Monkeyflower (Mimulus guttatus). Beautiful but quite invasive, as it spreads along the bank of this Dorset chalk stream. #InvasivePlants #WildflowerHour @wildflowerhour.bsky.social

Pretty flower head of Small Teasel, Dipsacus pilosus, back lit by morning sun. Will grow taller than Wild Teasel and soon scatter its seed far and wide.

Hardly any Himalayan Balsom ( #InvasivePlants ) to be seen today. The good people of CURB (Clean Up the River Brent) have been doing lots of bashing.

Scourge of railway infrastructure, the ubiquitous, beautiful but invasive Buddleia. It costs the UK an estimated £1 million in removal costs annually. Note bonus Swallow photobomb 😁 #InvasivePlants #WildflowerHour @wildflowerhour.bsky.social

Non-native Gunnera, Isle of Barra. From 1 plant in the late 90s to 700+ today, this wannabe Triffid is thriving in the damp peaty soil but shading out native flora including rare Irish Lady's Tresses. There's talk of an eradication scheme; it can't come soon enough. #InvasivePlants #wildflowerhour
