At the start of April, you’re welcomed to RBG Centre by a carpet of Crocus across the Main Entrance lawn. Tips of spring bulbs can be spotted coming up throughout the display beds which is a welcome sign assuring that bloom season is right around the corner.

While strolling through Hendrie Park, keep an eye out for low blooms such as Netted Iris, Pasque Flower, and Hyacinth. For a real treat, be sure to loop through Kippax Garden to see the early spring wildflowers such as Trout Lily and Hepatica bloom.

After the spring thaw, Rock Garden‘s winding and sloped garden paths are open again to explore! Here you’ll find Witch-hazel, Winter Aconite, Rockcress, and Forsythia blooming in April. Towards the end of the month be on the look out for the first flowering cherry blossoms of the season!

From delicate and ephemeral wild plants and flowering trees to beautiful migrating birds, every spring visit to the Arboretum brings a new adventure. The first of the flowering trees and shrubs are the Red Maples, Viburnum, and Cornelian Cherry Dogwood, and Star Magnolia. As an access point to many wonderful nature trails, you’ll also discover forest wildflowers coming into bloom including Bloodroot and Hepatica, while the woodland shrub American Hazelnut flaunts its brilliant yellow catkins.

At RBG’s What’s In Bloom page, you will find estimated bloom times / months of interest for several RBG’s collections. Please bear in mind that if we experience an early or late spring, bloom times could shift up to 10 days earlier or 10 days later.
