Native Plants
The bright red stems of red osier dogwood along your local creek or wet ditch are a native shrub feeding birds and pollinators, and they're easy to spot and photograph as fall color arrives.
People in Canada logged 405 sightings of red osier dogwood on iNaturalist in the past week, up from 319 the week before. It's a common native shrub with red stems that stand out against fading fall leaves and later against snow. Its rise in the rankings likely reflects seasonal color change drawing attention, though the data doesn't confirm the cause.
