3 While touching the sap is not likely to cause you any harm (you might get a rash and irritation), products made from sanguinaria extract are very dangerous. The sap contains sanguinaria, a potent toxin which attacks and destroys animal cells. Bloodroot ( Sanguinaria canadensis) Nichole Ouellette, CC BY-SA 4.0, via Wikimedia Commonsįound in: Deciduous and mixed wood forests, along freshwater shorelines, and sometimes in meadows and clearings in ON, QU, NB, NSīloodroot ( Sanguinaria canadensis) gets its name from the red-orange sap that is found in its stem and roots. On average, it takes seven years for a trout lily to produce a flower! 2 Individual flowers only last for a few days before they wilt, but the leaves can persist for months. Trout lily gets its common name from its speckled leaves which are reminiscent of the brown trout or brook trout. Also referred to as dogtooth violet, the plant derives this name from its bulb, which resembles the shape of a canine’s tooth. The leaves emerge before the flowers, and they are an important source of food for white-tailed deer. Young plants have one leaf and older plants have two. You’ll often find trout lilies growing in large colonies, forming a dense carpet on the forest floor. A few days later, armed with a field guide, I went back to find that many of the plants had bloomed yellow bell-shaped flowers. The ground was blanketed by unfamiliar waxy leaves, mottled with green and brownish-purple patches. The first time I saw trout lilies ( Erythronium americanum) I was walking through the Ottawa Greenbelt. Trout Lily ( Erythronium americanum) Trout lilies found along the Maliseet Trail in New Brunswick.įound in: Deciduous and mixed wood forests in ON, NB, PEI, NS This germination strategy, known as myrmecochory, is common among all the other ephemerals on this list. As a result, the seeds are dispersed from the parent plant and can germinate in new locations. The ants eat the elaiosomes, but do not consume the seeds. 1 Once pollinated, the flower becomes a fruit that contain seeds with a fleshy appendage called an elaiosome, which is rich in lipids, proteins, and other nutrients.Įlaiosomes are a valuable source of nutrition and attract ants who carry the seeds back to their nests. The plant’s distinct leaves are basal, growing from the base of the plant, and have a fern-like appearance.īees, specifically bumble bees like Bombus bimaculatus and Bombus affinis, along with honey bees, pollinate Dutchman’s Breeches. Here are five ephemerals to look for this spring: Dutchman’s Breeches ( Dicentra cucullaria) Dutchman’s Breeches in the Ottawa Greenbeltįound in: Hardwood and mixed wood forests in MB, ON, NB, NS, PEIĭutchman’s breeches ( Dicentra cucullaria) gets its name from the distinctive shape of its delicate, white flowers, which resemble the trousers worn by Dutchmen in the 17th and 18th centuries. Many have evolved specialized storage organs such as bulbs, bulbils, corms, and rhizomes that allow them to store nutrients and energy during the growing season to survive their dormant period. Once the forest canopy fills out, the ephemerals wither and die back.ĭespite their short lifespan aboveground, many spring ephemerals have complex lives that span multiple years, with different growth stages occurring underground and aboveground. It’s just enough time to grow, bloom, and produce seeds. By making an early appearance, they take full advantage of available sunlight before the trees and understory leaf out. This allows them to survive the shady conditions of deciduous forests. Spring ephemerals, as their name suggests, are short-lived plants that complete their lifecycle in just a few weeks. Once they arrive, they’re only here for a few short weeks, so you have to keep an eye out for them.īelow, you’ll find more information about these fascinating plants, their role in the ecosystem, and tips for locating them. In Eastern Canada, from April to June, you can spot a range of ephemerals, including Dutchman’s breeches, trout lilies, bloodroot, trillium, and spring beauties. Their appearance signals the end of winter and start of the growing season. Spring ephemerals are some of the first wildflowers to bloom in early spring.
