Blossom Hill Nursery
Delphiniums and Peonies

Celebrating 20 Years of Growing Excellence

As we prepare for our 20th anniversary year, the ground is covered with a fresh blanket of snow that has our peonies, delphiniums and other perennials safely snuggled in for a new start in the spring. Looking back we have much to celebrate and build upon for future years.

In 2013 at the Canadian Peony Society Convention in Rosemère, Quebec one of our entries, Garden Treasure (a yellow intersectional peony) was selected as the Grand Champion. We had 6 of the 12 winning entries on the Court of Honour. This is the second time Hazel has won this honour. Her entry of Bartzella was selected as the Grand Champion in Montreal in 2009. Hazel also had a Court of Honour ribbon for Black Swan at the Oshawa Peony Festival in 2013 among many other ribbons. When we travel to the APS Conventions, Hazel has been competing and winning ribbons in the flower shows including at Longwood Gardens, Philadelphia in May 2013.

Blossom Hill specializes in delphiniums and peonies. Our perennials including delphiniums and peonies are grown in our own fields. We do NOT grow or sell micro-propagated peonies. We continue to offer mail order services to Canadian and USA destinations, as well as direct sales from our home.  Many years ago, we added British strain Delphinium elatum to our gardens and discovered that they possess stronger stems, larger florets and are also hardier than other Delphinium elatum. We have been hybridizing our own stain ever since.

We are excited to include many new varieties of peonies to this year’s catalogue. Each year more varieties reach maturity in the field, so they can be added to the catalogue. We now have more than 600 varieties (4500 plants) including species, tree, herbaceous and Itoh (Intersectional) peonies. The collection produces an amazing show. Visitors are welcome at the nursery to view our many perennial beds and trial gardens. The main show for peony flowers is the month of June, with some blooming in late May and early July. Delphiniums tend to flower from mid-June to mid-July and again in late summer and autumn.

In order to preserve the peony collection for future generations, we have donated one root of each variety of our peonies to Whistling Gardens in Norfolk County.

We open Sunday, May 17th until September 30th but we will have reduced hours. We will be open fewer days to allow more time for maintenance and breeding.  To highlight the peak bloom seasons we are once again inviting everyone to a Peony Open Garden event, Saturday June 21st, 2014 and a Delphinium Open Garden event, Saturday July 5th, 2014. Business hours are by appointment or chance. Please contact us before planning to visit.

Our catalogue continues to be in a plant list format without pictures to reduce printing expenses. However, photographs of many of our plants are posted on our website for your information and enjoyment.
