Description

Escobaria vivipara is a small cactus, up to 6 inches (15 cm) tall, often remaining smaller and oblong or spherical. It is densely covered in a mat of star-shaped arrays of straight white spines one to two and a 0.2 inch (5 mm) long. It flowers in yellow, pink, or purple blooms, up to 2 inches (5 cm) across.

How to Grow and Care

The Escobaria are very susceptible to rot and therefore require a well-drained soil, without any water excess or stagnation; it has been observed that the plants also suffer the environmental humidity, which should preferably remain very low (30-50%). Avoid watering during the winter, when the plant is dormant: watering Escobaria in cold environmental conditions will almost certainly lead to death of the plant. In the growing season the plants, whose growth is typically quite slow, like to perceive a significant temperature difference between night and day. The average winter minimum temperature, in general, should not fall below 42 to 46 °F (6 to 8 °C), unless individual exceptions; adult plants can withstand frosts also very intense, but only if the temperature rises again quickly.

The experienced grower knows well the difficulties of survival of this genus, certainly not one of the easiest to grow. The seed germination rate is lower than other genus and in fact other methods of propagation are preferable, as a offsets or cuttings… – See more at: How to Grow and Care for Escobaria.
