Canaigre - Dock
These large showy plants grow in sand dunes and other very dry areas.
They have very deep roots to sustain the large leaves.
The native Americans used the plant as food, and as a medicine.
The young leaves can be cooked as a pot herb, and the stems are like rhubarb.
The crushed roots are effective when used as a poultice on a wound, to inhibit infection.
The flowers are small and inconspicuous. As the seeds mature, three of the sepals
on each flower enlarge to form a winged fruit around each seed. The species name hymenosepalus
means "membranous sepals".
