Adjust frequency if rainfall is sufficient to maintain moisture levels.
LightBishop's Hat thrives in partial to full shade conditions. It should be planted in a location that receives filtered sunlight or light shade throughout the day.

While it can tolerate a range of temperatures, the plant is hardy in USDA zones 5 to 9, which means it can survive minimum winter temperatures down to -20°F. Ideally, it should not be exposed to extended periods of heat above 80°F for optimal growth.
PruningPrune Bishop's Hat to remove dead or damaged foliage, maintain shape, and promote denser growth. The best time for pruning is late winter or early spring, just before new growth starts. Cutting back the plant every few years encourages rejuvenation. Prune sparingly, as excessive pruning can reduce flowering.

Life cycleEpimedium × youngianum 'Merlin', commonly known as Bishop's Hat, begins its life cycle as a seed, which, once sown, germinates in moist, well-drained soil in a shaded area. Seedlings emerge and establish a robust root system, forming a clump that gradually expands through rhizomatous growth. In early spring, heart-shaped leaves unfold, often with a bronze tint, followed by the unique spur-shaped purple flowers that rise above the foliage on slender stems. After blooming in late spring to early summer, the plant enters a phase of vegetative growth where the foliage matures to a lush green and provides ground cover throughout the summer. As autumn approaches, the foliage may take on a reddish tinge. In winter, the plant becomes dormant, with some leaves remaining evergreen in milder climates, and the cycle begins anew with the return of spring growth.
PropogationPropogation time
Early spring
The most popular method of propagating Epimedium × youngianum 'Merlin', commonly known as Young's barrenwort or Bishop's Hat, is by division. This is typically done in late summer to early fall, after the flowering season has concluded or in early spring before new growth begins. It involves carefully lifting the plant from the ground and gently separating the clumps into smaller sections, ensuring that each new section has a portion of the root system and several growth points. These divisions are then replanted at the same depth they were originally growing at, spaced approximately 12 to 15 inches (30 to 38 cm) apart to allow sufficient room for growth. The divisions should be watered thoroughly after planting to help establish them in their new locations.
