There's a lot of buzz about the importance of pollinators to our food system and a big push for home gardeners to include more bee-friendly plants. Some of your neighbors, like mine, might be looking to get their yards officially certified as officially bug-friendly habitats. So it's time to start making lists of the plants and seeds we need, then head to the nursery, right?
Well, pause a moment in that list-making, friends, because what you may not be aware of is that some of those lovely plants at the nursery labeled as "bee friendly" might actually be harmful or even toxic to pollinators. Remember last year when a Wilsonville landscaping company sprayed dozens of blooming linden trees, killing more than 50,000 bumblebees? The insecticide they used to spray the trees—apparently without reading the instructions, which strictly forbade using it on trees in bloom and which the company was subsequently fined a bit more than $2,800, about a nickel a bee—is one that is often used on landscaping plants.
Called a neonicotinoid, or "neonic" (pron. NEE-oh-nick), it's a systemic chemical that's absorbed by the plant and dispersed through the plant tissues, including pollen and nectar. Developed to target nerve impulses in insects and other invertebrates, neonicotinoids are deemed "safe" since harm to humans and other mammals is minimal. However, neonicotinoids are toxic to bees and many other beneficial insects and can linger in the soil for months or even years, where they can be picked up by the next season’s plants.
