Coneflowers are perennials that are hardy in zones 3 to 9. These easy-to-grow flowers are quite drought-tolerant, require little care and are even deer-resistant. They are frequently found in cottage gardens and bird and butterfly gardens. Several different varieties and colors other than the ever-popular purple coneflower are now available. Many of these, such as Double Decker and Harvest Moon, can be found at local garden centers. Some of the more exotic ones, however, such as Green Envy, have not yet found their way to these centers and must be purchased online or through a catalog. However you decide to purchase coneflowers, there are a few things to keep in mind in order to assure yourself of getting healthy plants.
Look for new growth on plants you are purchasing from a retailer. New growth indicates that the plant is healthy and thriving.
Do not purchase coneflowers with drooping and/or brown leaves. You might see a coneflower at a nursery that has badly drooping leaves or leaves that are actually dead. This is not a healthy plant, and you should not spend your money on it.
Determine the reliability of online plant sellers. Before ordering coneflowers from a nursery online, find out just how reliable they are. You can do this by consulting other gardeners online and asking about their experiences with the particular seller. The best way to find these gardeners is to do an online search for gardening forums and then post your question.
Order from only those catalogs that come from reputable dealers. Once again, you will have to do a little research. The best way to find out if a catalog company is reputable is to ask other gardeners in your area.
