Questions and Answers

With its red to orange center and rose-purple outer petals (ray flowers), this is the most attractive Echinacea species in Missouri and the one most widely cultivated. It grows well in light shade to full sun, and it needs average to moist soil.

A single healthy plant can produce from 25 to 50 flower heads over the blooming period, which is usually four to eight weeks in June and July with some blooms into October. Purple coneflower is excellent for cut flowers.

The yellow flowers of gray-head coneflower (Ratibida pinnata) make a nice contrast with purple coneflower.

Q: My purple coneflowers were infected with Aster Yellows disease in three different areas of my yard this year. Any recommendations on how to deal with that, or I need to remove them all and plant something different? Any plants you would recommend that are similar but not susceptible to this disease? I love the purple coneflower, so I'm very disappointed! Thanks!

A: This is from the Missouri Botanical Garden's website:
Integrated Pest Management Strategies

1. Remove diseased plants. Once a plant is infected with aster yellows, it is a lost cause since the disease is incurable. Early diagnosis and prompt removal of infected plants may help reduce the spread of the disease. Although the disease itself is not fatal to the plant, its presence makes it impossible for a plant to fulfill its intended role in the garden.

2. Plant less susceptible plant species. Controlling aster yellows is difficult. As long as infected leafhoppers are around, they can infect plants. A practical way to avoid having problems with this disease is to grow plants that are not as susceptible to aster yellows. Verbena, salvia, nicotiana, geranium, cockscomb, and impatiens are among the least susceptible plants.

3. Control insects. Vegetable growers may protect susceptible crops by using the mesh fabrics that keep leafhoppers and other insects away from the plants. Some growers put strips of aluminum foil between rows because bright reflections of sunlight confuse the leafhoppers.

4. Control weeds. Remove weeds in your lawn, garden, and surrounding areas, including plantain and dandelion that may harbor the disease.
