Blooming Now!

From fresh blooms to early autumn hues, the Gardens is bursting with natural wonders to explore!

It’s been a vintage year for roses at Hendrie Park — while past the peak of their second flush, delightful bursts of red, pink, white, and yellow roses as well as lovely companion plants still decorate the Rose Garden.

Next to the iconic Pollinizers sculpture, the Trial Garden beds are putting on a beautiful show of colour with sparkling impatiens, prismatic lantanas and pretty petunias.

Over at the Rock Garden, fall colours are slowly trickling in, with the Japanese Maple tree as fiery standout in the lower bowl. More blooms continue to flourish, including Cardinal Flower, Snowdrop Anemone, White Wood Aster, Joe-Pye Weed, Goldenrod and Lesser Calamint, all complimented by the collection of richly green coniferous trees. While Hibiscus are passing peak bloom, many are still providing stunning displays of colour and grandeur.

Enjoy some downtime and serenity down by the water feature, where waterlilies bloom over calm waters, and ornamental grasses including delicate Purple Love Grass and the fuller Tufted Hair Grass ‘Pixie Fountain’ make a captivating backdrop with the setting sun.

Laking Garden has a full autumn display around the cottage on the upper terrace, making it the perfect place for a fall photoshoot! More seasonal favourites are sprouting up in this garden, including pumpkins, gourds, kale and lovely textured grasses among the garden beds.

At the Arboretum, full trees offer shade for those exploring the wide-open garden — keep an eye out for the changing colours of the Maple, Oak and Linden trees as we move further into fall. And keep an eye out in the Synoptic Shrub Collection for Beautyberry, a fantastic fall shrub with richly coloured purple fruit.

Venture through RBG’s nature sanctuaries for amazing birding opportunities during migration season. Over 250 bird species can be seen over the course of migration season, and in the fall every trail hosts something special. The first burst of fall colours have begun along the trails, led by goldenrods and over 30 species of Aster, with flowers concentrated around Princess Point, the Arboretum and Rock Chapel.

Indoors, the Breezeway has also prepared an autumnal display that boasts plump pumpkins, chrysanthemums and decorative cabbagesCapsicum annuum ‘Black Pearl’, Solanum ‘Pumpkin on a Stick’ and Musa acuminata ‘Zebrina’, a species of banana tree, are all still part of the horticultural highlights adorning the surrounding beds.

In the Mediterranean Garden, the one-of-a-kind Bird of Paradise looks stunning as ever, and a rainbow of lantanas shine brightly among the deep greens of palm trees and aloes. Our Cacti and Succulent Collection is ready for a preview — only open on weekends at the moment, you can enjoy a range of varieties and textures among the collection, including some sky-high cacti and the critically endangered Golden Barrel Cactus!
