I love flowers so much, I can never pick just one favorite. I love peonies, tulips, lily of the valley, and poppies the best.
When I moved to this house the previous owners had planted day lilies, daffodils, iris, orange poppies and roses that still bloom. I have added tulips, peonies, hollyhocks, and pink poppies. I have also added some other blooming perennials that I don't remember the names of... I stick mostly to perennials now. In the past I have planted some annuals in the spring - petunias, impatiens, and begonias - maybe I will do some more this year. My yard has really gotten away from me the past two years because we weren't living here while our house was being renovated, so I have some work to do to get it to where it was before we moved.
