Gardening Questions And Answers
Botrytis cinerea causes gray mold, an infection that turns the flowers, leaves, stems and buds brown. Botrytis arises during high moisture conditions, such as heavy rainfall and standing water around the coneflower. To prevent the fungus, clear away fallen leaves and other plant debris that may harbor fungal spores.
The main blooming period for coneflowers is between June and October. Deep green foliage illuminates the growing flower stalks from below; the blossoms typically stretch higher than the surrounding leaf stalks for a brilliant show. Depending on the cultivar, coneflowers spread their petals between 4 and 8 inches wide.
Coneflowers do not grow well in heavy, clay soils that retain moisture. Too much moisture in clay soils may cause flower buds to wilt over before they start to bloom. Alternately, lack of water, particularly in full sun, may also cause buds to droop, though they tend to perk back up in the evenings.
Spacing: Coneflowers are clumping plants. One plant will tend to get larger, but it will not spread and overtake the garden via roots or rhizomes. If a plant is estimated to grow to 18 inches wide, leave 18 inches between plants. Because Echinacea establish deep taproots, you need to plant them where you want them.
Coneflowers (Echinacea purpurea) is both an ornamental and an herb. It grows in U.S. Department of Agriculture plant hardiness zones 3 through 8. Although all parts of the plant are edible, the leaves and flower buds are most commonly harvested for herbal tea. Harvest coneflowers beginning in their second year.
The plant originates from North America and was employed by the indigenous Indians. The first archaeological evidence dates from the 18th century. Included in the name Echinacea or purple coneflower are several species of the Asteraceae family: Echinacea purpurea (L.) Moench, Echinacea angustifolia DC.
Coneflowers go dormant in the winter, which means they will appear to “die back” above ground. However, if you like to have a tidy garden in the winter, you can cut back your coneflowers in the fall. Cut them back 3-6” from the ground after the stems and leaves have started turning brown and dry […]
Cutting back or pruning coneflowers is an important maintenance task because it rejuvenates the plant. It encourages new growth, increased blooms and keeps the plant from looking overgrown or untidy. Pruning is a necessary task for all gardeners because it keeps their plants healthy and gardens beautiful.
While purple coneflowers (Echinacea purpurea) are the most common, you’ll also find lots of new varieties of coneflowers in an array of happy colors, like pink, yellow, orange, red, and white. They don’t just delight for a season, either, as these are perennial flowers that will come back year after year.
