I wanted to create an oasis for butterflies, birds and other pollinators in my urban setting and eliminate all of the grass growing in my front and backyard. (It was great to get rid of the lawnmower too!) I also wanted to grow native edible and medicinal plants.
I also love the community it brings... when I'm out in the garden, almost everyone who passes by has a story to share about how they use certain plants in their homeland, or offer a sweet comment about feeling as though they're in the country whenever they walk by my garden. I never experienced that when I was mowing the lawn!
