Yubi Summer Joy Scarlet is a cultivar of Portulaca oleracea (also known as purslane), that blooms in orange to red flowers with yellow centers. The flowers close in the afternoon or early evening and reopen in the morning. A heat-loving and drought-tolerant plant, Yubi Scarlet requires full sun to be at its loveliest. If you are seeking a splash of color for a window box or hanging planter, Yubi Scarlet just might be it. It can also be can be as a ground cover. Portulaca is easy to propagate by taking cuttings.
Cut a 4- to 5-inch piece of the Yubi Scarlet stem. Cut just below an area where a leaf joins the stem.
Remove the leaves and flowers from the bottom 2 inches of the Yubi Scarlet cutting.
Fill a 6-inch planting pot with equal parts peat moss and sand, well-mixed. Moisten the planting medium until water runs out of the bottom of the pot. Allow the pot to drain completely.
Poke a 1-inch hole in the soil and place the leafless end of the cutting into it. Pack the soil around the cutting and place the pot in an area that receives indirect sunlight. The cutting should root within 7 to 10 days.
Place the rooted cutting in a sunny spot where daytime temperatures remain between 75 and 95 degrees Fahrenheit and night temperatures are in the 60- to 70-degree range. Allow the top inch of soil to dry between waterings.
Apply a fertilizer solution to water the Yubi Scarlet plant two months after rooting. When the soil begins to dry, or every third day, water the plant with a mixture of 18-8-18 fertilizer and water. Dilute the fertilizer to half the strength recommended on the label. Use plain water to irrigate the plant every fourth watering.
Plant the Yubi Scarlet in its permanent location when roots become apparent at the bottom of the pot.
