Echinocereus reichenbachii aka Classen's Cactus

Taxonomy

Echinocereus reichenbachii, commonly known as lace or hedgehog cactus, is a perennial plant and shrub in the cactus family. It is native to the Chihuahuan Desert and parts of northern Mexico and the southern United States. This cactus earned the Royal Horticultural Society's Award of Garden Merit. It is a solitary or slowly branching cylindrical cactus with up to 12 branches. With erect stems that have 10 to 19 ribs, it reaches a height of 7.5 to 30 centimetres and a width of 4 to 10 centimetres. The dark green stems are often obscured by the spines, which can be tan, brown, black, or pink, with darker tips. The elliptical or oval areoles have seven to 36 spines each. In early May to late June, the cactus produces purple or pink flowers that grow to approximately 4.5 to 8 centimetres by 5 to 10 centimetres. E. reichenbachii is cold and heat tolerant, preferring dry, well-drained soils near rock outcroppings. It is well adapted to drought and can store water within its structure. This makes it suitable for cultivation in both greenhouses and as a houseplant. In the warm summer months, potted E. reichenbachii can be moved outside.

How to care for Classen's Cactus

Difficulty

Water

Classen's Cactus does best in dry soil and should only be watered sparingly.

Soil

To ensure the health of your Classen's Cactus, it's crucial to use a potting soil that won't hold too much moisture. A soil that drains well and contains perlite or vermiculite for drainage and organic matter for nutrition is ideal. Adding a few handfuls of perlite to store-bought cactus soil is an easy way to create this type of soil mix.

Lighting

Classen's Cactus thrives in bright and direct sunlight. To ensure your plant receives enough light to survive, place it less than one foot from a window. The current weather in your area may affect the placement in your home. For example, if you live in a region that has longer and more intense periods of sunlight, then you may want to place the plant farther away from the window to avoid direct sunlight and reduce the risk of sunburn. Alternatively, if you live in a region with relatively milder temperatures and less intense sunlight, then you may be able to place the plant closer to the window for increased exposure. Ultimately, the current weather in your area should be taken into consideration when determining the best placement for your Lace Cactus.
