Cerastium arvense: complete guide

Overview

Cerastium arvense, commonly known as field chickweed or mouse-ear chickweed, is a low, herbaceous wildflower from the Caryophyllaceae family. Growing only 15-30 cm tall, this plant forms broad, compact mats with very fine, gray-green foliage. Flowers are pure white and appear in massive numbers in late spring. This is a plant for devotees of subtle, low growth and natural texture.

Appearance and Bloom Cycle

Field chickweed features very fine, hairy, gray-green leaves lying closely together. Stems are low and sprawling, forming rectangular mats that hold together without spreading excessively. Flowers are the highlight: pure white, approximately 1-1.5 cm across, appearing in countless numbers.

Blooming peaks from April through June. After flowering, small seed heads form that remain attractive deep into summer. Foliage stays green year-round, making Cerastium arvense an important texture element even in winter.

Ideal Location

Field chickweed thrives in full sun. This is non-negotiable; in shade the plant grows poorly and barely flowers. Provide at least 6-8 hours of direct daily sunlight.

Place field chickweed between stones, in dry borders, along pathways, or as groundcover between low-growing flowers. The plant pairs well with other drought-lovers like hens-and-chicks and sedums.

Soil Requirements

This is a plant for poor, lean soil. Cerastium arvense grows well in sandy, stony, or grit-rich soils that drain extremely freely. Heavy, moist clay soils are unsuitable.

A neutral to slightly alkaline pH (6.5-7.5) is ideal. Fertilizing is unnecessary and can be harmful; it stimulates excessive foliage at the expense of flowering.

Watering

Once established, field chickweed is very drought-tolerant. The plant accepts natural rainfall and needs no supplemental water except in the driest summers. Excess water is more harmful than drought.

In very wet winters on poor soils, the plant may perish. Always ensure excellent drainage.

Pruning and Maintenance

Field chickweed requires minimal maintenance. After blooming, you can lightly prune to maintain compact form, though this isn't always necessary. In spring, remove any winter die-back.

The plant self-seeds; manage this if unwanted.

Maintenance Calendar

Spring (March-April): Light pruning, remove winter damage Summer (May-August): Allow flowering, leave seed heads attractive Autumn (September-October): Minimal care, moisture management Winter (November-February): No maintenance; foliage remains ornamental

Winter Hardiness

Cerastium arvense is very hardy to USDA zone 2 (-45°C). This plant survives all Dutch, Belgian, and French winters without protection. Foliage remains green year-round and retains ornamental value.

Companion Plants

Field chickweed pairs well with:

• Hens-and-chicks (Sempervivum)
• Sedum (Sedum)
• Cranesbill (Geranium)
• Lavender (Lavandula)
• Thrift (Armeria)
• Pasque flower (Pulsatilla vulgaris)

The white flowers enhance other colors beautifully.
