Native prairie plants are recommended for planting over mounds and drainfields. Nutrients in the wastewater are taken up by the plants, instead of entering the groundwater. Studies have shown that the roots of prairie plants do not clog septic system pipes. For septic systems that have received topsoil over the sand and gravel backfill use our Short Prairie for Medium Soils Mix.

All seed is Pure Live Seed (PLS). One PLS pound is defined as the weight of seed required to equal one pound of 100% pure, germinable seed. This is calculated based upon each seed lot's purity and germination tests. We track the ecotype origin of our seed inventory and provide this information at customer request.
