Field Notes

[ growing · ecology · siting · care ]

Settlers used it as a folk-remedy snakebite cure (it doesn't work). Indigenous Americans wove the long fibrous leaves into shoes — 8,000-year-old sandals from Missouri caves prove the tradition. Tough, deer-proof, and structural in any prairie planting.

Why it's on this list: unmistakable architectural prairie native · spiky white globes. Part of Rooted Revival's NE Oklahoma plant catalog — natives, ecologically positive non-invasive cultivars, and food crops worth growing in the Tulsa region.

Companion Planting

[ guild · polyculture · cross-layer pairings ]

In a dry mixed-grass prairie planting, rattlesnake master pairs naturally with: new jersey tea (Ceanothus americanus), big bluestem (Andropogon gerardii), cowpea / black-eyed pea (Vigna unguiculata), black-eyed susan (Rudbeckia hirta), buffalograss (Bouteloua dactyloides), and compass plant (Silphium laciniatum).

Combine rattlesnake master with the warm-season grasses listed above for a self-sustaining matrix.
