Perennials That Bloom That the First Year

Sweet William (Dianthus barbatus), that develops in U.S. Department of Agriculture plant hardiness zones 3 through 9, might be a popular perennial flower, but just like most other perennials, the crops do not reliably bloom the first year following planting from seed. If you do not have the patience to wait three or two years on your perennials to bloom but do not wish to spend a lot of money on 2- or plants, then choose perennials that bloom the first year.

Bulbs, Corms and Rhizomes

Bulbs, corms and rhizomes are storage units capable of producing an whole plant which blooms. Bulbs like tulips (Tulipia), daffodils (Narcissus) and Asiatic lilies (Lilium spp. Oriental types) need a chilling period — a definite number of hours between 32 degrees and 45 degrees Fahrenheit — to blossom. If you reside in mild-winter regions like USDA zones 8 although 10, chill the bulbs in the fridge for 10 to 16 weeks. Other flowers, such as gladiolus (Gladiolus), are not sturdy under USDA zone 7 and need to be raised for winter. Day lilies (Hemerocallis), USDA zones 3 through 10, do not need any particular treatment to benefit you with flower after flower.

Perennials Planted From Seed That Bloom in Spring

Verbascum (Mullein) has clusters of pink flowers on spikes flourishing in spring. The blossom blooms again in autumn and goes dormant. It is a short-lived perennial, residing about three years in USDA zones 5 through 9. Snapdragons (Antirrhinum majus) are perennials in USDA zones 9 through 11 but do not withstand heat. They won’t endure in a coastal site that is cooler but could through a summer in a interior place. But they do with abandon reseed themselves. The plants grow from 12 inches high for its dwarf types to kinds that are 36 inches high for its rocket. Coreopis (Coreopsis) has yellow, daisylike flowers that bloom profusely in late spring in USDA zones 4 through 9.

Blanket flower (Gaillardia x grandiflora) does well in USDA zones 3 through 8. The flower is bright yellow, with darker gold rings on the petals or red, including a striped blanket. Maltese cross (Lychnis chalcedonica) blooms bright reddish in USDA zones 3 through 10. Verbena (Verbena) spreads with flowers held over the plant in purple, pink and red. It is hardy in USDA zones 5 through 9.

Drought-Tolerant Plants

Black-eyed Susan (Rudebekia) thrives in USDA zones 4 through 9. It is often found in the Midwest growing rampant. It is drought- and heat-tolerant, with petals around a center. Yarrow (Achillea millefolium) has horizontal heads of many smaller flowers in pink, yellow, red or white. The bush is gray-green with finely cut leaves. It develops in USDA zones 3.
