Towns, villages and places in this area
Each place has its own local guide with a map, area facts and the plants to watch for.
What grows here
Japanese knotweed
Swansea is one of the worst-affected places in Britain. Knotweed dominates back lanes, railway embankments, riverbanks and derelict plots across the city, and it is the weed most likely to affect a mortgage or a sale.
Shoots March–April, peak growth June–August, canes die back brown in winter
Japanese rose
A thorny dune invader. It binds and over-stabilises mobile sand, which is exactly the wrong thing for Swansea Bay and Gower dune systems that depend on bare sand.
Flowers June–September, hips autumn
Wall cotoneaster
Birds carry the berries from gardens straight onto Gower's limestone cliffs and grasslands, where cotoneaster smothers some of the rarest plant communities in Wales.
Flowers May–June, red berries autumn into winter
