(Portulaca oleracea) Purslane is a delicious and versatile green that practically grows on its own without any help at all! The plants love full sun and lots of heat but will produce more flowers when offered some afternoon shade. Purslane is thought to be a good companion plant for a number of crops, including corn. Purslane is a tender perennial that self-sows easily. The plants require well-drained soil and prefer full sun. Start seeds indoors six to eight weeks before last frost date, or surface sow outdoors once all chance of frost has passed. Ideal germination temperature is 70-80F. Sprinkle seeds onto moist soil, pressingly gently into the soil, as the seeds need light in order to germinate. Seeds germinate in 10-14 days. Space plants 8-12 inches apart. Harvest before blooming to limit plants' spread.
