Pine Needle
noun
The pine leaves are not really leaves, they're more like needles, thus making this word pine needle.
松葉 is commonly used in compounds, such as 松葉ガニ (snow crab) or 松葉づえ (crutches).
If you know the readings of your kanji you'll know how to read this as well. The 葉 gets rendaku'd to ば though, so watch out for that.
