Soaking the ground at the base of the plant is the best method to encourage deep root growth. During periods of extreme heat or drought, increase water to twice a week to maintain plant health, without exceeding 2 inches per week.
LightConeflower 'Elton Knight' thrives in full sun, requiring at least 6 hours of direct sunlight daily to perform its best.

The plant is hardy and can tolerate winter cold down to -30°F but may struggle with continuous extreme heat above 85°F. The ideal temperature range for robust growth and flowering is between 60°F and 75°F.
PruningPruning Coneflower 'Elton Knight' is necessary to maintain plant health and encourage better flowering. Remove spent flowers by deadheading regularly to promote additional blooms. Cut back the plant to about 4 inches in late fall or early spring to prepare for new growth. Pruning can be done yearly, and the best time for a major prune is when the plant is dormant.
CleaningAs needed

Life cycleEchinacea purpurea, commonly known as purple coneflower, begins its life cycle as a seed, which with the right conditions of temperature and moisture germinates and emerges as a seedling. As it grows, it develops a deep taproot and a rosette of leaves at the soil surface in its first year, focusing on establishing a strong root system. In subsequent years, the plant produces sturdy, branched stems and a profusion of daisy-like flowers with prominent, cone-shaped centers from early summer to late autumn. After pollination by insects, the flowers produce seeds that are dispersed by wind or wildlife, enabling the proliferation of new plants. In winter, the plant dies back, retreating to its roots; it is a herbaceous perennial and will re-emerge with new growth in the spring. Over several years, Echinacea purpurea 'Elton Knight' can form clumps as it slowly spreads by rhizomatous growth, although it is not aggressively invasive.
PropogationPropogation time
Spring to early summer
Echinacea purpurea, commonly known as purple coneflower, is best propagated through division. This method involves separating an established clump into smaller sections, which can then be replanted to grow on their own. Typically, it's best to divide purple coneflowers in the spring or autumn when the plant is dormant, as it allows for the least amount of stress on the plant. To do this, one should carefully dig around the plant to lift the entire clump from the ground. Using a sharp knife or spade, the clump is then sliced into sections, ensuring that each section has a piece of the root system. The divisions are then replanted at the same depth they were originally growing, spaced about 1 to 3 feet apart (approximately 30 to 90 centimeters), and watered well to establish them in their new locations. This approach also helps rejuvenate older plants that may have become less vigorous over time.
