The handsome green leaves have a marvellous mottling of mahogany, aging to soft green through summer. It has good vigour and is lovely and tough. A semi evergreen form.
The foliage is topped with plenty of large, sulphur yellow flowers, with white spurs and bronzed sepals. They open early spring to summer.
Epimedium ‘Flowers of Sulphur’ was bred by Robin White, it is a cross between Epimedium flavum and E. ogisui. It is a herbaceous variety.
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.
