Considered to be one of the best wildflowers available for the garden. They’re easy to grow and have bright daisy-like flowers with a long bloom period. Bloom time is late spring through the fall. Most are very drought tolerant and do well in, poor dry soils.
This large-flowered perennial produces blooms of pure yellow. Flowers bloom through the summer into autumn if sheared regularly. Not picky about its soil, as long as it’s well drained. This xeric plant is best adapted to and will thrive in more arid climates.

Spring, Summer, Fall
Plant in spring, spacing plants 2 to 3 feet apart, depending on the variety. Prepare the garden bed by using a garden fork or tiller to loosen the soil to a depth of 12 to 15 inches, then mix in a 2- to 4-inch layer of compost. Dig a hole twice the diameter of the pot the plant is in. Carefully remove the plant from its container and place it in the hole so the top of the rootball is level with the soil surface. Carefully fill in around the rootball and firm the soil gently. Water thoroughly.
Apply a thin layer of compost each spring, followed by a 2-inch layer of mulch to retain moisture and control weeds. Water plants during the summer if rainfall is less than 1 inch per week. Stake tall varieties to keep them upright. After the first killing frost, cut stems back to an inch or two above soil line. Divide plants every few years as new growth begins in the spring, lifting plants and dividing them into clumps.
Salvia – The purplish-blue blooms of perennial salvia create a wonderful companion to golden coreopsis.
Veronica – The upright spires of spike speedwell stand in stark contrast to the lax and billowy form of coreopsis. Blue-flowered varieties look especially good with coreopsis.
Yarrow – To make the sunny perennial border sing with color, pair the golden hues of ‘Coronation Gold’ yarrow with bright yellow or gold-and-red bicolor coreopsis.
