Flowers, Trees and Shrubs Images of plants from Northwestern Ontario and other areas I’ve visited. [Show slideshow] Catkins of Manitoba Maple - also known as boxelder - from a tree in our front yard. The emerging leaf of a red maple tree. Female cone of a tamarack. Adaffodil from the garden aging gracefully in a vase inside our house. Bunchberry is one of the most common flowers in spring in northwestern Ontario. Yellow lady's slipper orchids, which I've never seen inQuetico, are found in a few places around Thunder Bay, Ontario. Mullein, here seen along the railroad tracks near Kawene, Ontario, is an introduced species that thrives in disturbed, sunny places.
