Cool Season Grasses: These grasses do the majority of their growing in early spring and continue until temperatures start to cool in the fall. During the warmer summer months, they stop growing and some will even go dormant. Cool season grasses flower in the spring or early summer. Most cool season grasses grow best in a consistently moist soil.

Bottlebrush Grass Growing and Maintenance Tips

Best grown in a moist, fertile soil, however, it is quite tolerant of any soil type from heavy clay to dry and rocky. Grows in full sun or partial shade, however, it will struggle in the hot sun. This is a good choice for naturalizing dry, shaded areas. Hystrix patula will freely self-seed in optimum growing conditions and seed heads can be pruned off before they disperse. Grass should be pruned down to almost ground level in early spring.
