A majestic garden fern, Osmunda regalis 'Purpurascens' (Royal Fern) is a tall, robust, deciduous fern of upright, vase shape habit forming a large rosette of elegant, broadly divided fronds. Emerging reddish-purple in spring, they are crowned with rusty-brown fertile flower spikes at their tips, thus giving rise to the common name of 'Flowering Fern'. The lovely foliage matures to bright green in summer before turning shades of gold and russet in fall, adding visual interest in the garden. Low maintenance, pest and disease free, Royal Fern is a great asset for very wet sites!

  • Clump-forming, it easily grows up to 2-4 ft. tall and wide (60-120 cm).
  • A part to full shade lover, it is best grown in fertile, humus-rich, consistently moist, well-drained soils. Do not allow the soil to dry out. Can grow in full sun if given plenty of moisture. Will tolerate alkaline soils if fibrous compost is added.
  • This plant is a great choice for shady beds and borders, cottage gardens, woodlands or along streams, ponds or water gardens.
  • Rabbit and wet soil tolerant!
  • Dead or damaged fronds may be removed as necessary.
  • Propagate by sowing spores as soon as ripe or by division in early spring or fall.
