WaterFor Barrenwort, the watering should be done deeply and infrequently to encourage root development. This perennial should be watered about once a week with approximately 1 gallon of water per plant, depending on the local weather conditions; more often during dry spells and less frequently when it's cooler or rainy. In early spring, water can be reduced until new growth appears and then increased as temperatures rise, ensuring the soil remains moist but well-drained. In the fall, taper off watering as the plant goes dormant.
LightBarrenwort thrives in light conditions ranging from full shade to partial sun. The best spot for Barrenwort would be a location where it can receive filtered sunlight or morning sun followed by afternoon shade. Avoid placing it in an area where it would be exposed to harsh, direct afternoon sunlight, which can scorch the leaves.
TemperatureBarrenwort prefers moderate temperatures and can tolerate a range between 50 to 75 degrees Fahrenheit. It can survive minimal winter temperatures down to around 10 degrees Fahrenheit but should be protected from extreme cold. The ideal growing condition for Barrenwort is a spring or fall-like temperature, where it isn't too hot or too cold, typically around 60 to 70 degrees Fahrenheit.
PruningPrune Barrenwort annually in late winter or early spring, before new growth starts. Pruning involves removing dead and damaged leaves to maintain plant health and invigorate new growth. Also, trimming back any old foliage will improve the overall appearance and make room for new leaves. The best time for pruning is when the plants are still dormant.
CleaningAs needed
SoilBishop's Hat prefers well-drained soil rich in organic matter with a slightly acidic to neutral pH of 5.5 to 7. The best soil mix can be prepared by combining garden soil, compost, peat, and perlite to ensure good drainage and fertility.
RepottingBishop's Hat does not require frequent repotting and can often be left undisturbed for several years. It should generally be repotted every 3 to 4 years to refresh the soil and divide the rhizomes if necessary.
Humidity & MistingBishop's Hat thrives in average to high humidity levels. While it tolerates a range of humidity conditions, maintaining humidity levels around 50% is ideal for this plant.

Life cycleEpimedium grandiflorum 'Rubinkrone', commonly known as the Red Crowned Epimedium, begins its life cycle as a dormant rhizome which sprouts in early spring. The foliage emerges with a red tint, followed by the development of characteristic heart-shaped leaves. During the spring, it produces small, delicate flowers with a striking combination of red sepals and white petals, which hover above the leaves on wiry stems. After the flowering period, the plant continues to grow and fill out, providing dense ground cover throughout the summer months. In the autumn, the foliage may take on a bronze hue before dying back. The rhizome overwinters and survives frost and cold, ready to restart the cycle the following spring.
PropogationPropogation time
Spring to early summer
The most popular method of propagating Epimedium grandiflorum 'Rubinkrone', commonly known as Barrenwort, is by division. This is best done in the fall or early spring before new growth begins. Gardeners should carefully dig up the clump, keeping as many roots intact as possible. Once the clump is lifted from the soil, it can be divided by gently teasing apart the roots or using a sharp knife to cut through them. Each section should have at least one growth point or bud. The divisions can then be replanted at the same depth they were previously, spacing them about 12 to 18 inches (approximately 30 to 45 centimeters) apart to allow enough room for growth. This process rejuvenates the plants, ensuring healthier and more vigorous growth.
