noun
goat willow; pussy willow
Refers to the tree species Salix caprea, known for its soft catkins. Common in botanical and everyday contexts.
春になると、バッコヤナギの花穂がふわふわと揺れる。
In spring, the catkins of the goat willow sway softly.
The name likely derives from the Ainu word for this willow, with 柳 (yanagi) added as a Japanese suffix meaning 'willow'. The kanji 跋扈 (bakko) are ateji used for their sound, not meaning.
