Ontario’s trilliums and where to enjoy them

Ontario Parks is recognizing iconic Canadian species this year to celebrate Canada’s 150th birthday. Today’s post comes from Assistant Zone Ecologist Pilar Manorome.

Spring is probably my favourite season as it brings new life to our parks in the form of migrating birds and emerging spring ephemerals, giving our forests’ their long awaited pops of vibrant colours and contrast. One of our visitors’ favourite sights is Ontario’s provincial flower, the White Trillium, as their blooms blanket the forest floor.

Most people know of the White Trillium — also referred to as Wake Robin or Large-leaved Trillium — as Ontario’s provincial flower. This is the flower featured on many of our provincial documents, from health cards to driver’s licenses.

Here are the top five fun facts about this iconic Ontario species:

1. Three is the magic number with trilliums

They have three broad leaves, three small green sepals, three petals, and a three-sectioned seedpod. Even their genus name, trillium, refers to this phenomenon.

2. Trillium seeds are primarily dispersed by ants

This dispersal method is known as Myrmecochory (try saying that three times fast!).

Ants are attracted to the protein-rich elaiosome on the seeds of trilliums, which they eat after carrying the entire seed back to their nests. The actual seeds are not harmed during this process, and are later discarded to grow a new plant.

3. The White Trillium is a favourite food of White-tailed Deer

In fact, many of our provincial parks use annual trillium surveys to understand the population of White-tailed Deer and their effect on the biodiversity of our forest’s understory.

4. If you pick a trillium, the plant may not have enough energy to survive throughout the winter

As a spring ephemeral, trilliums have a few short weeks in the spring to collect as much sunlight and nutrients as possible to be able to survive for the rest of the year.

If you pick a trillium in the height of its flowering glory, it may not be able to collect enough resources to survive.

5. There are five native trillium species found in Ontario

They are: White Trillium, Red Trillium, Painted Trillium, Drooping Trillium, and Nodding Trillium.

All are found in the understory of rich, deciduous, or mixed, forests. The Drooping Trillium is actually a species at risk here in Ontario primarily due to habitat loss and degradation.
