Portulaca

Portulaca is a genus of plants in the family Portulacaceae. The genus is commonly known as purslane. Plants in this genus are often succulent and low-growing, with small, fleshy leaves and bright, colorful flowers. They are typically found in arid or semi-arid regions and are well-adapted to drought conditions.

The most well-known species is common purslane, Portulaca oleracea. This species is native to the Middle East and India and has spread worldwide. It is often considered a weed in gardens and agricultural fields, but it is also edible and is consumed as a leafy vegetable in many parts of the world. Its leaves and stems are rich in omega-3 fatty acids, vitamins, and minerals.

Other species of Portulaca are widely cultivated as ornamental plants, particularly for their vibrant, ephemeral flowers that typically open in the morning and close in the afternoon. These are often referred to as "moss roses" or "ten o'clock" flowers. Common garden varieties include Portulaca grandiflora, known for its large, showy flowers, and Portulaca umbraticola. These plants thrive in full sun and well-drained soil, making them popular choices for rock gardens, containers, and hanging baskets. They are relatively easy to grow and are often propagated by seed or cuttings.
