Searching Category for GRASSES
One of the most important things to understand about ornamental grasses is the distinction between cool and warm weather grasses.

Cool season grasses begin growth, logically, in the cool of spring or early summer and are, generally speaking smaller, mounding species.

Warm season grasses do not emerge until summer, when it is not just warm, but hot. Most warm season grasses are taller, upright species and do not really come into their own until the autumn.

Understanding the differences is the only way to know how to use them in the landscape. For example, if you plant a warm-season grass in a prominent spot in your garden, make sure you are willing to live with what appears to be a dead-looking clump until mid summer.

A genus of 100 species of widely distributed grasses. Many are elegant and subtle plants, extremely ornamental in the fall, turning a rich orange-wheat colour. For full sun in well-drained soil.

Foliage resembles palm fronds which gives this plant a very tropical appearance. Distinctive brown seeds dangle in between the leaves from summer onwards. For sun or shade. Prefers moist soil and will grow in shallow water 3-4" deep, when young, deeper as it matures. Will flop in too much shade.
