Okay, we're ready for the photos of the space where you want to bring color. Think of these as the 'Before' photos; they don't have to be beautiful, just so we can get some idea of the area, sun/shade, slope, existing plantings like trees/shrubs, etc. What color flowers make your eyes happy? Some folks like to plant to attract butterflies or hummingbirds, etc.
Off hand I would suggest planting some annuals for quick color while you wait for the perennials and bulbs to mature and bloom.
