Juncus patens 'Carman's Gray' – California Gray Rush

Add cool gray texture and upright structure with 'Carman's Gray' California Gray Rush.

Juncus patens 'Carman's Gray' is a grass-like perennial rush, not a true ornamental grass. Its slender gray-green to blue-gray cylindrical stems form compact upright clumps, creating a clean architectural contrast beside broad-leaved perennials and softly arching grasses. Small brown flower clusters appear near the stem tips in spring and summer. Repeat it along a rain garden, tuck it beside a water feature, or use it as a vertical accent in a patio container. This selection tolerates wet soil and periods of dryness once established, although regular moisture helps keep the clumps looking full.
