Coreopsis is a low-maintenance flowering plant suitable for beds, borders and containers. Some coreopsis plants are perennials in USDA zones 3–9, while some are annuals. Plant coreopsis in well-draining soil that receives six to eight hours of full sundaily for the best bloom production. The plant tolerates light shade, but the bloom is not as robu...
After the last frost in spring, sow coreopsis seeds outdoors in prepared soil. Don't cover the seeds; they need light to germinate. Keep the soil moist until they germinate. The soil doesn't need to be amended as long as it drains well. As they grow, thin the plants to 12 to 18 inches apart. Gardeners can get a head start on the season by sowing co...
Coreopsis can survive in less-than-ideal conditions. They're known to thrive along roadsides and in ditches. Comparatively, gardens provide practically ideal conditions, even when the soil is sub-par.
Although relatively pest-free, coreopsis is known to attract aphidsand coreopsis beetles. Treat aphids and beetle larvae with commercial insecticidal soap. Deal with adult beetles by flicking them off the plant into a jar of soapy water. When coreopsis is planted in shade, it is vulnerable to foliar diseases such as downy mildew and powdery mildew....
Coreopsis can be propagated by seed, cuttings, or division. Seeds: Seed heads form at the site of a dead or dying flower. If the seed head is already dry, pluck it and crush it between your fingers to harvest the seed, which you can plant the following spring. If the seed head has not dried, cut about 6 inches of the stem it is on and hang it upsid...
Combining both annual and tender perennial coreopsis with hardy varieties widens the array of available colors and yields some beautiful annuals that bloom nonstop from summer through fall—no deadheading needed. These make a great alternative for late-summer and fall plantings.
Salvia
Hundreds of different salvias, commonly called sage (including the herb used in cooking), and new selections for ornamental gardens appear annually. What most have in common are beautiful, tall flower spikes and attractive, often gray-green leaves. They're valued for their long bloom season, which extends right up until frost. Although not all are hardy in cold climates, salvias are easy to grow as annuals; they like full sun or very light shade with well-drained, average soil. The loose spir...
Veronica
Easy and undemanding, veronicascatch the eye in sunny gardens over many months. Some have mats with loose clusters of saucer-shaped flowers; others group star or tubular flowers tightly on straight-up spikes. A few veronicas bring elusive blue to the garden, but more often, the flowers are purplish or violet-blue, rosy pink, or white. Provide full sun and average, well-drained soil, and extend bloom time with regular deadheading.
Yarrow
Yarrow lends a wildflower look to any garden. Perhaps predictably, it's easy to care for. In some gardens, it will thrive with almost no attention, making it a good candidate for naturalistic plantings in open areas and along the edges of wooded or other wild places. Its colorful, flat-top blooms rise above clusters of ferny foliage. The tough plants resist drought, are rarely eaten by deer and rabbits, and spread moderately quickly, making yarrow a good choice for massing in borders or as a...
