Cruciata pedemontana, known as Piedmont bedstraw or croisette du Piedmont, is an elegant European groundcover in the Rubiaceae family. Growing from North Africa through Central Asia, this species is renowned for its delightful yellow flowers.

Overview

Piedmont bedstraw is a low, creeping plant reaching 30-60 centimeters long. With its yellow flowers and elegant leaf form, this plant provides attractiveness with minimal maintenance. The plant spreads via runners and establishes easily in suitable conditions.

Appearance & Bloom

The plant features small, linear leaves in whorls along the stem, from which the name 'cruciata' derives. From June through July, star-like yellow flowers appear in leaf axils. These flowers attract bees and other insects. After flowering, small, rough-haired fruits develop.

Ideal Location

Place in full sun to partial shade. In warm climates, partial shade is preferred. The plant grows well on slopes, in wild corners, and under trees. This is not a plant for boggy sites.

Soil

The plant grows in virtually all soils, from acidic to neutral. Dry, gravelly soil is well tolerated. In containers: universal potting soil with sand. The plant is not critical and values poor soils.

Watering

Minimal water once established. Regular water during the first growing year. Dryness is well tolerated. Excessive moisture causes rot.

Pruning

Maintenance Calendar

Winter Hardiness

Winter hardy to USDA zone 5a (-15 degrees Celsius). No winter protection needed in temperate regions. This plant typically retains its leaves.
