O’Brien said her neighbors also seem to appreciate the beds of native herbs and flowers in her yard. “That’s really not true because a lot of our native plants can take care of themselves and outcompete weeds.” “I think people think it’s too difficult, and that you might have to weed all the time,” Wrenn said. According to Wrenn, their most popular group activity has been just inviting the other members to one of their home gardens to see how this type of landscaping is done. The regional chapter has grown to 55 members in just a few months. “We’ve had some issues for some of our members, for people all over the country and in our closer-to-home communities where they are getting cited with codes for having weeds in their yard,” said O’Brien. The sale of popular, but invasive plants at nurseries and greenhouses, like Japanese barberry and Callery pear, is also a concern. Wrenn said they would like to see better regulation or a ban of some common pesticides. Wild One is also interested in public policy. The carbon-rich yard waste breaks down, releasing methane, a powerful greenhouse gas. Wrenn added that bagged leaves that end up at a landfill contribute to climate change. If people don’t want to leave the leaves where they fall, O’Brien suggests raking leaves and putting them in a designated spot that’s out of sight, preserving the insect life. “That leaf falls from the tree onto the ground.” “A lot of our vital pollinators overwinter by making themselves a cocoon inside a dried-up leaf,” she said. Fall leaves are also important for the ecosystem. She doesn’t cut the plants down in the fall because pollinators nest in the plant stems in the winter. “It’s beautiful and it’s covered in pollinators all summer, but then all through September and October, the goldfinches eat the seeds.” “A ll that mass in the middle there is purple anise,” she said, pointing to one of her flower beds.

Tamara O’Brien, the co-founder of the new chapter, who lives in Pittsburgh’s South Hills, has been replacing her lawn with native garden and vegetable beds for the last 15 years. The Environmental Protection Agency found that gas-powered lawnmowers and other lawn care equipment contribute to air pollution, including unhealthy particulate matter. Wrenn hopes the group can persuade people to eschew lawnmowers, too. Your Lawn Is an ‘Ecological Deadzone.’ The Case For Replacing It with Native Plants “In a lawn that’s made from one or two species of grass, you will really never see any sorts of insect life.” “For one thing, they are ironically biologically sterile, even though they may look very alive,” he said. Lawns, said Wrenn, are the most destructive element of traditional landscaping, a concept promoted by author and entomologist Doug Tallamy. “ We should garden in such a way that helps the Earth rather than harms it, “ he said. But he said, for him, there is an underlying philosophy.
It can be more manicured, or more wild and free-flowing. Wrenn said natural landscaping can be interpreted in many ways. They want to shift the public’s perspective about why they choose certain types of plants, and what the alternatives are. “We’re working to create demand for native plants and natural landscaping services so that they will become more widely available,” Wrenn said. and Midwest that advocates for landscaping and gardening practices that promote biodiversity. It’s a membership organization with chapters in the Eastern U.S. Wrenn said that is one of the reasons he co-founded the Western Pennsylvania chapter of Wild Ones: Native Plants, Natural Landscapes.
