As the peak of summer begins to fade, many gardens start to lose their luster. However, late summer doesn’t have to signal the end of your garden’s glory. With the right selection of plants, you can maintain — or even enhance — the colour, texture, and vibrancy of your outdoor space well into autumn.

Here’s a curated list of top plants that thrive in late summer, adding beauty and resilience just when other blooms begin to wane.
