Field Chickweed

The Story

Plant Bio

Cerastium arvense, commonly called field chickweed, is a low-growing herbaceous perennial that forms creeping mats of soft, grey-green foliage from slender rhizomes. In spring and early summer, terminal clusters of notched white flowers rise just above the downy leaf canopy.

The species is distinguished by five deeply two-lobed petals that create the appearance of ten distinct heart-shaped petals on each bloom. Unlike aggressive annual weeds in the same genus, this perennial native forms a stable, drought-tolerant groundcover across gravelly, well-drained soils.

Uses & Benefits:

Forms a dense ground-hugging carpet topped with white split-petaled spring flowers.

Stabilizes sunny dry slopes and gravel edges where topsoil is thin.

Provides nectar for solitary bees, mining bees, and syrphid flies.

Planting

How to Grow

Select a planting site in full sun to light shade with sharply draining sandy, loamy, or rocky soil.
Space plants 12 to 18 inches apart to allow room for the stoloniferous mats to spread.
Water lightly after planting until roots establish, after which rainfall is usually sufficient.
Trim spent flower stems back to the main foliage carpet in mid-summer to maintain shape.

Pro Tip

Shear the spent flowering stems back to the foliage mat immediately after peak bloom to prevent self-seeding and keep the center of the crown dense.

Care Guide

Do

Plant in gritty or sandy soil that drains quickly after rain.
Shear back stems post-bloom to prevent untidy self-seeding.
Divide overgrown mats in early spring or autumn to maintain vigor.

Don't

Do not plant in heavy, waterlogged clay soils that retain moisture.
Do not apply rich organic fertilizers, which lead to weak, flopping stems.
Do not overwater established plantings.

Common Questions

Field Chickweed questions

What zones can Field Chickweed grow in?

Field Chickweed is hardy in USDA Zones 4–8. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.

Is Field Chickweed deer resistant?

Not reliably. Deer may browse Field Chickweed, especially tender spring growth — plan on repellents or fencing where pressure is high.

When does Field Chickweed bloom?

Field Chickweed typically blooms in spring through summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.

Does Field Chickweed need full sun?

Field Chickweed does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.

Is Field Chickweed drought tolerant?

Yes — once established (usually after the first full season), Field Chickweed handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
