Tall, thin foliage grows upright and has a fountain-like appearance, allowing the Whirlwind Purple Moor Grass to make a big statement in a landscape. Light brown flowers bloom during the summer and have a soft, feathery texture for added dimension and subtle color. The flowers bloom on tall spikes that stand just above the foliage, and by fall, the flowers turn to seed pods for yet another season of visual interest.

Whirlwind Purple Moor Grass has a strong, upright growth habit, making it a good choice for windswept areas. Plant in beds or borders for texture or use as an accent near steps leading to a porch or near a mailbox. This tall plant will reach about 4 feet in height, so it can easily command a large area. This ornamental grass is clump-forming and grows as a perennial in USDA zone 4.

Whirlwind Purple Moor Grass Care

Plant Whirlwind Purple Moor Grass in an area that receives at least 5 hours of sunlight. Water this grass when the top few inches of soil dry out. The soil should be rich, moist, and neutral to acidic. Apply a layer of organic mulch around the base of the plant or feed using a balanced fertilizer each spring.

This is a herbaceous perennial, so all growth will die back after the frost. Remove damaged growth or trim the greenery back to a few inches in the fall.

Whirlwind Purple Moor Grass Spacing

Whirlwind Purple Moor Grass has an upright form and will reach 4 feet tall and wide. Plants can be spaced 4 feet apart to create a thick, dense look.
