An Edmonton senior is upset that contractors sent to remove noxious weeds from her property cut down her prized lilies instead.

Louisa Petty, 90, noticed the flowers were gone when she stepped into her backyard on Tuesday morning.

"I saw this carnage," Petty said on Friday. "I didn't see the high things that were coming into bud pretty soon. All the daylilies and there’s no weeds in here … just nothing. Everything cut off!"

Petty received a notice from the city asking her to remove creeping bellflower, a noxious weed, from her property.

She looked but couldn’t find the plants.

The city is allowed to take action under Alberta’s Weed Control Act so the contractor was sent to Petty’s property. But workers took out more than the weeds.

Petty received an apology from the city after she called to complain.

Ryan Pleckaitis, the city’s director of complaints and investigations, was at Petty’s home on Friday.

"I think the first thing is to get somebody here to clean it up," he said.

"I mean they are daylilies, they will grow back. We will look at whether or not we need to replace the flowers or provide some kind of temporary substitute for remainder of the summer."

Petty was pleased with this solution.

"Oh that would be wonderful," she said as she held out her hand to Pleckaitis.

The city also plans to review what happened.
