Yep, I agree... sage, oregano, and Thai or cinnamon basil... not 'Siam Queen' which has different flowers (big heads of blooms, just lovely), but some of the other Thai varieties have pretty flower spikes like that.
The sage and oregano are perennials, so when they start outgrowing that pot, put them in the ground so you can continue to enjoy them. And don't believe people who say not to water herbs... they are pretty drought tolerant, but they'll grow a lot better with regular water (especially in a container with well-draining potting mix), and basil really isn't drought tolerant at all.
And use them... pinch, pinch, pinch! Butter in a skillet over medium-high heat, throw in a bunch of sage leaves and fry them until they're toasty brown and crisp... butter is now heavenly flavored also and fantastic on linquini or noodles as a side dish.
