FAQ
How does this compare to a standard CP42?
A standard CP42 runs 30–45 species. Leopold runs 70+. You get more bloom windows, more specialist-pollinator support, and a more resilient stand — at a higher seed cost.
Does this qualify as a monarch mix?
In years when milkweed supply is tight, this mix still meets CP42 pollinator requirements but may not carry the extra milkweed load required for a designated monarch mix. Confirm current milkweed content when quoting.
