We seem to have forgotten about grasses. I love all the Pennisetums, their big obvious flowers create interest throughout the year, even in the winter. I`v tried the blue Festuca glauca but it usually succumbed to the "weather". There are many varieties to-day but I suspect they are all as good or bad as the original. Miscanthus sinensis" Gracillimus" is a great plant for the back of the border; it will spread given the chance. Stipa tenuifolia turns bright yellow and flows like water.
Two lawn grasses are Zoysia which has to be transplanted in the autumn. This then creates a new problem dealing with the annual weeds which pop up before the grass covers over. It grows in lumpy waves and would be very difficult to cut. Needs some water. The other grass is Cynodon dactylon. This is usually grown from rooted cuttings which you can prepare yourself simply by selecting plants in the wild and then growing them on in pots until ready for planting. C dactylon responds to water and fertiliser.
Some grasses can be invasive so please check before planting ie Cortaderia
