If you do a Google search for Trillium you are likely to come up with all kinds of business websites that incorporate the word Trillium in the website or business name; everything from Trillium real estate to Trillium software to Trillium fiberfuels. Is that last one firewood? Perhaps they name themselves Trillium something to take advantage of the flowers beauty or maybe the company was started by three people or maybe they had three sticks of firewood to sell.
One might ask, just what is a Trillium? Literally, a Trillium is a tri-flower because of most of its parts grow in threes or multiples of three. It is a plant of the Lily family that springs from a rhizome. A rhizome is a ball of roots or a spike root. Each year the rhizome grows a single scrape. A scrape is leafless flowering stem or spike. The above ground parts of the Trillium that grow from the scrape consist of a whorl of three leaves and a tri-flower. The tri-flower has three bracts. A bract is a modified or specialized leaf, especially one associated with a reproductive structure. Trillium tri-flowers have three petals, three sepals and a multiple of three stamens.
