An escaped ornamental, this fast growing aggressive weed has invaded the shores of Pigeon Lake. It grows between .6 to 2 meters tall rapidly out-competing other plants.
Once developed, the seed capsules are very brittle and explode upon contact.
This plant has been classified by the Alberta government as a prohibited noxious weed which means that it must not be allowed to exist on your property.
If you encounter any of these plants, help the eradicate program by following the protocol which has been developed at Pigeon Lake as an easy and effective means of removing it: Pick, Break and Drop.
By following this protocol, the chances of spreading the plant to other areas are reduced and will kill that plant. Do not pile the plants or dispose of them in a compost pile as they will continue to thrive.
Please report any plants found in areas away from the lake shore so that these areas can be monitored in futre years.
