Gymnocalycium horstii (Spider Cactus) D5

Gymnocalycium horstii is a species of cactus native to Paraguay. It is a succulent, globular plant, with a diameter of about 5-7 cm. It has a matte green color, and on its surface there are prominent tubercles from which long and strong spines grow. The flowers, which appear at the top, are usually white or pale pink, with a slightly pink shade in the center.

This plant is a popular choice for cactus collectors, due to its compact and beautiful shape, as well as its attractive flowers.

It grows well in well-lit spaces and requires moderate watering. It is important to mention that, like other cacti, Gymnocalycium horstii prefers well-drained soil to avoid root rot. Also, the plant needs a resting period during winter, during which watering should be reduced.
