Galium verum

Galium verum, also known as Yellow Bedstraw, is a beautiful fragrant plant whose intense yellow panicles have become rarer in European landscapes. Formerly used widely by herbalists, cheesemakers, and dyers, this botanical species is endangered in nature due to hybridisation with its cousin, white bedstraw (G. album), which is more prolific. Its generosity and beauty as a wild plant merit a closer look at this perennial. It grows in a spreading clump, and from June to September its modest foliage disappears under magnificent golden clusters. Perhaps it will find a safer haven in our gardens: ornamental, fragrant, undemanding, hardy, and capable of adapting to a wide range of moist to dry soils, true bedstraw will be satisfied with a full sun or partial shade.

Galium verum belongs to the Rubiaceae family and the genus Galium, which includes about 400 species of cosmopolitan annuals and perennials. It is native to Europe, western, northern, and eastern Asia, and northern Africa.

Yellow Bedstraw is an herbaceous perennial ground cover with trailing rhizomes. All the aboveground parts of the plant are fragrant and were once used dried as bedding material. It forms a clump of upright leafy stems that reach about 50 cm (20in) in height (sometimes up to 70 cm (28in)) when in flower, and spread over the ground over time to about 80 cm (32in). The stems, erect and robust, have a quadrangular section in the lower part, cylindrical towards the top. They bear very small, thread-like leaves, quite thick, with clearly rolled edges and of a bright green colour, arranged in whorls of 8. This means they are inserted at the same level on the stem. The flowering continues throughout the summer, in the form of large terminal cymes (or clusters) where countless small yellow and fragrant flowers, visited by pollinating insects, are tightly packed. Each flower measures about 3 mm (0in) in width. The corolla, in the shape of a wheel, is composed of 4 petals fused at the base. The fruit, glabrous and smooth, consists of 2 globular chambers, about 1.5 mm (0in) wide. The root secretes a red juice that was once used to dye wool.

Yellow Bedstraw is a drought-tolerant plant: its long, robust, and highly branched root sinks deep into the soil to draw in moisture. Its rhizome serves as a reserve organ to survive periods of scarcity. Finally, its thread-like and rolled leaves allow it to effectively reduce water loss through evapotranspiration.

Galium verum is a wild plant and as such it finds its place in a rural or wild setting. It can form beautiful associations with blue false indigos, grasses, toadflaxes, or perennial or shrubby sages. Pretty annual plants like love-in-a-mist, cosmos, or poppies will also be lovely companions for this unassuming plant. In a rock garden, it will blend well with catmints or Campanula rotundifolia. It is also a good plant for coastal gardens.
