Kalamazoo's 2012 wildflower season seems to be near its peak. Many flowers are blooming earlier than usual despite our recent cool temperatures. Flowers at their peak this week include: Squirrel Corn (Dicentra canadensis), Trillium (Trillium grandiflorum) , Wild Phlox (Phlox divaricata), Blue-eyed Mary (Collinsia verna), and Celandine poppy (Stylophorum diphyllum).
Marsh Marigolds (Caltha palustris) and Spring Beauty (Claytonia virginica) continue to blossom although they are past their peak time.
Other plants in flower now include Trout lily (Erythronium americanum), Jack in the Pulpit (Arisaema triphyllum), and various spring violets. Wild geraniums (Geranium maculatum) are starting to bloom
