Montbretia
Watch listCrocosmia x crocosmiiflora
The orange garden crocosmia that has escaped into hedge banks and coastal paths all over Gower, forming solid corm mats that nothing else grows through.
How to identify it
- Sword-shaped pleated leaves in dense fans
- Arching sprays of orange trumpet flowers
- Chains of corms just under the soil surface
Why it matters
- Excludes native hedge-bank and cliff-top flora
- Very persistent once the corm mat forms
How to control it
- Dig out every corm — leaving one restarts the patch
- Never tip crocosmia clearings over a hedge or on a lane
