Depo-Provera is an injection containing the synthetic hormone progestin which is called depo-medroxyprogesterone acetate (DMPA). Depo-Provera is a hormonal method of contraception obtained by prescription.
Though each bloom only lasts one day, the number of blooms that appear can create months of color. Many perennials, including daylilies, can tolerate a variety of growing conditions. While some cultivars of daylilies grow best in full sun, others benefit from afternoon shade.
Daylilies will grow in U.S. Department of Agriculture plant hardiness zones 4 through 9. Daylilies bloom for longer periods of time in warmer climates. A healthy daylily will give you three to four weeks of continuous blooming in Zone 4, but up to 10 months in Zone 9, according to the National Gardening Association.
