Phenology
If you spot tall spikes of magenta flowers along a trail or in a recently cleared area right now, you're likely looking at fireweed in peak bloom, one of the easiest wildflowers to identify and track through the season.
Fireweed is a tall wildflower with bright pink-purple flower spikes that loves disturbed ground like burn sites, roadsides, and clearings. Right now hundreds of people are logging fireweed sightings on iNaturalist, which usually means it's hitting peak bloom across a wide area. It's a great plant for beginner naturalists because the flower spikes are unmistakable and the timing lines up with midsummer walks.
