ABOUT
The Echinacea purpurea 'Alba', commonly known as the White Coneflower, is a striking perennial that showcases distinct daisy-like flowers. Each flower features a prominent, cone-shaped center that is typically a soft brown or greenish color, surrounded by pure white petals that radiate outwards. These petals are long and slightly drooping, adding to the plant's relaxed and natural appearance. The foliage of the White Coneflower consists of dark green leaves that are lance-shaped with a rough texture, creating a nice contrast with the bright blooms. The leaves form a robust base for the long, slender stems that hold the flowers aloft. Together, these elements contribute to the plant's overall wildflower-like charm, which is highly admired in garden settings. The White Coneflower blooms throughout the summer, often from early to late in the season, providing a continuous display of flowers. This ability to bloom for an extended period makes it a popular choice among gardeners and a valuable source of food for pollinators such as bees and butterflies. The plant's white blossoms can also add a sense of tranquility and elegance to garden beds, borders, and naturalized areas.

WaterWhite coneflower prefers even moisture but can tolerate some drought once established. Water deeply at the base of the plant, ensuring that the soil is moistened to a depth of about 1 inch. Do this once a week during periods of low rainfall, but reduce watering frequency when rainfall is sufficient. In very hot or dry weather, increase the amount of water to help the plant cope, but always allow the soil to dry out slightly between waterings. A good rule of thumb is to provide about 1 gallon of water per plant per watering session, ensuring you do not overwater as this can lead to root rot.
LightWhite coneflower thrives in full sun, which means it requires at least 6 to 8 hours of direct sunlight per day. The best spot for this plant is in an area that receives unfiltered sunlight for the majority of the day. However, it can also tolerate partial shade, especially in the hottest parts of the day or in very warm climates. Avoid deep shade as it will limit blooming and can cause the plant to become leggy.
TemperatureWhite coneflower is a hardy plant that can survive a range of temperatures. It grows best in temperatures between 65°F and 85°F, which are ideal for vigorous growth and blooming. However, it can withstand cold down to about -30°F and heat up to 95°F without significant damage. Optimal growth occurs when the plant experiences warm days and cooler nights within the ideal temperature range.
PruningPruning white coneflower helps to promote bushier growth and stimulate more flowering. Deadhead spent blooms throughout the season to encourage continuous blooming. In the fall or early spring, cut back the entire plant to about 4 inches from the ground to maintain a tidy appearance and prepare it for new growth. Pruning can be done annually, and deadheading as needed during the flowering period.
CleaningAs needed
SoilWhite Coneflower prefers well-draining soil with a high content of organic matter. The best soil mix is a blend of garden soil, compost, and perlite or coarse sand to improve drainage. The ideal soil pH for this plant should be between 6.0 and 8.0.
RepottingWhite Coneflower does not require frequent repotting; it can be done every 3-4 years or when the plant outgrows its container. This perennial is usually content in the same spot if it's thriving.
Humidity & MistingWhite Coneflower is tolerant of a wide range of humidity levels and does well in the average outdoor humidity. Best humidity for this plant is typical garden conditions without the need for special attention.

Life cycleEchinacea purpurea 'Alba', commonly known as White Coneflower, begins its life as a seed typically sown in late winter or early spring, germinating in soil that has begun to warm. Upon germination, the plant develops a rosette of leaves close to the ground, and as it matures, it forms a sturdy stem that can grow up to 3 feet tall with lance-shaped leaves. In the first year, growth is mainly vegetative, often without blooming; flowering typically starts in the second year, with white-petaled blooms surrounding a central cone that attracts pollinators. The blooming period spans from early summer to late summer or early fall, during which pollination occurs, allowing for seed development. After flowering, as the plant enters dormancy in autumn, the above-ground parts die back, while the plant's root system, which can be quite extensive, survives the winter. With the return of spring, the White Coneflower emerges once again from its roots, ready for another growth cycle.

Spring-Early Summer
The most popular method of propagation for Echinacea purpurea 'Alba', commonly known as White Coneflower, is by seed. The best time for sowing these seeds is in late winter or early spring, ideally starting them indoors 8 to 10 weeks before the last expected frost. Seeds need to be lightly covered with soil as they require darkness for optimal germination, which usually takes 10 to 20 days at a temperature of about 70°F (21°C). After the seedlings have developed their first set of true leaves and the threat of frost has passed, they can be transplanted outdoors spaced approximately 1 to 3 feet (.3 to .9 meters) apart in well-drained soil with full sun to partial shade exposure. Over time, these hardy perennials will self-seed and spread, filling in the landscape.
