They flower at this time of year, but the best time to divide and replant them is in the middle of winter, when they're dormant. Even though dormant, you still have to be careful not to let the roots dry out. It's important to either get them back in the ground immediately (as in the same day you dig them), or into soil in a pot.
I've divided and replanted that original handful that I was given many times over. They bulk up in my garden very quickly, and so far have taken well to every bed I've planted them into. I've had great luck with them.
