Osmunda regalis
Also called European Royal Fern, Green Fern, Flowering Fern, Regal Fern
Royal fern is a large deciduous fern native to Europe, North Africa and West Asia, growing in woodland bogs and stream banks. Its key to success is consistently moist, acidic soil and shelter from drying sun.
Osmunda regalis, or royal fern, is a species of deciduous fern, native to Europe, North Africa and West Asia, growing in woodland bogs and on the banks of streams. The species is sometimes known as flowering fern due to the appearance of its fertile fronds.
Osmunda regalis is widely cultivated in temperate regions. The species and the cultivar 'Cristata' have both gained the Royal Horticultural Society's Award of Garden Merit. Osmunda plants should be planted in preferably acidic, moist soil, associating well with other large moisture-loving plants such as Rodgersia and Gunnera. However, it tolerates a range of soil and climatic conditions.
The native range of royal fern is throughout Europe, North Africa and the Middle East as far as Iran, from Norway south to Algeria. It is listed as introduced in New Zealand, but its presence throughout North America is based on the taxonomic uncertainty about whether Osmunda spectabilis should be considered a separate species or not.
