Native Plants

If you've got a damp, part-shady spot near a stream, pond edge, or rain garden, this tall red wildflower is blooming now and hummingbirds are already tracking it down.

Cardinal flower is a tall native plant with brilliant red flower spikes that bloom in late summer, and right now it's one of the most-photographed plants on iNaturalist. Nearly 800 people logged verified sightings this week, which usually means the plant has hit its peak bloom across a wide swath of its range. It's a favorite of hummingbirds and a good sign for anyone looking to add native color to a wet or partly shaded corner of their yard.
