I thought I would go out and look for some example of the different ways plants increase.
These are anywhere from a few inches to a foot or more away from the mother plant. I think they can spread out as far as two or three feet away.
In this photo you can see the small fans forming a line of plants from the mother plant.
This new fan is in between two name cultivars, so I'll have to wait for it to bloom to see if it belongs to either of them. It could have come up from the remains of a previous plant.
I think this is an example of a scape coming up between two fans that will eventually split.
This looks like an example of fans developing right next to the mother plant.
Here is Prairie Blue Eyes: Known for its fast increase:, There must be between 30-50 fans in this small clump. It was a few fans planted from Wild's on March 19th, 2015.
