Water Saving Tip:

Replace turf with groundcovers, trees, and shrubs. If you have areas where no one uses the grass, patches that do not grow well, or a turf area too small to water without runoff, consider replacing the turf with water-efficient landscaping.

  • Description

  • Notes

Intense blue coloration makes Boulder Blue a standout in the landscape. Grows 15 inches tall and 12 inches wide. Plumes are green to creamy white, turning wheat colored in the fall. Very upright habit. Taller than F. 'Sea Urchin.' Use in the perennial border or as a groundcover, though it isn't well suited for areas with foot traffic. It does look fabulous surrounding pavers for a walk or patio. Evergreen, or very nearly so.
Grows in full to part sun and well drained soil. Soggy or wet soils will cause it to rot out. No need to deadhead; birds love the seeds and the plume tend to breakup and fall apart on their own. Blends beautifully with thyme, sunrose, and pussytoes. Great in parkstrips.
