After thoroughly double-digging my fruit plot before planting, I've discovered a huge docken has just appeared through the thick mulch.
He surveyed the grounds with their hen-houses, rust-bound corrugated iron sheds, broken down tractors, potato patches and clothes poles chest high in dockens with full heads of seeds.
Origin
Late Middle English: apparently from Old Englishdoccan, plural of docce(see dock4).
