Cultivation details

Succeeds in ordinary garden soil[1]. Prefers a well-drained loamy soil in full sun[200]. Cultivated in the Mediterranean for its leaves which are used as a flavouring[46, 61, 177]. 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[200]. When removing plant remains at the end of the growing season, it is best to only remove the aerial parts of the plant, leaving the roots in the ground to decay and release their nitrogen.

I grew up eating this stuff - the seeds of which came from a Bulgarian immigrant. We had three shakers: Salt, Pepper, & this magic herb (mixed with some other ingredients) & used it on various meats & vegitables. I have grown my own for decades.
