I saw this Rose of Sharon (Hibiscus syriacus) popping up in this same spot off 9th St. below the Italian Market, 3 years in a row. This shot was taken in 2020, which was the last year I saw it there.

There are a lot of sources online that say Shetland is home to the endemic species Edmondston's Chickweed.
This is not the case - instead the island of Unst is the only global site for Cerastium nigrescens var. nigrescens, an endemic *variety* of the Artic Mouse-ear.
