I use this is as a border plant--it is the perfect size. The pretty little bluish-purple flowers open in the morning and close up later in the day. It's just a charming and easy long-blooming perennial. The blue-green grass clump itself is attractive as well. I divide the clumps every third year or so.

This grassy perennial is a bloom machine. It blooms for months for me with no special care at all. I highly recommend it. No deadheading and no fertilizer except a top dressing of compost. Love it.

This is a beautiful little evergreen grass which I planted in 2006 and 2007. It does well in full sun, but does not like too much water. I planted many to border our sidewalk and most of them loved their new home initially. Now it is spring of 2010 and most of them have died out. It appears from too much water or over crowding. It seems they like to be on the dryer side or have a lot of room. I'm not sure what the problem was with most of them. Too bad because it is a beautiful little grass.

This lovely plant grows all over North Texas meadows. I dug one small plant up and planted it close to my pond were it receives morning sun, but I know it can take full sun. It is it's second year now and had quadrupled in size. I will try to devide the plant in fall and see what happens, but I think it propagates by seeds also. The flowerheads close in the evening and open up again in the morning. The
deep blue flowers with the yellow "eye" looks very nice against the greyish-blue leaves. I will make sure that I have several plants of it.

I first purchased this lovely plant at a native plant sale. I used it to edge part of my driveway. It is one tough cookie! It has done beautifully right next to the macadam, with minimal care. Blooms for quite a long time and is a nice complement to my asclepia tuberosas.
