Common nouns: trille with large flower, trille grandiflore, in : broad-flowered trillium, white trillium .

Description

This typical plant of the érablière S of the North-East of North America often forms large colonies which paper the underwoods in spring. The solitary flower, from 5 to 10 cm in diameter, comprises three white petals with margin slightly corrugated, becoming pink pale with the age. It is drawn up with the top of a Verticille of three broad sheets rhomboïdes-ovals and acuminate, without petiole, gathered at the top of the stem. The fruit is a capsule resembling a bay red and becoming blue black with maturity.

Etymology

The name of the species comes from the Latin botany grandiflorum , with large flower.

Surface of distribution

South of the Ontario and the Quebec, New England, Michigan, Minnesota, Wisconsin.

Use

The starts-up can eat themselves cooked like vegetable, but this practice is disadvised since it generally results in the death of the plant. The rhizome and the fruit are not edible.

Others

The white trille is the floral emblem of the Canadian province of the Ontario. It also appears on the Drapeau free-Ontarian.

F. roseum with pink flower, that one especially meets in Virginia, and the shape with flower doubles `Flore Pleno' are very required.
