Pollination Info for Red Barrenwort (Epimedium x rubrum)

Red Barrenwort is a self-fertile plant but requires pollinators for best results. The plant is pollinated by bees, butterflies, and other insects. The flowers of Epimedium x rubrum produce small amounts of nectar and are rich in pollen, attracting different insect species. The larger insects such as bees and butterflies are more efficient pollinators as they can carry higher amounts of pollen and have longer tongues, enabling them to reach the nectar deep inside the flower.

The Red Barrenwort plant produces small flowers that are not very showy, and as a result, the plant may not attract many pollinators. Therefore, it is essential to grow Red Barrenwort alongside other nectar-rich and showy flowers to attract a diverse community of pollinators.

In addition to insect pollination, Red Barrenwort can also self-pollinate. The plant produces flowers with both male and female reproductive parts. The plant can produce seeds by itself, but cross-pollination ensures genetic diversity, leading to stronger and more adaptive offspring.

Overall, Red Barrenwort is a pollinator-friendly plant that can attract bees, butterflies, and other insects with its small flowers. To ensure efficient pollination and genetic diversity, it's best to plant Red Barrenwort alongside other showy flowers that provide a diverse range of nectar sources.

Red Barrenwort (Epimedium x rubrum) FAQ

What is Red Barrenwort?

Red Barrenwort is a flowering perennial plant that is part of the Epimedium family. It is a hybrid of two other Epimedium species, Epimedium alpinum and Epimedium grandiflorum.

In early spring, cut back any dead foliage and apply a slow-release fertilizer to encourage new growth. Once established, Red Barrenwort does not need to be divided or transplanted.

Are there any pests or diseases that affect Red Barrenwort?

Red Barrenwort is relatively pest and disease resistant. However, it may be susceptible to leaf spot or powdery mildew in humid conditions.

Can Red Barrenwort be propagated?

Red Barrenwort can be propagated through division in early spring or fall. Simply dig up a clump of the plant and separate the roots with a sharp knife. Transplant the divided plants to their new location and water thoroughly.

Can Red Barrenwort be used in landscaping?

Red Barrenwort can be a great addition to woodland gardens, rock gardens, or as a groundcover. It looks best when planted in groups of 3-5 plants. It pairs well with other shade-loving perennials such as Hosta, Astilbe, and Hellebore.

Planting & Care for Red Barrenwort (Epimedium x rubrum)

Planting

Red Barrenwort (Epimedium x rubrum) prefers partial to full shade and well-draining soil. It can tolerate full sun but is more likely to thrive in the shade. Plant it in spring or fall, either in raised beds or directly in the ground. When planting, space the plants about 12-18 inches apart, and water them deeply at planting time.

Watering

Keep the soil moist but not waterlogged during the growing season, typically from spring to early summer. Water deeply once or twice a week, depending on the weather conditions. In the late summer and fall, gradually decrease watering to prepare it for its winter dormancy.

Fertilizing

Fertilize the plant in early spring with a balanced fertilizer. Use a half-strength solution to avoid over-fertilizing, which can lead to weak growth. Repeat once every six to eight weeks until early summer.

Pruning

Red Barrenwort benefits from occasional pruning to remove any damaged or diseased leaves, stems, or flowers. Prune it in late winter or early spring before new growth appears to help promote a bushier, fuller growth habit.

Division & Propagation

Divide the plant in early spring before new growth appears. Carefully dig up the entire plant and gently separate it into two or three sections, each with a clump of roots and foliage. Replant the sections in well-draining soil at the same depth as before and water them deeply. Propagation can also be done by collecting and sowing seeds in the fall. Sow the seeds in rich, well-draining soil, and maintain moist soil until germination.

Pest & Disease Control

Red Barrenwort is generally resistant to pests and diseases, but it can be susceptible to spider mites, aphids, and powdery mildew. To prevent these problems, maintain good air circulation around the plants, avoid overcrowding, and water them at the base to keep the foliage dry. If needed, treat the plant with an appropriate insecticide or fungicide, following the label instructions.
