The luminous qualities of decorative grass plants add a silvery elegance to our late season gardens. Sunshine lights up their plumes like quicksilver. The gentlest breeze sets them in to a graceful, musical dance. They define our landscapes with linear, architectural strokes that can be dainty or bold. While most decorative grass plants will be happiest growing in full sun, there are a number of gorgeous shade loving varieties that will brighten up a shady garden. With an impressive variety of color, size and texture you'll be sure to find just the right spot for them in your garden. Whether reaching for the sky with a towering Andropogon (Big Bluestem) or a planting of Nassella (Mexican Feather Grass) to gracefully spill on to a pathway, we really can't do without these stalwarts of the late summer gardens.
In general, the blade like foliage starts to emerge in late Spring-early Summer. Depending on the variety, grass plants provide a defined linear graphic to the garden as they emerge, followed by an abundance of graceful arching foliage later into the Summer . Again, depending on the variety, their silvery plumes arise in late Summer into the Fall finishing off a soft tawny- buff color in late Fall into Winter.
