What Makes a Great Summer Garden Plant?

The best summer perennials do much more than simply bloom. They continue performing right through high heat, attract local pollinators, provide lasting color, and require relatively little maintenance once they are established in your soil.

The following five plants check every single one of those boxes.

2. Grape Crush Aster: Color When Summer Begins to Fade

Many gardens begin losing their momentum and looking tired toward the end of summer. Grape Crush Aster does the exact opposite. Its vibrant, rich purple blooms appear just when many other flowers are slowing down, helping you extend deep garden color well into the late season.
