The story
Leadplant is the grey-leaved shrub of the tallgrass prairie, with roots that can go down fifteen feet. Plains peoples brewed its leaves as a tea, and settlers called it prairie shoestring for the way those roots snapped under the plow.
Planting
Full sun and well-drained soil, the leaner the better. Start with a small plant or sow scratched seed in fall.
Growing
Patience: it spends its first years building root. No feeding; it makes its own nitrogen.
Harvest and use
Purple spikes with orange pollen in July, a favorite of native bees. A sign of prairie that was never plowed.
What to watch for
Rabbits and deer browse young plants. It is slow to bloom from seed.
