Plant Common Name

General Description

From midsummer to early fall, the prolific ‘Summerblaze’ offers lots of large daisies with downward-curling lemon yellow petals and dark eyes. This compact, clump-forming perennial is vigorous, fast-growing and ideal for bright sunny perennial gardens.

This hardy perennial forms clumps of basal foliage that spread slowly over time. Its sends up upright stems lined with oval, dark green leaves with deep veins. They are well-branched and become topped with lots of colorful daisies in summer. Each blossom has a dark central cone that turns yellow as the disc flowers open. The surrounding petals are bright yellow and curve downward. The flowers will continue to bloom if deadheaded and attract butterflies and bees.

Grow 'Summerblaze' in full to partial sun and average garden soil with moderate drainage. Its tall stems often require staking—especially if planted in partial shade or windy locations. Though tolerant of high summer heat and humidity, it can only withstand short periods of drought. This tall perennial is a great accent plant for the back of perennial gardens and looks especially good when planted with tall North American native grasses. Its daisies also make long lasting cut flowers.
