Description
Turbinicarpus valdezianus is a dwarf cactus with globular stems completely divided into angled tubercles and obscured by dense spines. The stems grow up to 2 inches (5 cm) tall and up to 0.8 inches (2 cm) in diameter. They have 30 or more distinctive white radial spines that spread out horizontally, forming small umbrellas on the tips of the tubercles. Unlike some other species, this species lacks central spines. Flowers are variable ranging from pinkish-white to bright pink with darker magenta or reddish-brown midveins.
Hardiness
USDA hardiness zone 9b to 11b: from 25 °F (−3.9 °C) to 50 °F (+10 °C).
How to Grow and Care
Turbinicarpus prefer to be in a well-ventilated position in full sun to maintain a good body color and spinal development.
The golden rule when it comes to watering is "never water when the compost is still damp." This is the one error that will certainly kill any plant! Watering should commence in the spring, depending upon the weather conditions at the time. The plants should initially be given a light spray to gently encourage them into growth.
These cacti can withstand high summer temperatures and benefit, providing accompanied by good ventilation. Do not be tempted to overcrowd the plants. They will be far happier with a little space to allow the air to circulate. Winter temperatures can be set as low at 44-46 °F (7-8 °C), and providing the plants are kept dry, and the humidity levels are also kept low by good ventilation on bright days.
