Medicago monspeliaca: complete guide

Overview

Medicago monspeliaca, commonly known as hairy medick or Montpellier medick, is an annual to short-lived perennial herbaceous plant in the pea family. This plant is renowned for its vibrant yellow flowers and unique star-shaped seed pods packed with seeds. It grows naturally throughout the Mediterranean and beyond.

Appearance and bloom

The plant reaches 30-60 centimeters tall and forms a loose, sprawling growth habit. The leaves are trifoliate and distinctly veined. The bright yellow flowers appear from April to July in small compact clusters. After blooming, characteristic star-shaped seed capsules develop with papillate projections.

Ideal location

Medicago monspeliaca grows best in full sun with at least 6 hours of direct sunlight daily. The plant prefers open, ventilating positions. Partial shade is acceptable but flower production will decline. This plant is exceptionally tolerant of windy conditions.

Soil

Dry, well-draining soil is essential. The plant tolerates acidic to neutral soils, though lightly alkaline soil is favorable. Poor soils are not a problem - like most legumes, Medicago monspeliaca can fix atmospheric nitrogen. Avoid heavy clay soils.

Watering

Once established, Medicago monspeliaca tolerates significant drought. Water regularly during the first growing season. Thereafter the plant can rely on natural rainfall in temperate climates. In extreme drought, supplemental water can help boost flower production.

Pruning

Pruning is unnecessary, though you may remove spent flower clusters to stimulate reblooming. Self-seeded plants often perform better than pruned older material.

Maintenance calendar

April-May: Plant germinates, water regularly. May-July: Bloom period, minimal care. July-August: Seed setting, reduce water. August-October: Seed maturation, withhold water. October-March: Dormant, dead material can remain for overwintering.

Winter hardiness

Medicago monspeliaca is moderately hardy and tolerates temperature drops to approximately -8 degrees Celsius. In areas with harsh winters, the plant is typically grown as an annual with seed sown in spring. Plants from warm regions may overwinter.

Companion plants

Yellow flowering species pair perfectly with other Mediterranean plantings. Combine with purple sage, lavender, or rosemary. Silver-foliaged plants like perovskia create lovely contrast.
