This looks like something you'd see in a place that has warm, sandy beaches and rum-filled drinks. It's called Crocosmia but is commonly known as Coppertip or Falling Stars (or Monbretia, in Britain). Crocosmia are actually grown from corms. Corms are sort of like bulbs in that you basically plant them the same way but they really aren't bulbs exactly. The discussion of the difference is, frankly, beyond the scope of this blog. Which is to say, I am not nearly expert enough on the topic and so I would suggest a Google search if you are so inclined to learn more about this particular subject.
I just think it is a beautiful flower. This is a close up so don't let the image fool you, the bloom is really only a few inches in diameter but it sure packs a wallop. It requires full sun (preferably a.m.), the foliage is swordlike, it grows to about 24 inches high and is only half hardy. So for those living in climates where the winter temperatures dip below zero degrees, you'll want to dig them up and bring them inside to a cool, dry place for the winter.
Apparently hummingbirds love crocosmia but I have yet to see one come calling. I'll continue to keep watch though.
