The Gymnocalycium grafted ‘Black Cap’ is a striking cactus that brings a bold, contemporary edge to your plant collection. Known for its almost black, deep purple top, this cactus creates a dramatic contrast against its bright green rootstock, making it a captivating feature for your home. Its architectural shape, paired with its dark, moody colouring, gives it a unique presence, allowing it to stand out on windowsills, desks or shelves.
The ‘Black Cap’ is grafted onto a resilient rootstock, helping it thrive in a wider range of conditions while making care simple, even for those new to looking after cacti. It enjoys a bright spot with plenty of indirect light and will tolerate some gentle direct sun, which can help maintain its rich colouring. The cactus prefers a gritty, free-draining compost 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 rest period, helping to keep the plant healthy with minimal effort.
Although its striking dark top is its main attraction, the Gymnocalycium ‘Black Cap’ may occasionally reward you with delicate blooms that create a gentle contrast against the bold colour of the plant, adding to its visual interest. Its compact size makes it ideal for small-space living, adding an element of sculptural beauty to your indoor space without taking up much room.
