Coryphantha clava (10 seeds)

Coryphantha clava, sometimes called Escobaria, is a small Mexican cactus belonging to the Cactaceae family. It is found in southwestern North America, Mexico, and Cuba. It is a small cactus measuring 20 cm in diameter and features a multitude of small, curved needles.

This is a moderate-sized, rounded cactus. Its silhouette is compact, with a globular body. The plant has a robust and symmetrical appearance.

Its spines are short, straight, or slightly curved, and can vary in color from white, gray, and yellow to brown. Their texture is rigid, helping to protect the plant against predators.

The flowers appear at the top of the plant or on its sides. They are small and funnel-shaped, featuring vibrant colors such as yellow, orange, red, or pink. Flowering occurs mainly in spring and summer.

Coryphantha seeds are black, tiny, and measure only a few millimeters in diameter.

- Uses:

- Germination, sowing seeds:

• The best time to sow Escobaria is from June to August.
• Sow the seeds in a small jar filled with a mixture of potting soil and sand.
• Cover them with only 1 to 2 millimeters of substrate.
• Water with a hand sprayer to avoid unearthing the seeds.
• Close the jar with its lid to maintain humidity and heat.
• Leave the culture in a warm place for 2 to 4 weeks.
• Germination generally begins after 3 to 5 weeks.

- Soil type / substrate:

Coryphantha prefers a well-draining substrate, composed of a mix of cactus soil, coarse sand, and gravel. Light, airy soil prevents water stagnation.

- Exposure / sunlight:

It requires full sun exposure to promote growth and flowering. An outdoor location sheltered from the wind but benefiting from several hours of direct sunlight per day is ideal.

- Temperatures / hardiness:

This cactus can withstand temperatures as low as -8°C in a very dry environment but prefers warm climates. In winter, it must be protected from frost if temperatures drop below zero and if humidity is high.

- Irrigation / watering:

Watering should be moderate during heatwaves. During the growing season (spring and summer), water when the soil is completely dry, avoiding stagnant water. In winter, reduce irrigation to a minimum to encourage dormancy.

- Multiplication / reproduction:

Propagation is mainly carried out by seed or by dividing offsets (pups).

- Pests / diseases:

Its main pests are mealybugs and aphids, which can attack young shoots. Common diseases include root rot caused by excess water or poor drainage.
