Not many perennials will bloom year around but here are some of my favorite long blooming perennials:
Campanula (Bellflower) Bloom Span: 2+ Months; There are many species of Campanula or Bellflowers, all easy to grow and relatively long lived. They perform best in areas with cooler summers or in partial shade where the summers are more intense. Most Bellflowers will readily self sow. If they start to look tired and ragged after several blooms, shear or mow them down to a few inches and they will grow back fresher. GOOD CHOICES: Campanula carpatica 'Blue Clips' or 'Blue Chips', C. c. 'White Clips' or 'White Chips'

Centranthus (Red Valerian) Bloom Span: 3-4 Months; Centranthus prefers dry, lean soil, but it blooms longer in cooler climates. In intense heat it will bloom in spring and again as it feels up to it, throughout the summer. Centranthus rarely grows true from seed and is best propagated by cuttings. To be certain of what color you are getting, buy the plant while it is in flower. The plants don't live longer than about 5 years and they resent being divided or every relocated. GOOD CHOICES: Centranthus ruber 'Albus'.
Coreopsis (Tickseed) Bloom Span: 3+ Months; Coreopsis are undemanding plants, but short lived. Either allow them to self-seed or divide the plants every 2-3 years and replant the newer, outer sections. Flower buds form all along the stems, making deadheading a time consuming challenge. Once the initial buds have completed blooming, sheer the plants back by 1/3 to encourage new flower buds. GOOD CHOICES: Coreopsis verticillata 'Zagreb', C.v. 'Golden Showers', C. grandiflora 'Early Sunrise'.

Corydalis lutea (Fumewort) Bloom Span: 4 Months ; Corydalis' ferny foliage and delicate flowers belie its fortitude. This is a plant that prefers partial shade and well drained soil and will find a home in cracks in rocks, on slopes in woodlands and along paths. Once established, Corydalis self sows wherever it can. However it can take years for the seed to germinate, so trying to start your own plants can be frustrating. GOOD CHOICES: You will probably only find the species of C. lutea
Dianthus (Pinks) Bloom Span: 2+ Months; While most Dianthus have a long natural period of bloom, many will rebloom with some deadheading. Several varieties are also evergreen and make nice edging plants. Dianthus does well in any well-drained soil, though it prefers a slight alkalinity. They don't tend to live very long and should be divided or seeded regularly. GOOD CHOICES: Dianthus gratianopolitanus 'Bath's Pink', D. g. 'Cheddar Pink', D. deltoids (Maiden Pink).

Dicentra formosa & Dicentra eximia (Fringed Bleeding Heart) Bloom Span: 3+ Months
Unlike the common bleeding heart (D. spectabilis), cultivars of the fringed species will repeat bloom for most of the summer. D. formosa is a western native while D. eximia is able to handle the heat and humidity of the eastern U.S. The fringed bleeding hearts are smaller plants than D. spectabilis and the flower is not as pronounced a heart shape, but the gray-green ferny foliage and abundance of flowers make it a prize. Most self-seed. GOOD CHOICES: 'Alba' has a pure white flower.

Echinacea purpurea (Coneflower) Bloom Span: 2-3 Months; Having a long bloom period is just on of Echinacea's many attributes. Coneflowers are extremely drought tolerant, attract birds and butterflies and the intense color adds punch to any garden. The tall stalks are self-supporting, unless they've received so much water they become floppy. They require good drainage and full sun. Deadheading will prolong the bloom period. Although Echinacea is slow to spread, division is the best way to get the cultivar you want. The seed heads can be left on through the winter and will provide a treat for neighborhood birds. GOOD CHOICES: Echinacea purpurea 'Magnus", E.p. 'Fragrant Angel', E. "Art's Pride'.

Gaillardia (Blanket Flower) Bloom Span: 3-4 Months; Gaillardia's yellow petals around a burgundy center are impossible to ignore in a garden. All they ask is full sun and they will keep on blooming all summer. Too mush shade and the stems begin to flop. In most cases, deadheading is not necessary for continual bloom, but it can make the plants look tidier. Gaillardia is another short-lived perennial and should be divided or seeded often. GOOD CHOICES: Gaillardia x grandiflora, Gaillardia 'Goblin' (dwarf), G. 'Burgundy', G. 'Monarch'.

Kniphofia (Red Hot Poker) Bloom Span: 3+ Months; The spiky, bottle-brush flowers of Kniphofia are beacons for hummingbirds. Although they look like tough customers, Kniphofia actually requires a bit of winter protection in cooler zones. They are also a bit fussy about liking moist conditions in the summer, but well-drained soil for the winter months. Full sun is generally necessary for ample blooms. Kniphofia does not divide or transplant well, although you can usually get away with removing and replanting the young side shoots of the plants. GOOD CHOICES: Any of the hybrids. Kniphofia ''Primrose Beauty' is especially hardy.

Liatris (Gayfeather, Blazing Star) Bloom Span: 3 Months; Liatris are easy to grow and texturally unusual. The thin, spiky leaves jut off the stems all the way to where the rosy-purple flower spikes begin. Unlike most spiky flowers, Liatris blooms from the top down. Liatris can handle just about any type of soil, but the richer the soil, the more likely they'll need staking. They'll grow in full sun or partial shade. Liatris is long lived and doesn't often require division. They will self-seed, but generally don't take over. GOOD CHOICES: Liatris spicata (Spike Gayfeather) comes in white, pink and shades of purple.

Nepeta (Catmint) Bloom Span: 2-3 Months; Most people think of Nepeta as catnip (Nepeta cataria), a somewhat weedy garden plant. But there are many excellent ornamental Nepetas that will bloom throughout the summer, if deadheaded. Most have some shade of blue-lavender flowers and gray foliage. They are very drought tolerant and make a nice substitute for lavender, in areas where lavender won't thrive. Although not as attractive to cats as catnip, you may still find a cat or two rolling around in your plants. GOOD CHOICES: Nepeta 'Six Hills Giant', Nepeta x faassenii 'Dropmore' (Sterile and doesn't need deadheading)

Rudbeckia (Black-eyed Susan) Bloom Span: 3 Months; Rudbeckia are at home everywhere and many are native to various parts of North America. They prefers well-drained, somewhat lean soil and full sun. Deadheading will prolong bloom and cut Rudbeckia flowers will last a long time in water. With their flat landing pad petals, they are attractive to butterflies and the seeds will be eaten by the birds during the winter. Relatively long lived, Rudbeckias can be easily multiplied by division.
GOOD CHOICES: Rudbeckia fulgida 'Goldsturm"

Scabiosa (Pin Cushion Flower) Bloom Span: 3+ Months; Scabiosa is a unique looking plants with a low growing rosette of narrow leaves and a profusion of gangly stems topped by pincushion flowers. They are relatively easily grown in average soil and full sun. Deadheading is a must for long bloom and general appearance. Divide plants every 3-4 years.
