Some Perennial flower-
Blanket Flower
Blanket flower (gaillardia) is a drought- and heat-tolerant perennial wildflower that provides long-lasting color
in a sunny border with poor soil. In red, gold, or brown, its
daisy-like, 3-inch wide, single or double perennial flowers bloom
through the summer and into the fall. Although often short-lived, it is easy to grow and will flower the first year from seed.
-
Veronica
The 7-inch spikes of veronica bloom atop 12- to 24-inch plants in shades of blue or red from early summer through fall.
In the North, veronica prefers sun, but it likes a bit of shade in the
South. Plant these perennial flowers at the front of the bed.
Tall Garden Phlox
Phlox
paniculata -- garden, tall, or border phlox -- grows 3 to 4 feet tall
and bears large trusses of fragrant perennial flowers from summer to
early fall. It's an old-fashioned favorite that has few rivals for its
color display and light, sweet fragrance. It's well suited to the back
of the garden and cottage gardens.
Russian Sage
Suited to larger gardens,
this 3-foot-wide by 5-foot-tall perennial creates clouds of blue
flowers in late summer. Russian sage likes sun, and is tolerant of
drought and heat. Plant these perennial flowers at the back of the bed and give it room to grow.
Perennial Sage
Hybrid perennial sage, a relative of the herb garden
favorite, combines 18-inch spikes of blue, purple, or white perennial
flowers with attractive gray-green foliage. Plant sage in the front or
middle of the border in a sunny spot. The variety shown here, 'May
Night', is both cold-hardy and showy.
Asters
A
staple of the fall garden, asters burst forth with their star like
perennial flowers in late summer and autumn. Bloom colors include rich
pinks, blues, purples, and ruby reds. They can soar to 5 feet, depending
on the species, and are excellent for beds and borders as well as for
cutting to bring indoors.
Astilbe
The feathery plumes of astilbe rise above fern-like foliage for a month or more in late spring and early summer. Available in shades of pink, white, and red, astilbe is ideal for shady, moist spots. Plant a swath of these 2- to 3-foot-tall perennial flowers for a memorable display year after year.
Siberian Iris
Siberian
iris adds color
to flowerbeds in early summer, and vertical accents all summer long.
Like most irises, these are moisture-loving plants, but once established
they will tolerate dry soil. The blooms appear atop leafless stems
rising from the 2-foot-tall grass-like foliage. Colors include white,
blue, yellow, and violet, with many bi-colors. In addition to
brightening the garden, Siberian iris provides a steady supply of cut
flowers.
Peonies
Often
sweetly fragrant, the peony is a very long-lived perennial flower that
forms 2- to 4-foot-tall clumps in shrub-like bunches. Its numerous
varieties offer a wide range of colors -- almost every shade except blue
-- with some bi-colors, and blooming periods from late spring to early
summer.
Daffodils
Daffodils
are dependable perennial bulbs, blooming in early, mid, or late spring,
depending on the cultivar. The flowers have a central trumpet (corolla)
-- the length varies among cultivars -- surrounded by a collar of
petals (perianth) that can be a different color. Colors
include yellow, orange, white, red, and peach. Some are fragrant. The
strappy, narrow leaves emerge before the flowers do and are a little
shorter than the flower stalk.
Threadleaf Coreopsis
Coreopsis comes in a wide range of sizes and several colors.
The thread leaf varieties of these perennial flowers -- like 'Moonbeam'
and 'Zagreb' -- produce blankets of small daisy-like flowers all summer
long in yellow or pink, with soft, ferny foliage. (In hot areas, flower
production may slow temporarily.) Grandiflora varieties ('Early Sunrise'
is one popular version) produce larger orange-yellow blooms. Give this
plant a starring role in the middle of the bed.
Pincushion Flower
Pincushion
flower, or scabiosa, serves up dainty blue perennial flowers all summer
and into fall, making it one of the longest-lasting bloomers in the
perennial bed.
It likes sun or partial shade, and is best at the front of the bed. The
foot-tall variety 'Blue Butterfly' stands up to heat best.
Black-Eyed Susan
Black-eyed
Susan is truly an American icon. Blooming from midsummer until frost,
its orange or golden yellow blooms just keep coming. The variety
'Goldsturm', shown here, tops out at about 2 feet, making it perfect for
the middle or back of the bed. It loves sun and is drought-tolerant.
Asiatic Lily
For reliable summer color,
you can’t beat Asiatic Lilies. These bright charmers are available in a
cheerful variety of yellow, orange, red, white, cream, rose, purple,
and bi colors. Asiatic Lilies grow easily from bulbs planted in the
spring or fall.
They require a sunny spot with well-drained soil, but otherwise, are
undemanding. Plus, each year these vigorous plants form bigger and
better clumps that you can dig and divide to share with friends. Asiatic
Lilies grow 24-36 inches tall and make great cut flowers.
