toss the seed pod, it will not come true and look like the others.
Dig up the plants after it cools off.
It is self explanatory really, once you dig them you will need to wash off some of the dirt and you can see the separate fans. Just pull them apart, replant at the same depth they were and give away your extras. Divide them every 3-5 yrs or so.
They may bloom again later in the year (not if you dig them up though). But they will not bloom anymore on the same stalks that just finished blooming. Cut those off.
