The answer to last week’s mystery is Northern sea oats, Chasmanthium latifolium, pictured in photo #2.
Flat, green “flowers” develop on the arching stem tips from July through September. The flower heads are alluring and a slightest breeze will send flower heads fluttering on their stems. In fall, they become tan before the foliage turns to a copper color in early winter.
Snow adds eye-catching appeal to sea oats. The flowers gradually shatter ito make way for new spring growth, providing almost a full year of interest.
