My newest favorite place for garden inspiration is the site GardenPhotos.com. Its a stock photography site that is simply overflowing with amazing gardening ideas, shot beautifully.
My current favorite is this boxwood hedge with the wisteria and alliums jutting up from it. So cool.
The site allows you to put in keywords so you can search just about anything your heart desires for photo inspiration.
(the author of this photo explains the planting specimens are “Pink Wisteria trained as standard against wall, with Buxus boxwood at base, and Allium ornamental onion bulbs and Lavandula stoechas Spanish lavender for pink, lavender, purple color theme in courtyard garden.”)
