Dryopteris koidzumiana – This unique fern loves warmth, so patience is required for it to start growing. But once it does, new fronds emerge with their brilliant color through summer into early fall. Plant in a location with bright, open shade to a half-day of morning sun and rich soil with regular watering during dry weather.
This species does not bother that much about the soil type but prefers the climate of areas without the extremes of temperatures.
Dryopteris koidzumiana (syn. D. erythrosora var. koidzumiana) – This close relative of the Autumn Fern (Dryopteris erythrosora) was introduced in the early 1990’s and features brilliant coppery-red new fronds. It may be slow to enact new growth in early summer and is evergreen in milder regions. The fronds mature to a semi-glossy deep green. When the new growth emerges, the contrast of the unfurling, reddish new foliage is dynamite against the green of the fronds. Species is similar to Dryopteris erythrosora but with much deeper, darker red coloration… outstanding as a specimen plant in the woodland garden!
