Stella d’Oro daylilies, or Hemerocallis "Stella de Oro," are flowering perennial plants that have deep golden-yellow, trumpet-shaped blooms. Stella d’Oro means "star of gold." These daylilies bloom in late spring and early summer, with repeat blooming through the summer and fall. Plant your Stella d’Oro daylilies in partial shade or full sun. These flowers are hardy in U.S. Department of Agriculture (USDA) Plant Hardiness Zones 3 through 9, so they can tolerate temperatures down to -40 degrees F. You can plant your Stella d’Oro daylilies in early spring, as soon as the ground thaws enough to work.
Things You’ll Need
- Organic compost (optional)
- Stella d’Oro daylily plants
- Organic mulch
- All-purpose flower fertilizer
- Loosen the soil at the planting site with a pitchfork. Break up any large clumps. You can add some organic compost to the soil if the soil is poor.
- Dig planting holes that are the same depth as and 4 inches wider than the containers. Space plants 18-to-24 inches apart.
- Place the root balls into the holes and backfill the soil. Tamp the soil down around the roots to eliminate any air pockets in the soil.
- Spread a 1- or 2-inch layer of organic mulch around the plants to retain soil moisture. Water the daylilies once per week to encourage more flowers.
- Feed your Stella d’Oro daylilies with an all-purpose flower fertilizer once every year in early spring. Follow the dosage instructions on the package.
Tips & Warnings
You can propagate your Stella d’Oro daylilies by dividing the root ball.
Pinch off spent flowers throughout the summer to encourage re-blooming. Clip old stalks and remove any brown leaves.
Although Stella d’Oro daylilies are adaptable to most kinds of soils, avoid planting them in water-logged or heavy soils.
