CALGARY -- Helen Amber says the city's crackdown on her wildflower garden is "silly" and she feels "harassed" by officials' threats to remove them.

City bylaw officers served the woman with a 24-hour notice to kill the plants or they will at Amber's expense because the blanket of blooms in her front yard are noxious weeds.

"I think it's silly," said Amber, from Sicamous, B.C., where she's studying the medicinal value of wildflowers.

The 65-year-old Parkdale resident has been given a series of notices by city bylaw officers to take care of the wild yellow and white daisies and purple flowers in her front lawn.

Amber said she wrote to top bylaw officer Bill Bruce and was told he would look into it, which left her surprised when the ultimatum came.

In a notice, dated July 20, Amber was asked to remove the Canada thistles, scentless chamomile, oxeye daisies and blue weeds from her property.

She then got the 24-hour notice on Aug. 3 to remove the wild plants or city crews will.

"I will feel that I'm being walked upon and not listened to and talked to properly," she said. "I feel like I am being harassed by the City of Calgary."

Kevin Leitch, a supervisor with Animal and Bylaw Services, declined to comment on the specifics of the case because the dispute is ongoing, but he explained the rules.

The Alberta Weed Control Act has identified which plants are considered noxious ones, and the plants Amber has in her yard fall under that list.

Leitch said property owners are given 10 days to control noxious weeds once they've been identified.

"Under the Weed Act it's quite clear, thou shall not have weeds, noxious or noxious prohibited weeds on your property," he said.

Grass and other herbaceous plants such as dandelions become subjects of enforcement if they grow more than 15 cm, except if they're in golf courses, natural park areas as well as well-maintained and cultivated gardens.

Eric, Amber's son, has been left to deal with the matter.

He said bylaw officers have been heavy handed on the matter.

"All little old ladies in the world love flowers," he said.

"Why the war on flowers?"

Amber said if the city goes ahead and destroy her garden, she may just plant more wildflowers because they're not high maintenance and don't require regular watering and chemical application.
