Artistic considerations aside, there are also excellent practical reasons to consider adding ornamental grasses to your borders.

· Warm-season grasses wait until the weather starts heating up to put on most of their growth, so they're ideal for filling spaces left when spring bulbs and early-flowering perennials go dormant in early- to midsummer.

· Sturdy grasses can help minimize staking chores because they'll mingle with and support weaker-stemmed partners in a way that's as alluring as it is labor-saving.

· Low to medium-height grasses are perfect companions for covering the "bare ankles" of taller-growing perennials that tend to lose their lower leaves as the season progresses -including bee balm (Monarda spp.) and border phlox (Phlox paniculata), to name just two.

Yes grasses can look very effective just like the picture shows. my only worry is whether they soon get out of hand and spread too far too fast.

I just think you have to keep control of grasses like any thing that grows in the garden

Admin is it a lot of work to keep the grasses under control?
