PORTULACA

PORTULACA

The portulaca genus includes about 40 species native to tropical and temperate regions. It is part of the Portulacaceae family. Among the many species, some are weeds that grow in cultivated fields, while others are flowering plants. Portulacas are annual, succulent plants that tolerate summer heat and dryness but fear and do not resist the winter cold. In temperate climates, portulacas easily seed themselves. The flowering varieties sprout all summer, producing flowers whose brightly coloured corollas close in the dark. These plants are also called “purslanes”. Their branches are generally trailing so they can be used as ground covers, or can be placed in vases as hanging plants. In any case, portulacas like full sun. Compost used for repotting must be very loose and made up of at least 50% sand that allows the soil to dry out between one irrigation and the other. Portulacas can be fed once a month with soluble ternary fertilizers dissolved in the irrigation water. They are very resistant to parasites.
