Fenugreek, Greek Hay, and Fresh Menthi: Cultivation & Garden Use
Trigonella is a genus of half hardy annual herbs that reach from 30 to 60 cm (1 to 2 feet) in height. They have clover shaped foliage, and bloom from the middle of summer through to autumn. They carry small pea like flowers.
If growing for culinary use, then seed pods should be cut off the plant once they have ripened. Allow the Trigonella seed pods to dry in the sun, then remove the seeds and store in a dry and airtight container.

How to Grow Fenugreek (Trigonella)
