Trillium erectum, the red trillium, is a species of flowering plant in the family Melanthiaceae. It is a spring ephemeral plant whose life-cycle is synchronized with that of the forests in which it lives. It is native to the eastern United States and eastern Canada from northern Georgia to Quebec and New Brunswick. Like all trilliums, it has a whorl of three bracts (leaves) and a single trimerous flower with three sepals, three petals, two whorls of three stamens each, and three carpels (fused into a single ovary with three stigmas). It is a perennial plant that persists by means of an underground rhizome. Trillium erectum has carrion-scented flowers that produce fetid or putrid odors purported to attract carrion fly and beetle pollinators. This T. erectum flower was photographed in Stephen's Gulch Conservation Area in Ontario, Canada.

Maple syrup is a syrup usually made from the xylem sap of sugar maple, red maple or black maple trees. In cold climates, these trees store starch in their trunks and roots before the winter; the starch is then converted to sugar that rises in the sap in the spring. Trees can be tapped by boring holes into their trunks and collecting the sap. This is processed by heating to evaporate some of the water, leaving the concentrated syrup. Maple syrup was first collected and used by the Indigenous people of North America; the practice was adopted by European settlers. Quebec, Canada, is by far the largest producer, making about three-quarters of the world's output. The syrup is graded based on its density and translucency. Maple syrup is often eaten as an accompaniment to food, as an ingredient in baking and as a sweetener and flavouring agent. Maple syrup and the sugar maple tree are symbols of Canada and several US states, in particular Vermont. (Full article...)
