Edible Uses

Edible Parts: Seed
Edible Uses:

One report suggests that it might be edible but gives no details[177]. It is quite probably referring to the seed (which is small and very fiddly too utilize) but might be referring to the base of the leaf stems, which is eaten in one other member of this genus.

Propagation

Seed - surface sow in the spring in a cold frame. Do not allow the compost to dry out. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Division in the spring. Very easy, larger divisions can be planted out direct into their permanent positions. We have found that it is better to pot up the smaller divisions and grow them on in light shade in a cold frame until they are well established before planting them out in late spring or early summer.

Rich (for Michael Frankis)   Tue May 8 2007

Found an error on this page: Range: Most of Europe, including Britain, to N. Africa, temperate Asia (delete North America, where only introduced, not native) Also the English name should be given as Smooth Meadow-grass: (not Kentucky Bluegrass, an invalid US renaming of the species only applicable to cultivated strains in the USA) Thanks, Michael Frankis
