Appearance & Bloom Cycle

Smooth Bedstraw is a low-growing plant reaching 20-40 cm in height. The plant spreads underground via rhizomes, forming dense mats. Leaves are arranged opposite in whorled patterns, creating the characteristic cross-shaped arrangement. Foliage is smooth and dark green.

Flowers appear in yellow-green, very small but remarkably numerous, assembled in compact flowering clusters. They bloom April through May, marking the plant as a spring harbinger. Flowers emit pleasant fragrance, attracting pollinators.

Ideal Location

Smooth Bedstraw thrives in dappled to full shade. The plant tolerates full sun but performs better in moderate light conditions. This makes it ideal for woodland edges, under shrubs, and in dark garden corners.

Soil Requirements

This plant demands moist, humus-rich soils. Acidic to neutral soil is preferred, though the plant accepts slightly alkaline conditions. The plant grows vigorously in woodland soil enriched with organic matter.

Watering

Smooth Bedstraw requires regular water during the growing season (April-October). Especially in dry periods, supplemental irrigation is necessary. In rainy seasons, natural rainfall suffices. Established plants often thrive independently.

Pruning & Maintenance

The plant requires minimal pruning. You may cut back in September-October to encourage more compact growth. Dead foliage can be removed in spring.
