Invasive Non-native Species

Monkeyflower Mimulus guttatus

Monkeyflower, Mimulus guttatus is a tall, upright plant which produces large, yellow flowers, sometimes with orange markings. It is usually found in wet habitats, growing along streams, ditches, rivers and lakes, in wet pastures; and occasionally on disturbed ground. A native of North America, it has been present in Britain since the mid-19th century.

In suitable habitats it can form very dense stands, possibly to the detriment of the local native flora. Introductions into new areas could be prevent by gardeners and horticulturists adopting the Be Plant Wise guidelines.
