Lady's bedstraw

Sun

Full sun is best; tolerates light shade but may flower less and flop.

Water

Low to moderate; water regularly while establishing, then mainly during prolonged drought.

Soil

Well-drained, lean to moderately fertile soil; particularly suited to chalky, limestone and sandy soils. Avoid waterlogged ground.

Height

1-3 ft (0.3-0.9 m)

Spread

1-2 ft (0.3-0.6 m) initially; creeping roots can spread much farther over time.

Flowers

Summer to early autumn; dense clusters of tiny golden-yellow flowers.

Foliage

Narrow, dark green leaves arranged in whorls around slender, sometimes sprawling stems; leaf edges are rolled under.

Growth

Moderate to fast once established.

In the garden

Spreads vigorously: plan to contain it.

Growth rate

Fast

• Water new plants through their first growing season, allowing the surface soil to dry between waterings.
• Avoid routine feeding; rich soil encourages soft, floppy growth.
• Keep winter drainage good and avoid thick, moisture-holding mulch over the crown.
• Lift spreading edges in spring to keep colonies within bounds.
• Divide crowded clumps in spring and replant only the portions you need.

Pruning. Cut spent flower stems back after flowering if you want to limit self-seeding. Cut remaining dead growth close to the ground in late winter or early spring before new shoots lengthen.

Early spring

Cut back dead stems and remove unwanted shoots around the colony.

Spring

Plant or divide clumps into well-drained soil; water thoroughly.

Late spring

Check that neighbouring plants have room and lift any spreading edges that are crowding them.

Summer

Water young plants during dry spells; established colonies usually need little extra water.

Late summer

Remove fading flower stems before seed ripens where seedlings would be unwelcome.

Autumn

In meadow plantings, cut after flowering and seed set, then remove the cut material to keep fertility low.

• Weave through a sunny meadow with fine grasses and oxeye daisies for a soft yellow summer layer.
• Plant in informal cottage borders with field scabious and hardy geraniums, allowing room for spreading.
• Use in a sunny gravel garden to contrast its fine foliage with upright flower spikes.
• Grow in a wildlife border where its small, accessible flowers can support visiting insects.

Garden styles it suits: Cottage garden, Wildflower, Wildlife garden, Pollinator garden, Dry gravel garden and Sensory garden.

Plant it with: Field scabious, Oxeye daisy, Common knapweed, Sheep's fescue, Meadow sage and Bloody cranesbill.

Wildlife: Flowers provide nectar and pollen for bees, flies and other insects. The foliage is food for several moth caterpillars, including bedstraw-feeding hawk-moths where they occur.

• Unwanted spread: creeping roots and seedlings can crowd nearby plants; lift the edges regularly and remove flowers before seed ripens.
• Flopping stems: shade or rich soil encourages weak growth; move to a sunnier position and stop feeding.
• Winter losses in wet soil: improve drainage or move plants to a raised, free-draining site.
• Powdery mildew: dry roots and crowded growth can encourage a white coating on leaves; improve airflow and water the soil during prolonged drought.

Not known to be toxic to people, cats, dogs or horses. Species-specific safety information for pets is limited; do not treat the leaves, stems, flowers or roots as food or allow animals to eat large quantities.

Where it spreads. Spreads by creeping roots and seed. It is introduced and reported as invasive in parts of the northeastern and midwestern United States, where it can invade grassland. Check local guidance before planting outside its native Eurasian range, and keep it away from natural grasslands.

• Hedge bedstraw (Galium mollugo)

  Has white rather than yellow flowers and generally broader leaves.

• Cleavers (Galium aparine)

  An annual with hooked, clinging hairs, broader leaves and tiny whitish flowers rather than dense yellow flower clusters.

• Crosswort (Cruciata laevipes)

  Has broader leaves in whorls of four and small yellow flower clusters at the leaf joints, rather than large clusters at the stem tips.

The name bedstraw refers to the historical use of its dried, sweet-smelling stems and leaves as mattress stuffing.

Propagation. Divide rooted clumps in spring or early autumn. Sow seed outdoors in autumn, or in spring; germination can be uneven, and a period of cold, moist conditions may help.
