There are many Bromeliads, which grow in very exposed dry places, that have developed tough, leathery leaves, and among them are the Dyckias which are popular with collectors.

DYCKIA. They are mostly natives of Brazil, but a few are to be found in other parts of S. America. Generally speaking, the Dyckias are not difficult subjects for the collector, and do not require much pampering. Most of them enjoy a slightly acid or neutral soil, but they are quite happy in leaf-mould and sand, with a little manure or any good fertilizer added. They enjoy full light conditions and can take plenty of water when the drainage is good. D. sulphured, D. rariflora, D. remotiflora, D. coccinea, D. minarum, and D. simulans are all small enough to interest the collector limited to pot culture.

All the Dyckias have stiff, spine-edged, succulent leaves. Most of the species have green leaves. The flowers range from sulphur-yellow to orange, and generally appear in spring. They produce offsets which can be easily propagated. Dyckias send out their flower spikes laterally from the side of the plant.

Dyckia sulphured. Common in most collections. The leaves are bright glossy green above, and striped yellowish-green lengthwise beneath, with hooked teeth along the edges. They form rosettes.

Dyckia rariflora. Not unlike D. sulphured, but the leaves are not as glossy. Along the edges of the leaves, slightly hooked brown-black teeth protrude.
