Introduced in the 1970's, the hybrid Stella de Oro plant was thought to be the perfect daylily. Still popular today, the Stella de Oro, or star of gold, is a hardy and dependable blooming flower. The flowers are shaped like trumpets, have a light fragrance and spread year after year. Even though the bright yellow flower only lasts for a day, the plant will bloom for months by producing buds all season. This is a very low-maintenance plant that is pest and drought resistant. The tall flowers make for excellent edging and border plants.
Choose a location that has full sun to partial afternoon shade. Daylilies planted farther north need the most sun. Do not plant in areas where water pools after a hard rain or too close to trees and shrubs as the flowers will have to compete for water and nutrition. Planting should be planned for early spring, as soon as the ground can be worked.
Prepare the flower bed by turning the soil over to a depth of 10 inches. Remove all grass, weeds and stones from the soil. Place 3 inches of compost over the soil and work it in with a shovel. Rake the soil out smooth.
Dig holes in the bed, 12 inches apart, 2 inches deep and 1 inch wider than the tuber. Place the tubers in the holes with the roots facing down and bud facing up.
Fill in the holes with soil and water the bed thoroughly. Water every other day for longer periods of time rather than every day for a short time. Keeping the soil moist will ensure more flower blooms.
Spread a 10-10-10 fertilizer on the flower bed when you start to see the the seedling pop out of the ground. Water the fertilizer in well and try not to get it directly on the new seedlings or it may burn them. Fertilizing can be done once each spring to help the flowers get started.
Mulch the flower bed to help retain moisture during the heat of the summer. It will also keep away weeds and keep the soil warmer throughout the winter.
