Pippi - there are a few native varieties of the ageratum. The common native to the east is the blue mistflower - conoclineum colestineum. It used to be in the eupatorium family but those crazy taxonomists changed it a few years ago. It spreads easily and can take over a good sized area. Transplants easily. Mine bloomed and are spent.

A friend from Texas sent me the "west Texas mistflower" last year. The foliage and growth habit are very different. It continues to bloom, and I still have monarchs hanging out on it. I didn't want the plants to cross pollinate so I planted them pretty far apart. W. TX is not exactly a native here in NC, but she's doing very well!

These are related to boneset, eupatorium, joe pye. Crazy taxonomists really did a number on this one:
