Species & Cultivars
Big Blue Lilyturf (Liriope muscari): This lilyturf grows in a clump form, making it well-suited for edging. The leaves are a little wider (3/8 to ½-inch wide) and the flowers somewhat bigger than those of creeping lilyturf.
- ‘Majestic’ is a strong grower that grows to 12 to 15 inches tall. It has large, showy, deep lilac flowers and ½-inch wide dark foliage.
- ‘Monroe’s White’ has bright white flowers in large clusters. Matures at 12 to 15 inches tall. This variety does best in shade, and has slightly slower growth.
- ‘Christmas Tree’ has unusual light lavender flower spikes in the form of a Christmas tree. It grows slowly to 12 to 15 inches tall, and prefers shade.
- ‘John Burch’ has a thin border of creamy yellow edging each leaf blade. It will have less variegation if grown in shade. The flowers are lavender and it grows to 12 to 15 inches tall.
- ‘Evergreen Giant’ has stiff-textured leaf blades and white flower spikes. Mature height is 18 to 24 inches tall.
- ‘Densifolia’ is very similar to ‘Evergreen Giant’, grows to 18 to 24 inches tall, and has lavender flowers spikes.
- ‘Gold Band’ is an excellent specimen plant. It has wide leaf blades with a gold edge and lavender flower spikes. Mature height is 12 to 18 inches.
- ‘Samantha’ is a green leafed cultivar with pink flower spikes. Mature height is 12 to 15 inches tall.
- ‘Big Blue’ matures at 12 to 15 inches tall and has less of a tendency to spread by stolons. It has lavender flower spikes.

- ‘Silvery Sunproof’ has leaves striped white and yellow. It withstands sun better than most variegated forms 12 to 15 inches tall, with purple flowers.
- ‘Webster Wideleaf’ has lavender flower spikes on 12 to 15 inch tall plants. Widest leaf of any cultivar.
Creeping Lilyturf (Liriope spicata): This lilyturf grows 10 to 15 inches tall and spreads indefinitely.
The leaves are more narrow (1/4-inch wide) than on L. muscari. This habit makes it ideal for a lawn replacement or erosion controlling groundcover. It can be invasive in the wrong location. The flowers are smaller and lighter in color.
- ‘Silver Dragon’ has slender, highly variegated green and white leaves and lavender flowers. It reaches about 12 to 16 inches tall. ‘Silver Dragon’ is great for lighting up a dark area. It does not grow as densely as most lilyturf.
- ‘Franklin Mint’ has pale lavender flower spikes above green leave that grow to 12 to 15 inches tall. The leaves are a little wider than those of ‘Silver Dragon’.
Mondo grass (Ophiopogon species) is similar in use and appearance to lilyturf. You can find information on mondo grass in HGIC 1110, Mondo Grass.
