So I purchased my first Agastach, and Im debating if I should plant it in a large pot or if I should plant it in my raised bed where my rosemaries are.

How agressive is this in central Texas? Does it do well in pots? Would it take over a raised bed? Im assuming I will have to divide it in fall or spring after the first year, true?

Im kinda excited about what this plant can do for my landscaping. Surprised I havent tried this plant before.
