(Tiarella trifoliata)
The Foam Flower is a pretty woodland plant that has inspired gardeners to grow it at home, for its blooms, and for its ability to provide good ground cover. Vancouver Island woodlands boast a variety of wildflowers that light up the ground with their pretty blooms. Some are like little gems that are best appreciated close up, while others form a brilliant carpet across the forest floor that can take your breath away from a distance.
These flowers have white blooms that grow on a spike that rises above large heart-shaped or maple-like leaves that form an attractive ground cover.
The western Foam Flower grows primarily along the BC coast into Washington and on all of Vancouver Island. The flowers are a source of food for Canadian wildlife. Their seeds and leaves feed birds, such as the ruffed grouse, while flowers offer pollen and nectar to local pollinators.
This is not Tiarella cordifolia. It should be Tiarella trifoliata.
