Safety & Hazards

The seed is said to contain trypsin inhibitors[1]. These can interfere with certain enzymes that help in the digestion of proteins, but are normally destroyed if the seed is sprouted first.

Cultivation Details

HabitAnnual/Perennial
GrowthMedium

Medicago lupulina is a plant of the temperate zone, where it is found at elevations up to 3,600 metres. It grows best in areas where annual daytime temperatures are within the range 14 - 25°c, but can tolerate 3 - 30°c[2]. The young growth in spring can be severely damaged at temperatures below -2°c[2]. It prefers a mean annual rainfall in the range 600 - 1,000mm, but tolerates 310 - 1,700mm[2]. Grows best in a sunny position, tolerating light shade[2]. Succeeds in a wide range of soils[2], though it dislikes acid soils[3]. (This conflicts with the notes on its habitat above.) Prefers a pH in the range 6 - 7, tolerating 4.5 - 8.2[2]. A good food plant for many caterpillars[4]. A very variable species[5]. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[6].

Propagation

Pre-soak the seed for 12 hours in warm water and then sow in spring in situ[6]. The seed can also be sown in situ in autumn. Green manure crops can be sown in situ from early spring until early autumn[3]. (the later sowings are for an over-wintering crop) Cite as: Temperate Plants Database, Ken Fern. temperate.theferns.info. 2026-02-21. <temperate.theferns.info/plant/Medicago+lupulina>
