Dried leaves can be toxic though the fresh leaves are quite safe[15]. This is due to the presence of coumarin, the substance that gives some dried plants the smell of new mown hay. Taken internally it can prevent the blood from clotting[9].

The dried leaves contain a substance called coumarin, this is an anti-clotting agent and has been used as a basis of the rat killer 'warfarin'[9]. The plant is a good green manure crop[7][18][4]. It can be sown in the autumn and overwintered or sown from spring to mid summer. It can be cut several times for compost material before being finally incorporated into the soil[18]. Fast growing, it produces a high bulk of organic material and also fixes a large quantity of atmospheric nitrogen[18]. It can also be grown under soft and top fruit, when it will expel mice[17].

Propagation

This section contains historical Plants For A Future notes marked noncommercial.

Seed - sow spring to mid-summer in situ[18]. Pre-soaking the seed for 12 hours in warm water will speed up the germination process, particularly in dry weather[K]. Germination will usually take place within 2 weeks.

Cultivation

This section contains historical Plants For A Future notes marked noncommercial.

A fast growing plant[18], it dislikes shade. A good bee plant[12][13]. The dried plant has a sweet smell of newly mown hay[11]. 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[8].
