The death of the flowering rosette is compensated by the growth of numerous clonal pups. This species is segregated into two subspecies, one native to the coast of southwestern California and northwestern Baja California, known commonly as the coast agave, and another native to the Baja California desert, known as the Goldman agave.
