Lanceleaf Coreopsis

Growing Lanceleaf Coreopsis

Deadhead to extend the long bloom, or let the seed feed finches. Thrives on neglect and poor soil; rots in anything rich or wet.

Where it belongs

Lanceleaf coreopsis is native across the East, Midwest, Plains, and Texas, growing in dry prairie, sand barrens, rocky glades, and along roadsides. It is one of the species most often included in wildflower seed mixes, which means many people have grown it without knowing what it was.

The important thing about it is inverted from ordinary garden advice. It does not want compost, it does not want mulch, and it does not want watering. It wants lean, dry, sharply drained ground, and it declines in anything better.

Growing it

Full sun, dry to medium soil, in sand, loam, or rocky ground, zones 3 to 9. Eighteen inches to two feet.

The single most common way to kill it is to treat it well. In rich moist soil it grows lush, flops open, gets crown rot, and dies over winter. In gravel at the edge of a drive it persists for years.

It blooms from May into July, which fills the stretch after the spring flowers and before the summer prairie perennials, alongside foxglove beardtongue.

Deadheading extends the bloom substantially, at the cost of the seed. A practical compromise is to deadhead the first flush and then let the later heads ripen for the finches.

It reseeds where the ground is open, and individual plants are not long-lived, so the planting maintains itself as a shifting population rather than as fixed clumps.

What it feeds

The flower is a flat open daisy with an accessible center, which is the architecture that serves the widest range of insects.

Small native bees, bumblebees, flower flies, soldier beetles, and small butterflies all work it, and it is a useful pollen source in early summer. Several specialist bees collect from Coreopsis.

Goldfinches take the seed directly from the standing heads, and they time late nesting to seed availability.

Living with it

Deer generally avoid it and it is genuinely drought tolerant, needing no water after the first season.

Cut the whole plant back by a third in midsummer if it starts to look ragged. Fresh basal growth follows and often a second lighter flush of bloom.

Leave the last seed heads standing into winter. Cut back in spring.

It’s deer-resistant, drought-tolerant, easy to grow, long-blooming, and a good cut flower.
