One of my favorite garden tasks is dividing perennials. It reminds me of a buy one, get one free sale. I start with one plant and wind up with 2, or more, for free!
There are other reasons for dividing perennials. Some need to be rejuvenated while others have grown too large for their garden niche.
I love native plants. I love to grow them. I love to read about them. I love to preserve them and the wildlife they nourish.
