As you visit garden centers looking for annuals and perennials for your garden, you may well encounter plants with tags like the one pictured (some are prominent, others are buried). They say the seeds that grew the plant were treated with neonicotinoids, a neuro-toxic pesticide. When seeds are coated with this pesticide, the pesticide will appear in every part of the plant-leaves, flowers pollen-making the plant deadly to insects that come to pollinate it. These tags have even been found on milkweed (grown to feed butterflies) for sale in the South at Home Depots.
Neonicotinoids are linked to bee colony collapse. Please avoid any plant treated with this neurotoxin.
