RBG’s Peony Collection
Peak Interest: June
One of RBG’s earliest signature collections, the Peony Collection began at Laking Garden in 1949.
Given its age, RBG’s collection offers a unique history of peonies, displaying a range of cultivars and hybridizer introductions from the 19th, 20th and 21st century. As a result, it is now one of the most diverse and unique peony collections in North America.
With a number of varieties with differing bloom times, there are iris to see for multiple weeks, often late may and early June.

Plan Your Visit to the Peony Collection
The peony collection is located at Laking Garden, one of RBG’s four formal garden areas. Herbaceous and Itoh peonies are displayed on the lower terrace, and a selection of tree peonies are located near the entrance Kiosk.
Getting to Laking Garden
1221 Spring Gardens Road, Burlington, L7T 1J8
Parking available in the upper parking lot (off Plains Rd. W.) or in the lower lot (Spring Gardens Rd.). NOTE though finding the upper lot is easier for those on their first visit, accessing the garden from this lot requires walking across a bridge and descending down a winding ramp. For those with accessibility concerns, we recommend using the lower parking lot.
Before departing, have a close look at a map of the area to familiarize yourself with the route; Spring Gardens Rd. (and the two parking lots) is bisected by a train track, and is NOT a through road.
- 10 a.m. to 8 p.m., last admission 7 p.m. (May 5 to Sep 4)
- Closed for the season (Sep 5 to Apr 30)

About RBG’s Peony Collection
Introduced in the late 1940s, the Peony Collection was planned by RBG Superintendent James Redman, who organized the plants around the existing the Iris Collection.
The collection has been laid out not only to display generations of flower diversity within the genus Paeonia, but also to highlight the amazing range of colours of cultivated peonies.
Peony cultivars can be divided into three main types: herbaceous, Itoh and tree peonies, all of which are featured in RBG’s collection.
Curator in the Collection
Curator Alex Henderson speaks with Jenn about what makes our peony collection at the Laking Garden unique, and why you should consider growing your own peonies at home. Watch the video to learn more!
A large portion of the collection is dedicated to herbaceous peonies featuring single, Japanese, anemone, semi-double, bomb and double flower types.
Herbaceous peonies are most commonly planted type of peonies in home gardens. They die all the way to the soil surface in winter and resprout in spring
Originating in China, tree peonies have a woody structure, they will lose leaves in winter but the whole plant won’t die down to the ground the way herbaceous peonies do. Most of RBG’s tree peony cultivated are on display near the entrance of Laking Garden
Itoh (hybrid) peonies are a cross between tree and herbaceous. They have a woody structure and regrow their leaves in spring. Itoh peonies produce the largest flowers of all the peony types.
Along with the Iris Collection, the bulk of the Peony Collection is also found on the lower terrace of Laking Garden. These display beds include Itoh and herbaceous peonies.
The History of RBG’s Peony Collection
Laking Garden is one of RBG’s oldest gardens, and the first to have herbaceous plant collections. The Peony Collection began in 1949 — the original peonies were acquired by the Niagara Parks Commission around the mid-1940s.
Over the decades since, various individuals have donated peonies and plant from their garden to RBG, including interested hybridizers. The Gardens has also sought new additions for its collection, resulting in a beautifully vast display of peonies that are a tribute to over 70 years of care and enthusiasm.
An Internationally Significant Collection
According to the American Public Gardens Association’s (APGA) Plant Collections Network, RBG has one of the most diverse botanical garden peony collections in North America. The extraordinary collection displays a number of peonies now found nowhere else.
