Soil: Any

This is the tallest and most robust of the C. grandiflora cultivars. At 36-48" tall and 18" wide, it is a commanding presence in the back of the garden. Its dazzling display of 3" single, golden yellow, daisy-like flowers appears in early summer. They make great cutting flowers and attract butterflies to the garden. Deadheading will dramatically prolong flowering. This English selection has unusually glossy foliage that is much more resistant to the mildew problems that can plague some Coreopsis cultivars. Easy to grow, they love full sun and any soil as long as it drains well. The clumps benefit from dividing every 2-3 years.
