Galium spurium aka False Cleavers

Galium spurium, or false cleavers, is an annual plant. It belongs to the Rubiaceae family. Plants for a Future gives its range as Europe, North Africa, and western Asia. Its wider distribution list also reaches eastern Asia, including China, Korea, and Japan. Its status in Britain is less clear. Plants for a Future questions whether it is native there. The RHS lists it as non-native to Britain and Ireland. It grows in arable fields in Essex and scattered British sites.

False cleavers reaches about 2.6 feet [0.8 metres] tall. As an annual, it completes its life cycle in one year. The supplied species account records flowers in July. Each flower has both male and female parts. Flies and beetles pollinate the flowers. The plant is also self-fertile. The evidence gives no species-level details about its leaves or stems. It also gives no flower colour or fruit description. The RHS describes these features for the genus, not this species.

Choose a partly shaded site with loose, moist soil. Soil rich in leaf matter suits the plant. It accepts sandy soil, loam, and clay. Its soil pH range runs from mildly acid to mildly alkaline. Although it tolerates dry ground, moisture remains its stated preference. Full sun can soon scorch the leaves. The plant also grows poorly in a hot climate. These limits matter when choosing a place in a cultivated bed. The supplied sources give no hardiness rating or winter temperature limit.

Plants for a Future recommends sowing seed where it will grow. Sow freshly ripe seed in late summer for its preferred method. Spring sowing in place is another option. However, spring-sown seed may take a long time to germinate. The source lists cultivated beds as a growing location. It also records the plant in farmed ground in Britain. These records describe where it grows, rather than a particular ornamental role.

The leaves can be eaten raw or cooked. Plants for a Future presents them as food for scarcity, not a choice crop. It gives edibility a low rating of one out of five. The roots provide a red dye. The source reports no known hazards. That statement does not establish safety for pets. The supplied evidence identifies no species-specific pests or diseases.
