Sesleria caerulea - Blue Moor Grass

A wide range of conditions will suit Blue Moor grass and like S. heufleriana it is best to supply ample moisture in hot dry areas.

Very good for mass planting and as a large scale groundcover. Does not take the amount of traffic that a lawn grasses can stand, but with very little traffic it makes a good lawn substitute. Also good for edging and between stepping stones.

Looks nice with early spring bulbs. Blue Moor grass also makes a great groundcover or can be used as a filler plant in borders.

The Latin word caerulea means sky blue or true blue.
