Polystichum setiferum ‘Herrenhausen’: A Distinctive Soft Shield Fern Herrenhausen
The Polystichum setiferum ‘Herrenhausen’ stands out among ferns for its uniquely detailed fronds and compact growth habit. This cultivar brings year-round structure and refined texture to shady garden spaces.
Physical Characteristics
‘Herrenhausen’ grows in a neat, arching form reaching 60-75cm (24-30 inches) in height and spread. The finely divided fronds create an intricate lacework pattern that catches light beautifully. Each frond displays multiple layers of small leaflets, giving the plant remarkable depth and texture.
The new growth emerges bright green in spring, developing into a rich forest green as it matures. The fronds maintain their colour through winter, making this fern an excellent choice for year-round interest.
Growing Requirements
This adaptable fern thrives in partial to full shade, making it perfect for north-facing borders or woodland gardens. It grows best in rich, well-draining soil that stays consistently moist but never waterlogged.
‘Herrenhausen’ withstands temperatures down to -20°C (-4°F), showing excellent hardiness throughout the UK. It appreciates shelter from strong winds to maintain its pristine appearance.
Garden Uses
The compact size and evergreen nature of ‘Herrenhausen’ make it versatile in garden design. It excels in shaded borders, woodland settings, and container arrangements. The detailed fronds provide excellent contrast against broader-leaved plants.
This fern works particularly well near water features, where increased humidity benefits its growth. It also makes an excellent understory plant beneath trees and larger shrubs.
Seasonal Interest
Spring brings fresh lime-green growth that unfurls gradually, creating weeks of dynamic interest. The mature fronds provide reliable structure through summer and autumn. Winter reveals the architectural quality of the plant, especially when frosted.
Care and Maintenance
‘Herrenhausen’ needs minimal maintenance once established. Remove any damaged fronds in late winter before new growth begins. Keep the soil consistently moist, especially during dry spells.
A thick mulch of leaf mould or garden compost in spring helps retain moisture and adds nutrients. Container-grown specimens need regular watering and occasional feeding during the growing season.
