My grandma always had a large 4 o'clock at her front door. When I was little, I thought it was the coolest plant because the flower blooms opened after 4 and closed again in the morning. It was also one of the most fragrant plants. I remember it would grow like a weed and we would always be cutting it back.
Recently, a co-worker dug up some of their 4 o'clocks and shared them with the office. I put four by my back porch. They're amazingly hardy and have taken to their spot. And, they've already started blooming! I'm really excited to have these plants. They remind me so much of my grandma.
