Mammillaria spinosissima rubra, known as the Red-Spined Cactus, is a striking cactus that adds a vibrant splash of colour and texture to your indoor plant collection. This compact, rounded cactus is covered in a dense layer of fine spines that glow in shades of deep red, creating a dramatic contrast against its fresh green body. Its soft, fuzzy appearance makes it an eye-catching yet gentle addition to windowsills, shelves or grouped succulent displays, bringing a touch of the desert into your home in a beautifully subtle way.
Native to Mexico, the Red-Spined Cactus thrives in bright, indirect light but will also tolerate gentle morning sun, helping it maintain its compact shape and vivid colouring. This cactus prefers a well-draining cactus or succulent compost to prevent excess moisture around its roots and should be watered sparingly, allowing the soil to dry out completely between waterings. During the winter months, reduce watering further to reflect its natural dormancy period, helping to keep the plant healthy with minimal effort.
Despite its dramatic appearance, Mammillaria spinosissima rubra is a low-maintenance, hardy plant that is perfect for beginners and those with busy lifestyles. Its compact size makes it ideal for small spaces, whether styled alone in a decorative pot or grouped with other cacti to create a striking desert arrangement.
One of the delightful features of this cactus is its occasional flowering, with small pink or white blooms forming a crown around the top of the plant during the warmer months.
