Another version on rain gutter gardening. Want to grow a salad garden but have no room? Try gutters! Affix them to a fence, slope them for drainage, and voila! Of course,for this I'd need a backyard wider than a hallway.
Stargazer Lilies, White and Blue Dendrobium Orchids, Good idea for centerpieces bouquet. I would switch the blue flower for either blue hydrangeas or maybe even blue white forget-me-nots for a lighter blue, pretty! But no lilies!
