What Blooms in August?

Note: this is a general guide of what typically blooms this month at RBG. Bloom periods may vary by up to 2 weeks. For the best view of what’s blooming right now at RBG, see the current photos on RBG’s Instagram, or find the “Bloom Watch” section on the What’s in Bloom page.

The summer heat and sunshine brings out the pollinators as the gardens burst with bright colour and cooling foliage all August long! Our gardens are celebrating the synergy between sports and nature through a series of floral displays! Each garden area pays tribute to this dynamic connection with its own unique theme.

Over in Hendrie Park, the Helen M. Kippax Garden bursts with pollinator-friendly native plants and their cultivars, including Coneflower, Bee Balm, and Blazing Star. In the Rose Garden, individual Rose varieties continue to pop throughout the month, while some summers will gift us another full flush! Between the Rose blooms, spot striking companion plants like Crocosmia, Pale Purple Coneflower, Stonecrop, Lindheimer’s Beeblossom, and Verbena bonariensis.

Lush blooms await you throughout the Rock Garden, including Cardinal Flower, Shrub Roses, Goldenrod and Woodland Sage. Russian Sage looks particularly striking as tall, pink Hibiscus flowers flourish behind it. Sitting by the water feature is the best way to cool down on a hot day, and it’s a great spot to enjoy the Water Lily and watch bees and butterflies flutter around blooming perennials.

Explore the nearby trails for signs of wildlife and keep an eye out while walking through the wetlands; Blue Vervain, Pickerel Weed, cattails and other marsh plants are flourishing.
