Grown for their tall, showy, purple blooms, coneflowers, or Echinacea purpea, are a perennial flower that grow to a height of 2 to 4 feet tall. Loved by flower aficionados and butterflies alike, coneflowers can be found in meadows, along walkways, edging flower beds or dressing up a butterfly garden. Along with their beauty, coneflowers are often grown for their medicinal purposes — echinacea is used in many herbal extracts. To keep coneflowers healthy, they need to have the right amount of moisture.
Do not overwater coneflowers once the roots are established. According to Ron Smith, horticulturalist for North Dakota State University Extension, nothing will ruin a coneflower plant faster than too much water.
Never make homemade herbal preparations with purple coneflower unless you have studied with an herbalist.
