'Moonbeam' is a real standout. Its pale yellow flowers are borne in great abundance above delicate, needlelike foliage and seem to blend well with practically every color we've tried. Flowers heavily from June through August, with repeat bloom till frost. 'Moonbeam' is one of those rare plants that can't be used badly. It makes a superb front-of-the-border plant but can also provide summer color in the rock garden or light up a foundation planting that is in danger of provoking yawns among passers-by. Superb with the blue racemes of Adenophora. It's one of the great perennials.
A genus of Daisy-like plants, Coreopsis is excellent for the border. Most species are native to the southeastern United States and Mexico. They are not the least fussy about soil but require full sun. Cut stems back after the first flush of flowers fade to promote a repeat bloom.

HOW PLANTS ARE SHIPPED
The size of the plants we ship has been selected to reduce the shock of transplanting. For some, this means a large, bareroot crown. Others cannot travel bareroot or transplant best if grown in containers. We ship these perennials and annuals in 1 pint pots, except as noted. We must point out that many perennials will not bloom the first year after planting, but will the following year, amply rewarding your patience. We ship bulbs as dormant, bare bulbs, sometimes with some wood shavings or moss. Shrubs, Roses, vines, and other woody plants may be shipped bareroot or in pots. The size of the pot is noted in the quick facts for each item.

I've had this variety for about 2 years now, and it outperforms most everything in my garden. Forms low, compact mounds that are absolutely covered in pale-yellow 1" flowers. Gorgeous color, and blooms for me non-stop from June to frost. Very dainty/feminine look. Place near the front to middle of your plantings for season-long color.
Mine are in full to bright part-sun, with normal midwestern soil. I wait to clip mine back in spring to help protect over winter. No deadheading necessary for me. Great low-maintenance perennial!

I have this in clumps at front of my perennial borders. It is a perennial favourite - great with blue salvia, burgundy heucheras and coleus. I love the delicate texture as marries well with bolder foliage. Once it starts blooming it goes non-stop til frost. I wouldn't be without it.

What impressed me most is the superior quality of the White Flower Farm specimens in comparison with similar plants purchased from a local nursery. The White Flower Farm plants are significantly larger with more blossoms than the local plants that are right alongside.

Planted coreopsis in 2 locations in a perennial garden. The plant stays neat with yellow flowers that contrast with its foliage. It is an eye-catching addition to the back of my yard!
Latin Name Pronunciation: ko-ree-op'sis
Merry daisies in shades of yellow and pink have made Coreopsis mainstays of the summer border. Newer colors include white with burgundy and salmon. Masses of flowers are produced for long periods, especially if plants are consistently deadheaded. These drought-tolerant perennials offer up cheerful blooms excellent for cutting and are of easy culture. There are varieties suitable for the front, middle, and back of the border, and as native Americans, they are right at home in wildflower gardens and meadows.
Light/Watering: Full sun brings out the best in Coreopsis, especially in well-drained soils. Water during drought, but Coreopsis is quite drought-tolerant once established.
Fertilizer/Soil and pH: Coreopsis is not fussy about soil, and will bloom exuberantly under a variety of conditions. Well-drained soils are best, especially in winter. Coreopsis rosea prefers an evenly moist soil (in which it may run a bit wild), although it is not a requirement. Fertilize lightly once in spring with a balanced granular formula; too much fertilizer will result in spindly growth.
Pests/Diseases: Healthy, vigorous plants under good culture are rarely bothered by insects; wash off light infestations of aphids with a forceful water spray. Diseases are also rare, especially in well-drained soils. If soils are too wet, the crowns may rot.
Companions: Butterfly delphinium (Delphinium grandiflorum) or other short Delphiniums are natural complements to yellow Coreopsis. Alliums, Daylilies, and Coneflowers are also lovely in combination with these bright daisies.
Reflowering: Daily deadheading, while onerous, will reward the gardener with almost continuous bloom. To achieve an attractive plant and possible rebloom in autumn, shear plants back by a few inches as flowering slows down in late July.
Dividing/Transplanting: Divide plants every three years in spring or early fall to maintain vigor. Please note that Coreopsis 'Moonbeam' will arrive as a tangle of roots and stems that defies attempts to distinguish top from bottom. Simply dig a wide, shallow hole and set the spidery thing inside horizontally, covering with an inch of soil. Gravity will prevail, and the plant will send roots down and shoots up.
End-of-Season Care: Do not prune back all the way for the winter, as stems left standing will protect the crowns. 'Moonbeam' will benefit from a mulch of salt hay or evergreen boughs.
Calendar of Care
Early Spring: Apply a light application of granular 10-10-10 fertilizer or side-dress with compost and organic amendments when new growth appears. Water newly planted Coreopsis regularly if spring rains are sporadic. Divide or transplant now if desired.
Summer: Deadhead daily for prolonged bloom. Shear plants back by ¼ to ½ to encourage more attractive form and possible reblooming in autumn.
Fall: Plants may be divided or transplanted now if needed. Do not prune all the way back—leave stems at 6–8″ to protect crowns through winter. Mulch 'Moonbeam' with salt hay or evergreen boughs.
