Gymnocalycium mihanovichii

**Gymnocalycium mihanovichii**, commonly known as the **Moon Cactus**, is a small, colorful species of cactus native to South America, particularly in Paraguay and Argentina. It is one of the most popular cacti in cultivation due to its striking appearance. The cactus is typically grafted onto other cacti rootstocks because it lacks sufficient chlorophyll to photosynthesize on its own. This results in vibrant color variations, including red, yellow, orange, and even pink, making it an eye-catching plant.

The most notable feature of Gymnocalycium mihanovichii is its **colorful, grafted appearance**, often mistaken for flowers due to the bright hues of the top cactus. These vivid colors come from the lack of chlorophyll, which is why the cactus must be grafted onto a green rootstock that provides the necessary nutrients for survival. It thrives in **bright, indirect light** and requires minimal watering, making it an ideal houseplant for beginners. Overwatering can lead to root rot, so well-drained soil is essential.

Gymnocalycium mihanovichii is also known for producing small, white or pink flowers that bloom in summer. Although it is primarily grown for its aesthetic value, these blooms add another layer of beauty to the plant. The cactus typically grows to about 4-5 cm in diameter and remains compact, which makes it perfect for small indoor spaces or windowsills.

In terms of care, this cactus prefers a temperature range between 20-30°C and does well in dry conditions, typical of most succulents. It can tolerate short periods of drought but should be kept away from frost or freezing temperatures.
