Asplenium antiquum 'Leslie' - Fougère nid d'oiseau Leslie, fougère antique Leslie

Asplenium antiquum 'Leslie', also sold as Asplenium ‘Lesley’, is a highly decorative bird's nest fern, prized for its curly chicory foliage that unfurls in a rosette like a verdant nest. This indoor fern brings a great deal of freshness to gently lit rooms while improving air quality. It is an original and decorative variety, but it has specific needs in terms of humidity and watering.

Asplenium 'Leslie' belongs to the Aspleniaceae family. It is a cultivar of Asplenium antiquum, a fern native to the humid forests of East Asia (China, Japan, Korea, Taiwan), where it grows as an epiphyte on trunks and in the forks of trees or on mossy rocks. It is known by several names: Leslie's antique fern, Leslie's bird's nest fern, or Lesly's Asplenium.

Leslie's antique fern is evergreen and exhibits a compact rosette habit, resembling a deep nest from the centre of which new fronds unfurl. At maturity, it reaches 30 to 60 cm in height and approximately 40 to 60 cm in width. The fronds are narrow, leathery, and glossy, of a fresh to medium green, often slightly lighter when unfurling. They are upright then arching, 30 to 50 cm long, and feature a very undulate and crinkled margin, sometimes crested at the tip, which gives the plant its characteristic "frilly" appearance. There is no flowering: like all ferns, Asplenium reproduces by spores borne on the underside of the fronds, but this phenomenon remains discreet in a pot.

Indoors, Asplenium 'Leslie' appreciates soft to medium light, without direct sun: a spot near a north or east-facing window, or behind a sheer curtain, suits it very well. The growing medium should remain constantly slightly moist, never waterlogged. This fern enjoys a high ambient humidity, ideally around 60 to 70%. It thrives between 18 and 24°C. Non-toxic to pets, it is suitable for homes with cats or dogs.
The rooms best suited to its cultivation are a bright bathroom, a well-lit kitchen, and also a living room or bedroom with a gentle atmosphere, away from radiators and draughts.

The 'Leslie' bird's nest fern can be placed in a terracotta or ceramic cache-pot, set on a shelf, a sheltered windowsill, or at the foot of a large plant like Monstera 'Thai Constellation'. It can be combined with Fittonia 'Mini White' with white-veined leaves, which shares its preference for filtered light and humid air. To enhance the tropical woodland effect, place it near the 'Artic Jungle' Boston fern (Nephrolepis) in a bright bathroom: the trailing fronds of the Boston fern and the curly rosette of the Asplenium create a lush display, ideal on a console or low piece of furniture, or in a row on a shelf.
