Robust Male Fern
Dryopteris filix-mas 'Robusta'
|Description||This vigorous western U.S. native is widely adaptable to any shady, cool and moist spot in the garden or woodland. A fairly compact selection with long, leathery, emerald green fronds that are upright and stately. Produces a flush of new, deep green fronds each spring. Semi-evergreen; retains its foliage well in cold weather.|
|Watering||Keep soil moist, but not soggy.|
|Blooms||Prized for foliage.|
|Mature Size||Quickly forms foliage clumps 4 ft. tall, 2 ft. wide, or wider.|
|Landscape Use||Border, Container, Ground Cover, Edging|
|Design Ideas||A perfect space filler to flesh out shade gardens and landscapes under large shade trees or groves. Exceptional for filling gaps in rock waterfalls where shade prevents other plants. A good problem solver for narrow sideyards and fleshes out difficult north facing foundation planting.|
|Companion Plants||Azalea (Azalea); Camellia (Camellia); Japanese Forest Grass (Hakonechloa); Rhododendron (Rhododendron); Astilbe (Astilbe)|
|Care||Provide enriched, slightly acidic, well-drained soil, with shelter from drying winter winds. Water deeply, regularly during the first growing season to establish root system; once established, water regularly to maintain evenly moist soil. Fertilize regularly during growing season. Cut back old fronds after new growth begins in spring.|
|Lore||In ancient Europe, ferns were often associated with incantations and spells granting one invisibility because the plants lacked seeds and seemed to magically appear. Male fern is grown commercially as an anthelminthic, to expel worms.|
