Name: Jeanie Minnesota (Zone 4a) Replace your lawn with a garden!
I am not sure how "sports" work...I split the plant into two pieces. Before splitting it all looked exactly the same. After replanting, one piece got less sun than the other, though not a drastic difference. The flowers look different through the season as well. Some might be lighter, some darker, etc.

Old gardeners never die. They are just pruned and repotted.
