A WORD ABOUT  PESTICIDES ON MILKWEEDS

Grown as a larval plant for the Monarch, Queen and Soldier Butterfly , our butterfly plants are grown here on site from seed, cuttings, or divisions and not treated with herbicides or pesticides. Making them available without added chemical toxins to the newly hatched caterpillars as a food source also puts them on the menu for other critters like Milkweed bugs and Aphids. In reality, you can't have one without the other. Treating them in any way for the removal of the aphids etc. would also harm caterpillars as well as remove or kill the unhatched eggs laid on the plants by visiting Butterflies. We like to leave them be and allow natures system of checks and balances to kick in to control pest populations.  See Pesticides on Butterfly Plants for more information
