Epimedium × perralchicum 'Frohnleiten' is a compact, clump-forming barrenwort that shines in shade with airy clusters of bright yellow spring flowers held just above a low mound of foliage. You will appreciate its heart-shaped leaves that often keep their presence through winter and show bronzy tones during the cool seasons. Mature size is typically 6-12 inches tall, with a slowly expanding footprint as the rhizomes knit into a tidy groundcover.
Plant it in partial shade to full shade in well-drained soil enriched with organic matter, such as woodland beds, under trees, along shaded paths, and at the front of borders. Keep it evenly moist while it establishes, then it can handle short dry spells and drier shade better than many perennials. Mulch with leaf mold or shredded bark to protect the roots and conserve moisture, but keep mulch off the crown.
For best spring display, trim away any winter-worn foliage in late winter or very early spring before new growth pushes. Space plants about 12 inches apart for a quicker fill, or farther apart for a slower, patch-forming look. This cultivar is valued for low maintenance, reliable seasonal interest, and strong performance where grass struggles.
