Growing and Maintenance Tips:

Molinia is slow to mature and could take 3-5 years to reach full size. Grows best in a moist, well-drained, acidic soil, in full sun to partial shade. You can trim back the dead foliage in the fall for a tidier appearance, or leave it until spring to improve winter interest and provide root protection.

Additional Notes about Moorhexe Purple Moor Grass:

Cool Season Grasses: These grasses do the majority of their growing in early spring and start again when 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.
