Rebutia Cactaceae Crown Cactus
Flat, fat balls with whiskery spines, spreading out into clusters. Each ball, when mature, is circled by large, wide-eyed flowers coming up from the base, often as large as the four-inch plant.
minuscula—Best-known species, with fiery red flowers.
senilis—Orange flowers with turned-back petals.
violaciflora—Rose-pink flowers.
Sedum Crassulaceae
Tender relations of the hardy garden sedums, not so numerous but equally varied.
adolphi—Rosettes of fat, yellow-green leaves, white flowers.
hintoni—Oval, grassy-green leaves covered with prickly white hairs, like clumps of tiny porcupine tails; white flowers.
lineare—Many branching, trailing stems covered thickly with needle-shaped leaves. The variety variegatum is a gem, each leaf more creamy-white than green.
