Dyckia marnier-lapostollei L.B.Sm.
Dyckia marnier-lapostollei var. marnier-lapostollei
This species is native to Brazil. It occurs in Goiás, growing in rock crevices at elevations between 3,940 and 4,100 feet (1,200 and 1,250 m).
Dyckia marnier-lapostollei is a slow-growing plant that forms a stemless, spreading, usually solitary rosette of gray-green triangular leaves covered in silvery-white scale-like hairs. The rosette grows up to 10 inches (25 cm) in diameter. Leaves are up to 8 inches (12 cm) long. They twist and curl as they recurve downward and have large claw-like recurved spines along the margins. Mature plants can send an up to 3 feet (90 cm) tall spike with orange-yellow tubular flowers scattered near the tip in summer.
The specific epithet "marnier-lapostollei (MAR-nee-air lah-pos-STOL-ee-eye)" honors Julien Marnier-Lapostolle (1902-1976), who owned the Jardin botanique "Les Cèdres" where the first specimen of the species was known to flower in 1960.
USDA hardiness zones 10a to 11b: from 30 °F (−1.1 °C) to 50 °F (+10 °C).
How to Grow and Care
Dyckias are not technically succulents, as they do not store water in their leaves like true succulents. Instead, they are xerographic and survive long periods without water by going dormant. Their rosette of thick, succulent leaves will eventually wilt, but recovery is rapid when watering is resumed.
Most plants survive in warm regions with heavy rainfall for half the year and very dry conditions the rest of the time. This makes Dyckia care slightly challenging, as getting the right balance of moisture to keep the plant happy may be difficult. The growing conditions in their natural setting should be mimicked as much as possible.
In their native region, it is not uncommon to find some forms growing on top of rocks near the water. Water and the cycle of the monsoon season are important features of Dyckia's health. They are used to rather poor soil when they grow in-ground and should be planted in a good succulent mixture.
