Attachment B, 2026 Standard Pollinator Seed Mix.xlsx

This file is a technical specification document for the Kentucky Transportation Cabinet (KYTC) Standard Pollinator Seed Mix, detailing the precise botanical composition required for a one-acre wildflower planting in Kentucky's Statewide Wildflowers Seeds and Services procurement. The seed mix comprises 27 native plant species and oats, with specific percentages and pound measurements for each component based on Pure Live Seed (PLS) calculations. The specification includes common names and corresponding botanical names for accuracy in seed procurement and planting operations. Key native species in the mix include Common Milkweed (4.35%), Swamp Milkweed (2.43%), Little Bluestem (1.66%), and various flowering plants such as Purple Coneflower, Lance-Leaved Coreopsis, and Blackeyed Susan, each contributing less than one percent of the mix. Oats serve as a nurse crop, comprising 77.68% of the total mix at 20 pounds net weight, with the complete one-acre mix totaling 25.75 pounds.

The specification establishes precise measurement requirements for seed delivery and installation, with all wildflower species measured in PLS (Pure Live Seed) units to account for seed viability, while oats are measured in net weight. This standardized mix is designed to support pollinator habitat and ecological restoration objectives across Kentucky's statewide program. The attachment provides vendors with exact specifications necessary for seed sourcing, blending, and quality control to ensure consistent, high-quality pollinator plantings across multiple project sites.
