Cultural hint & synonymy note: Recently taxonomists have lumped Epimedium brachyrrhizum into leptorrhizum, even when acknowledging the fact brachyrrhizum is a "clumper" with short rhizomes, whereas leptorrhizum is a fast spreading "ground cover" with long narrow annually expanding rhizomes. The former brachyrrhizum slowly builds into a domed clump, safe to grow amongst other well-behaved perennials and shade plants, whereas leptorrhizum grows much lower but spreading far and wide into a groundcover, and should only be planted where plenty of room is afforded. The distinct plant habits and growing considerations will become blurred over time when both plants are considered but one entity. I hope that helps. All the photos by me (Antman01) show the clumping Epimedium brachyrrhizum plant.
