About this plant
Big Blue Lilyturf is an evergreen herbaceous perennial groundcover with fine, grass-like foliage and violet-purple flower spikes in mid to late summer. Hardy zones 5-10, it thrives in part shade where foliage color is densest, though it tolerates full sun to full shade. Drought tolerant once established and adaptable to clay soils, it excels as a border edger, mass planting, or groundcover under trees.
Your 1 gallon container plant arrives nursery-grown and ready to plant into the garden or a larger container. Plant on arrival or within a few days, in average to well-drained soil. Water regularly through the first growing season to help establish roots. Space clumps 12-18 inches apart for faster coverage, or wider for individual specimens.

Questions before you buy
What does the 1 gallon size mean, and how much coverage will I get?
The 1 gallon container holds a young, nursery-grown clump 12-18 inches in width. For full coverage in a given area, space clumps 12-18 inches apart; if planted further apart, plants will gradually spread via short rhizomes and fill in over a few years.
When should I plant after it arrives?
Plant on arrival or within a few days. Big Blue Lilyturf establishes best when planted in spring or early fall, though it can be planted during the growing season if watered regularly. Avoid planting in peak summer heat or late fall in zones 5-6.
How large does Big Blue Lilyturf get?
Mature foliage reaches 12-18 inches tall and spreads 12-18 inches wide per clump. Flower spikes rise slightly above the foliage to about 18-24 inches. Clumps spread slowly via short rhizomes, advancing a few inches per year, reaching full mature size in about 2-3 years.
Does it need full sun?
Big Blue Lilyturf is highly adaptable and tolerates full sun to full shade. Best foliage color and density develop in part shade, making it ideal for under trees and shade gardens. It performs well in all sun conditions, so site it where it fits your garden design.
What are the hardiness zones, and will it survive my winter?
Hardy zones 5-10. In zones 7-10, foliage remains evergreen year-round. In zones 5-6, foliage may brown or die back in harsh winters, though roots survive and regrow in spring. In all zones, it is winter-hardy and will return reliably.
What care does it need in its first year?
Water regularly through the first growing season to help establish an extensive root system, roughly one growing season. Once established, it is drought tolerant. Avoid fertilizing newly planted lilyturf; average soil is sufficient. Mulch lightly around the plant to retain moisture and suppress weeds during establishment.
