Small-space gardening doesn't have to mean limited planting. In fact, having a window box is sufficient space to create a vibrant display that lasts from spring to fall – especially when you choose the right flowers.
If you're feeling stumped for inspiration for spring window box ideas, then turn your attention to window box flowers to plant in April. Adding these blooms now will reward you with a bright display that offers color right through summer to fall. You don't need a huge window box either, as there are lots of compact flowers that will thrive in a vessel the size of this IKEA white window box planter.
