As indicated by my username, I'm super excited for my fireweed to bloom! It's a perennial that dies back every autumn and regrows in the spring (this time of year it grows so quickly!). It spreads by wind-blown seed, but also by root so my fireweed patch grows bigger and thicker every year, which is such a fun development to watch. The flowers are so pretty and the native bees go gaga over it. Once established it's basically a zero-maintenance plant (where I live it grows wild along highways). I highly recommend it for any pollinator-friendly gardener living in its wide native range that doesn't mind a little weediness (they're easy to remove if they pop up where they're not welcome).
