When and how Portulaca blooms
Portulaca plants thrive in warm climates and are adapted to store water in their thick leaves. They can grow in poor soils and are often found in sunny, dry spots. Some species can switch between different types of photosynthesis depending on environmental conditions, helping them survive drought. Garden types are usually grown from seed and bloom in warm weather.
