Native to Texas and Mexico, this slow-growing plant is spineless (it has no prickles). It is so named because it resembles the skeleton of a sea urchin.

Star Cactus seeds are black and shiny, measuring 2 millimeters in diameter.

The flower of the Astrophytum asterias is large, reaching 4 to 7 cm in diameter, and is cup-shaped. It is distinguished by delicate petals that can be yellow, white, or orange. Flowering takes place in spring and early summer.

The Star Cactus: A geometric feat of nature

Sowing Astrophytum seeds from Ethnoplants allows you to discover one of the most fascinating specimens in the Cactaceae family.
This cactus is distinguished by its remarkable natural symmetry: its globular structure, virtually spineless and divided into regular ribs, creates a perfect star shape.
It is a centerpiece for any collection, prized by succulent enthusiasts for its minimalist elegance, slow architectural growth, and unique geometric precision.

An iconic species of the Mexican highlands

Native to the arid lands of Mexico, the Astrophytum is a fascinating plant, perfectly adapted to desert environments.
In its region of origin, this species holds a strong symbolic place within local traditions.
Today, it is primarily admired by botanists and collectors worldwide for its exceptional resilience and graphic appearance that evokes the raw beauty of the arid landscapes of Central America.

- Germination and Sowing:

• The most favorable period to sow false peyote is from June to mid-August.
• Sow the seeds using the "smother" method (airtight) in a food container filled with a mixture of equal parts fine potting soil and sand.
• Spray water over the top just enough to dampen the substrate.
• Close the lid.
• Place the container in a warm spot at a temperature of approximately 35°C in a bright room.
• Once the seeds have germinated, wait until the seedlings are 1 cm high before transplanting them into separate pots.

- Substrate and Soil Type:

This small cactus grows very well in sandy, mineral soil composed of 30% potting soil. Ensure the bottom of the pot is well-drained with small pebbles or clay beads.

- Watering and Humidity:

It does not need much water. Once a week in the summer is more than enough, and every 10 days during the winter period.

- Exposure and Light:

This round and symmetrical plant requires a lot of bright light; it should be placed in full sun. Regarding artificial lighting, HPS bulbs or MH horticultural lamps are preferred.

- Temperature and Hardiness:

The star cactus grows very well when temperatures range from 15°C to 45°C. It is very sensitive to cold and will not survive freezing temperatures. Therefore, it must be brought indoors during the winter.

- Propagation:

The only way to reproduce this cactus is through seeds; unfortunately, it cannot be grown from cuttings.
