Family

Asteraceae

Botanical Name

COREOPSIS grandiflora

Plant Common Name

Large-flowered Coreopsis, Largeflower Tickseed

General Description

The specific name "grandiflora" means large-flowered, so it should come as no surprise that this lovely perennial has big bold flowers.

Large-flowered coreopsis is native to central and eastern North America. It puts forth substantial clumps of medium green foliage in spring. In late spring to early summer it becomes covered with many single golden daisies with fringed petal edges. The blooms stand erect on stiff leafless stems, attract butterflies and will continue blooming if deadheaded regularly.

Like many coreopsis, this is a sun-loving plant that does well in average to poor well-drained soil. It can tolerate partial sun but grows leggier in lower light and may require staking.

The blooms of large-flowered coreopsis glow in summer and are great for cutting. It is an easy perennial that pairs well with blue fescue, rosy Dianthus and 'Butterfly Blue' pincushion flower.
