Gloriosa lily (Gloriosa superba) is also known as tiger claw and glory lily. They are native flowering vines to the humid, tropical locations throughout Africa. Gloriosa lilies grow to between 4 and 5 feet tall and are hardy in the USDA Zones 9 to 11. The flowers of the gloriosa lily have slender, wrinkled petals that change in color from yellow to red as the blossoms mature. Give gloriosa lilies full, to part sun, and make sure they are provided rich, moist soil.
Planting Gloriosa Lilies in Pots
Place potting mix into a suitably-sized growing container, such as a 6-inch pot, or a 1-gallon pot, until the pot is about 1/3 full of growing medium. Or mix together your own growing medium using four parts fine bark and one part coarse sand.
Sprinkle 1 tablespoon of all purpose fertilizer (such as 15-15-5) onto the surface of the growing medium and mix it into the soil thoroughly. Cover the soil and fertilizer mixture with growing medium to fill the pot halfway.
Set the gloriosa lily tubers into a bowl of water to soak for 15 to 20 minutes. Remove the gloriosa lily tubers from the bowl of water and quickly pot them up.
Place one gloriosa tuber into each 1-gallon pot. If using 10-inch pots, plant two or three gloriosa lily tubers per pot. Make sure each gloriosa lily tuber is placed lengthwise in the pots (horizontally). Cover each tuber with at least 3 to 4 inches of soil. Water each of the gloriosa lily tubers thoroughly.
Place the pots into a brightly-lit, warm area in your home. The temperature should be between 65 and 70 degrees F. The tubers will begin sprouting within 2 to 3 weeks. Keep the soil in the growing containers moist, and try to provide as much light as possible every day. You can place the pots outdoors as soon as nighttime temperatures are between 65 and 70 degrees F.
