The flowers are beautiful and colorful and they always entice the hummingbirds! They even pass up other hummingbird-attracting flowers for these flowers! I love this plant and its flowers!

I've a double-stacked tomato cage for the hummingbirds to sit and rest. They love to perch, look around, and guard their flowers!

Porterweed, its common name, is easy to grow and love! Wish it was available locally.

The one tiny leaf is missing, and I think it may have croaked. I'll leave it there, just in case it resurrects itself.
