Seeds are expelled around by an explosion of their elastic capsule when touched at maturation.

Ancients thought  hawks used this plant to ameliorate their sight.

Leave a piece of land fallow and look what you get on the Island of Orleans  : a nice tapestry.

This flower was photographed late in summer on Saint Lawrence River shore.

Grows everywhere but prefers dry soils. The first time I saw this flower was near the railroad tracks. May be the last train had a dining car. 

Its pod arrangement look like a birdsfoot. In ancient times this pea family plant was used as an excellent fodder.  Alexander-the-great horses surely ate some of this nice showy plant !

Its name refers to its opening at setting sun. Is that really true ?

A somewhat rare flower who grows on dry rocky soils. May be its small thick leaves  are a water reserve. Its five pointed petals and its long spread-out stamens are characteristic.
