Warm Season Grasses: These grasses are much slower starting in the spring. They do not push new growth until temperatures warm in early to midsummer. They flower later in the summer or fall with most blooms remaining into the winter. Most warm season grasses tolerate heat, humidity and drought; some even thrive in these conditions.
