I usually wait until May 15th, which was my grandmother's birthday, to plant annual flowers, but this year my daughter and I put in flowers on the 6th-- she was anxious to have her own flower pot. I thought I'd post what they look like now then later after they fill in.
The spaces are planted with flower seeds. And, yes, there are two sweet potatoes in there. Last year I had one grow over six feet long. Wish them luck!
