How to Correctly Identify Hedge bedstraw (Galium album)

The genus Galium contains several similar species, so reliable identification for Hedge bedstraw (Galium Album) rests on a few features: the square stem, the whorled leaves, and the structure of the flower clusters.

Stem and growth habitat

Hedge bedstraw (also commonly known as White bedstraw) is a medium to tall plant, often scrambling over surrounding vegetation rather than standing upright. The stems are square in cross-section, smooth, and usually hairless, which separates the plant at a touch from grasses and from the clinging cleavers (Galium aparine), whose stems are covered in tiny hooked bristles that catch on clothing.

Whorled leaves

The leaves are the most distinctive vegetative feature. They are arranged in whorls of six to eight around each node, like the spokes of a wheel, rather than in opposite pairs. Each leaf is narrow, oblong to elliptical, pale green, single-veined, and tipped with a small point. This whorled arrangement is shared across the bedstraws and immediately rules out most other white-flowered plants of the same habitats.

Flowers

From June to August (this depends a lot on regional growing factors) the plant produces large numbers of small white flowers, each only two to three millimetres across and divided into four pointed lobes, carried in loose, branched clusters. The white flowers distinguish it from lady’s bedstraw (Galium verum), which has bright yellow flowers and finer, almost needle-like leaves. The closely related Galium mollugo is harder to separate: it tends to have slightly smaller flowers and flower-stalks that are longer than the width of the flower, whereas in Galium album the flowers are a little larger and the stalks shorter. The two are treated by some authorities as a single aggregate.

A reliable rule

Before naming a plant as hedge bedstraw, confirm three things together: a smooth, square, hairless stem; leaves in whorls of six to eight; and loose branched clusters of small, four-lobed white flowers. Yellow flowers indicate lady’s bedstraw. The stems usually are thin and tend to not hold up the plant well on their own. Another thing regarding the stems – when picking this plant, the stems will easilly bend with sharp angles (the stems are relatively fragile). As with any wild plant, never rely on a single characteristic, and never consume a plant you cannot name with certainty.
