In autumn/winter the foliage of Epimedium ‘Thunderbolt’ turns a fantastic chocolate red with lightning bolts of green flashing across them. The colour matures to mahogany, even purple in the winter sun.
The bright yellow flowers join the party in spring and last well. By this stage the leaves are becoming more green and the contrast is gorgeous. Epimedium ‘Thunderbolt’ is drought tolerant and doesn’t make too many demands. It is lovely and vigorous and in the right conditions can expand up to 20cm a year which makes it a great filler for dry shade.
Epimediums have a lot to offer, and the prosper in the most inhospitable of conditions, dry shade. They are clump forming, rhizomatous perennials native to woodland areas. They grow best in humus rich, well drained soils. Plant in a part shade to filtered light position.
Epimediums are good for planting beneath trees or shrubs such as Hydrangeas, in shaded borders, as shady ground covers or, in well cared for pots.
Fertilise and mulch Epimediums in winter, they love the soil to be rich in composting leaves so don't hold back with dumping them on when they fall in autumn. They spread by underground rhizomes, at a moderate rate, it is no brute. Divide your Epimedium clumps every 3-5 years and don’t forget to protect new foliage from the threat of slugs and snails.
Cut back your Epimedium foliage late winter or spring, to allow the new leaves and flowers to shine, just as you would a Hellebore/Winter Rose.
Epimediums are also known as Barrenwort, Bishop’s Hats and Horny Goat Weed.
