Low-growing, fleshy plants. One is called a weed but can be used in cooking and salads. The others are grown for their brilliant flowers, on display from late spring until frost; generally, the blossoms open fully in bright light and close by midafternoon in hot weather.
P. grandiflora thrives in high temperatures and intense sunlight. Not fussy about soil. Bright-flowered types are attractive in rock gardens, parking strips, hanging baskets, or as edgings and bank covers; they don’t require deadheading to prolong bloom.Portulaca oleracea
The unimproved form is thought to have originated in India; it’s an edible weed with tiny yellow flowers and plump, oval leaves to 1 1/4 in. long. Warm weather and moisture encourage its growth. Control by hoeing or pulling before it goes to seed; don’t let pulled plants lie about, since they can reroot or ripen seed. Stems and leaves can be added to salads, soups, and sauces; improved garden strains are sold for the vegetable garden.
