Western bracken fern, Bracken fern, Western bracken, Bracken
Dennstaedtiaceae (Bracken Indies-Almond Family)
USDA Symbol: ptaq
A very aggressive fern of worldwide distribution for dry woodlands. The only fern for most dry shade situations. Ideal for dry Post Oak (Quercus stellata) forests and pine forests. The tripartite, furry, silvery fiddleheads emerge in early spring. The roots colonize aggressively and extend deep in search of moisture, as far as 10 feet deep in some locations.

Soil Moisture: Dry , Moist , Wet
Soil pH: Acidic (pH<6.8)
CaCO3 Tolerance: Medium
Soil Description: Acid clays, loams, and sands, preferably poor and sterile
Conditions Comments: Does not tolerate flooding. Though tolerant of dry soils, it goes dormant during droughts that last more than a week or two and will begin to die if it doesnt receive rain for 3 months. Requires a lot of water to get it established, but once established, relatively drought-tolerant, persistent, and aggressive.
BenefitUse Ornamental: Great foliage groundcover for dry woodlands
Use Wildlife: Provides shelter to small animals
Use Food: EDIBLE PARTS: Unfurled fronds. Gather young, tightly furled fiddleheads in early spring as soon as they first appear. Remove brownish, papery scales by rubbing with the hands. Soak for several hours in lightly salted water. Cook for 20 minutes on low heat in a pan filled with about 1/2 inch water. Drain well and serve like greens. (Poisonous Plants of N.C.)
Warning: POISONOUS PARTS: All parts, fiddleheads (curled-up leaves). Low toxicity if ingested. Symptoms include weakness, high fever, incoordination, convulsions. Toxic Principle: Thiaminase, a proteinaceous enzyme causing a reduction in vitamin B1; also a glycoside. (Poisonous Plants of N.C.)
Interesting Foliage: yes
PropagationPropagation Material: Root Division
Description: Divide roots while plant is dormant.
Maintenance: Water regularly to get it established, then let it naturalize, watering only during extended droughts. Reduce watering if gets too aggressive. Cut back during winter so new spring growth will be unobstructed.
