Is your garden starting to look dull and lifeless as summer progresses? If so, add some visual interest by planting summer flowering perennials!

Many perennials have a short flowering period, especially compared to annuals. If you want your garden to look its best during the summer months, there are certain perennials you can plant.

Here are some of our favourite perennials that will add colour, texture, and attract pollinators to your garden throughout July and August. Don’t forget that it is important to keep up with deadheading and fertilizing to encourage repeat blooming!
