An invasive, non-native plant.

This is an extremely popular garden plant, widely grown for its sprays of reddish orange flowers that appear in late summer. It’s most usually found on roadside verges and hedge banks, along cliff tops and woodland edges and on waste ground where garden plants are discarded.

What's the problem?

Although viable seed is produced, most reproduction is vegetative from underground corms and long creeping rhizomes; small fragments of root readily become established in the wild. Spread can then be rapid, resulting in dense stands at the exclusion of all other vegetation. It’s increasing rapidly and is especially frequent in the west and around coasts; in western Ireland whole roadsides can be densely carpeted for miles on end.
