Thelocactus bicolor [large]

Highlights

Thelocactus bicolor (also known as Glory of Texas and Straw Spine Cactus) (Britton & Rose): An easy-to-grow, globose cactus with lots of fierce spines. These green stems are lined with 8-13 ribs and have straight and curved spines of white, yellow, or red. It grows wild in Texas and northern Mexico and can reach 15.0" tall and 7.0" wide at maturity. It produces shiny, magenta flowers and occasionally grows clusters of offsets around its base. This species won the Royal Horticultural Society's Award of Garden Merit for appearance and vigor. This plant is fully rooted in a 3.5" pot.

This cactus variety will not survive a hard frost, but if there is a risk of freezing temperatures it can be brought indoors to grow on a sunny window sill or under a grow light. Cactus need bright sunlight, great drainage, and infrequent water to prevent rot. Pick containers with drainage holes and use well-draining cactus and succulent soil with 70% to 80% mineral grit such as coarse sand, pumice, or perlite. Water deeply and wait for the soil to completely dry out before watering again. Keep dry in winter.
