Q.Ponytail palm
I recently purchased a home in Central Florida. In the backyard is a 6 foot tall ponytail palm. There were several plants within a foot of the base of the plant that were about 8-12″ tall and looked identical to the ponytail. Could the plants be ponytails or is it more likely a similar looking grass? Thanks in advance!
I can't say for sure from your description.
Perhaps the previous homeowner planted the pups into the soil around the plant.
