Dryopteris 'Brilliance'

Dryopteris erythrosora 'Brilliance': Autumn Flame Fern

Uses and Benefits: 'Brilliance' shines as a colour accent in shady beds, woodland gardens, or container groupings. Its emerging fronds bring early-season interest, and its lustrous mature foliage provides a clean, tidy look through summer and fall. A fantastic fern for layering among hostas and hellebores, it holds up well to humidity and is notably deer and rabbit resistant. It’s a great choice for gardeners looking to add subtle seasonal drama with minimal upkeep.

Companion Plants: Echo the warm tones of Dryopteris 'Brilliance' with the deep burgundy foliage of Heuchera 'Palace Purple', the fragrant spring blooms and patterned leaves of Tiarella 'Sugar and Spice', and the soft golden flow of Hakonechloa macra. This trio weaves together contrast and harmony, offering a richly layered, shade-loving combination with enduring beauty.

Care Instructions: Keep soil consistently moist but not soggy, especially during hot or dry weather. Add compost or leaf mulch annually to improve soil structure and fertility. Remove any winter-damaged fronds in early spring to make room for fresh growth. Division is rarely necessary but can be done in spring if needed. Protect from harsh wind and intense sun for best colour and form.

History: 'Brilliance' is a selected form of Dryopteris erythrosora, commonly known as the Autumn Fern, and prized for its especially vivid new growth. Native to East Asia, this fern has become a favourite in North American gardens for its blend of ornamental value and adaptability.
