The flowers of Aizoon plants are small and inconspicuous, usually white or yellow, and they bloom in the summer. The fruits are small capsules that contain many seeds.

Care Guide

Aizoon plants require minimal care and are easy to grow. They prefer well-drained soil and full sunlight, but they can also tolerate partial shade. Water the plants sparingly, allowing the soil to dry out between waterings. Aizoon plants do not require fertilization, but you can feed them with a balanced fertilizer once or twice a year. Aizoon plants are hardy to USDA zones 8-11.

Common Pests & Diseases

Aizoon plants are generally resistant to pests and diseases. However, they may be affected by aphids or mealybugs, which can be treated with an insecticidal soap or neem oil. Overwatering can lead to root rot, so make sure to let the soil dry out between waterings. Aizoon plants may also be prone to fungal diseases in humid conditions.

Habitat

Aizoon plants are native to arid and semi-arid regions, including deserts, steppes, and rocky slopes. They can grow in poor soil conditions and are often found growing in rocky crevices or on the sides of cliffs. Aizoon plants are drought-tolerant and can survive long periods of drought.
