Bright upright plants, coneflowers are a North American perennial in the Daisy family (Asteraceae). They grow 2 to 4 feet in height with dark green foliage. They are fast growers and self-sow their seed profusely. These midsummer bloomers can flower from midsummer through fall frost! Coneflowers have raised cone-like centers (hence, the name) which contain seeds that attract butterflies. Leave the seed heads after bloom and you’ll also attract songbirds!
