Usually found in shady woods, several patches of this low, colony-forming perennial can also be found in the Central Experimental Farm's (CEF) Fletcher Wildlife Garden.  Hidden below the leaves, solitary flowers bloom in early spring at ground level.

The yellow trout-lily is a spring ephemeral, with flowers poking through winter leaf cover for a few weeks in early spring.  Once leaves are on the trees and the canopy closes, trout lilies disappear for another year.

The Jerusalem artichoke is a species of sunflower whose  tuber is enjoyed as a root vegetable.  This plant was a "volunteer" in the artist's city garden, possibly planted by a bird or a gust of wind. It blooms in late August through September.
