Portulaca grandiflora (scientific name: Portulaca grandiflora Hook.): annual herb, 10-30 cm high. The stem lies prone or ascending, purple-red, much branched, with clusters of hairs on the nodes. The leaves are dense at the ends of the branches, the lower leaves are irregularly alternate, and the leaves are thin cylindrical and glabrous. Flower solitary or several clusters. Branch ends, 2.5-4 cm in diameter, open and closed day and night; 8-9 leaf-shaped involucres, whorled, with white pilose; petals 5 or double petals, obovate, slightly concave at the top , 12-30 mm long, red, purple or yellow-white. Capsules are nearly elliptical with cracked caps; seeds are small, many, round kidney-shaped, less than 1 mm in diameter. Flowering period from June to September, fruiting period from August to November.Growth habit Like a warm, sunny environment, poor growth in dark and humid places. It is extremely resistant to barrenness and can adapt to general soils. It is especially fond of sandy soils with good drainage. See the sun flower blooming, close in the morning, evening, and cloudy, so it has the name of sun flower and noon flower.sowing Purslane seeds are very small, about 8400 seeds per gram. They are often sown in nursery trays, covered with fine vermiculite very slightly, or only slightly compacted after sowing to ensure sufficient moisture. The germination temperature is 21-24°C, and the seedlings emerge in about 7-10 days. The seedlings are extremely thin. Therefore, if the temperature is kept high, the seedlings will grow quickly and can form thicker, fleshy branches and leaves. At this time, the seedlings can be directly placed in pots, using pots with a diameter of about 10 cm, planting 2-5 plants per pot, with high survival rate and rapid growth. Seed reproduction is the mainstay, and the self-sown ability is also strong. Sowing can be done in spring, summer and autumn. When sowing in the open field, the seeds will germinate when the temperature is above 20℃, and germinate about 10 days after sowing. The covering soil should be thin, and it can grow without covering the soil. The seedlings are planted separately, with a spacing of 5 cm × 6 cm. Need to apply liquid fertilizer several times. It can bloom in about 20 days under the condition of 15℃ or higher. Transplanting plants do not need to bring soil, and do not need to be watered frequently during the growth period. The fruit cracks when it is mature, and the seeds are easy to scatter, so it must be harvested in time.
