About a month later—around late August—I went for a walk around the garden center just to browse, and I learned about adding winter interest and pops of color to the garden. I came across this really striking plant with white flowers. It blooms for quite a long time and stays evergreen over the winter without dying back completely, so when everything else dies back to the ground, these start blooming with tight erect spikes of tiny flowers. (I'm talking about the Heather / Calluna, by the way!). I picked up four or five of them to add along the front border, and even now, a few of them are still hanging on here and there looking good with their bright white blooms. I did notice that they really benefit from heavy pruning—it keeps the base from getting leggy and woody, helping them come back much more lush, dense, and full of flowers.
