Edible Uses

Edible Parts: Seed
Edible Uses:

Seed - raw or cooked[105, 161, 257]. Although quite small, the seed was a staple food for some native North American Indian tribes[257]. Rich in oil, it can be roasted then ground into a powder and eaten dry, mixed with water, or combined with cereal flours[105, 161, 257]. The seed was also used as piñole[257].

Cultivation details

We have very little information on this species and do not know how well it will grow in Britain, though it should succeed as a spring-sown annual. Some botanists say that it is no more than a form of M. elegans, a species that does succeed in this country. The following notes are based on the needs of that species. Succeeds in any good garden soil[1]. Prefers a deep open sharply drained soil in a sunny position[200]. Another report says that it is best in a shady position[1]. The flowers open in the morning or evening, closing when exposed to bright sunlight[200].
