WaterBishop's hat should be watered regularly to keep the soil consistently moist, especially during its growing season in spring and early summer. You would typically water this plant about once a week, but always check the top inch of soil for dryness before watering. When watering, apply water slowly and deeply until it begins to drain out of the bottom of the container, which may be approximately a quart of water for small pots or up to 1-2 gallons for larger outdoor plantings. During the winter months, reduce watering frequency as the plant enters dormancy.
LightBishop's hat thrives in partial shade to full shade conditions. The ideal spot for this plant would be an area that receives dappled sunlight or light shade throughout the day. Avoid placing it in direct sunlight, as this can scorch the leaves and diminish the plant's health.
TemperatureBishop's hat prefers growing in cooler temperatures and can tolerate a range of conditions. The ideal temperature range for this plant is between 50°F and 75°F. Bishop's hat can survive minimum temperatures down to 20°F, but it's important to protect it from extreme cold. Likewise, it can endure higher temperatures up to about 80°F, as long as it is not in direct sunlight.
PruningPrune Bishop's hat to remove any damaged or dead foliage, which helps to encourage new growth and maintain the plant's appearance. Light pruning can be done in early spring before new growth begins. Removal of old leaves after winter, before the new flowers and foliage emerge, is often recommended to allow for a fresh flush of growth.
CleaningAs needed
SoilBishop's Hat requires well-drained, loamy soil enriched with organic matter. The ideal pH range is slightly acidic to neutral, between 5.5 and 7. A mix of garden soil, compost, and perlite or sand can provide good drainage and fertility.
RepottingBishop's Hat doesn't need frequent repotting; do it every 3-4 years or when the plant outgrows its container. It's best to repot in the spring before new growth starts.
Humidity & MistingBishop's Hat thrives in moderate to high humidity levels, ideally between 40-60%. It can tolerate lower humidity but providing a humid environment is beneficial.
Suitable locationsIndoor
Place Bishop's Hat in a spot with bright, indirect light and ensure high humidity.

Life cycleEpimedium epsteinii, commonly known as barrenwort, begins its life cycle as a seed, which after stratification, germinates in spring when the soil warms. The seedling develops a rosette of leaves and a small root system, eventually becoming a juvenile plant. As it matures, barrenwort forms a clumping perennial with heart-shaped leaves and gains the ability to undergo vegetative reproduction through rhizome division, which helps to expand its growth. In the spring, the plant produces flower stalks with delicate blooms, usually in shades of yellow, red, or purple, depending on the cultivar. Following pollination, seeds are produced and dispersed, allowing barrenwort to colonize new areas. It is a resilient plant that enters dormancy in winter, with foliage dying back, only to emerge again from its roots with new growth the following spring.
PropogationPropogation time
Spring to summer
Propogation: The most popular method of propagation for Epimedium epsteinii, commonly known as Barrenwort, is division. This is typically done in the spring or early fall when the plant is not in active bloom. To propagate by division, carefully dig up an established clump of Barrenwort and gently separate the rhizomes, making sure that each division has at least one growth point or bud. These divisions should then be replanted immediately at the same soil depth they were previously growing, spaced about 12 inches (roughly 30 centimeters) apart to allow ample room for growth. Water the new divisions thoroughly after planting to help establish them. This method of vegetative propagation not only helps to increase the number of plants but also rejuvenates older clumps that may have become woody or less vigorous over time.
