It bears single bright yellow blooms accented with maroon centers from early summer through to fall with deadheading. Slight reddish-pink tint at flush. Grows 14-16″ high by 12-14″ wide. Zone 5.
Coreopsis ‘Pink Sapphire’ – A Terra Nova introduction that is self-cleaning and bears brilliant purplish-pink blooms (with a subtle white eye) from late spring through to autumn. The flowers literally cover the contour at times and will definitely attract butterflies. Prefers a part to full sun exposure with good soil drainage. Grows 14-16″ high by 16″ wide. Hardy to zone 6.
Coreopsis verticillata ‘Sunset Strip’ – A newer introduction of Threadleaf Coreopsis with deep golden flowers accented with a dark reddish-orange eye and veining.

Hardy to zone 5.
Coreopsis ‘Summer Punch’ – Part of Terra Nova’s Punch Series, this eye-catching cultivar bears bi-colored blooms of a rich mahogany-red with golden-yellow petal tips. It has the same visual impact as those contour blooming fall chrysanthemums, but flowers all summer long. It is frost tender and should be grown as an annual in coastal BC. Grows 10″ high by 14″ wide. Zone 9.
Coreopsis x ‘Full Moon’ – This member of the Big Bang Series features very large (up to 3″ across) pale yellow blooms from early summer through to autumn. The long-stemmed flowers are excellent long-lasting cuts for the vase. In rich soils they may be prone to flopping over but you can cut it down in July and let it regrow. Grows 24-30″ high by 18-24″ wide. Hardy to zone 5.
