A garden in NY City, above, pic from Urban Greenery 
In Toronto, above, pic from Urban Greenery Vine on the wall is a vertical lawn. Can you imagine the birds, butterflies, fragrance, sounds, coolness, privacy, pleasure, retreat, these little gardens provide? Puttering about in the gardens creates stronger ambient community ties and higher property values.Discovered the pics above on a fabulous blog, Landscape Urbanism. The pictures, words, intellect are delightful.
