Daylilies are your best initial perennial plant investment. Daylilies are easy to grow, healthy, long lived garden plants and multiplying without much care. Hemerocallis Stella d'Oro is a diploid Daylily growing to 6-12 inches tall. It is perfect for containers. The best ever blooming Daylily and rebloomer. If you want a Daylily that blooms from May into early Fall, there is only one variety for you. Each plant produces masses of prominent golden yellow ruffled flowers, less then 3 inches across and slightly fragrant. It is one of the earliest varieties to start blooming. Flowers only last for a day, but each scape, or flower stalk, has many buds that open in a series, giving you beauty for not only days but months. Hardiness zones 3-9, (-37§C/-35§F, -5§C/25§F). It experiences dormancy. A dormant Daylily stops all vegetative growth, sets resting buds in the crown, and loses its leaves for the Winter, regardless of the climate in which it is growing. Daylilies will grow well in almost any soil, the best performance will occur in soil that is high in organic matter, drains well and has a neutral pH. Since it is such a prolific flower producer, Stella d'Oro likes to be fed with a complete and balanced fertilizer every four to six weeks. Water frequently, but not too generously at one time. Except in extreme soggy situations, extra water means more blooms and a longer season of bloom. Place in direct to indirect sun light. For the best blooming, plant in an area that receives 6 hours of sun per day.
