Broadleaf Four-O'Clock mirabilis 4-5' tall with 3-4' spread. Started growing in mid spring about the time I wanted to plant seeds of other 4 o'clocks. I forgot about my seeds and saw this grow very fast. Noticed what it looked like and decided to wait and see. Blooming in early autumn - September. Will have to see if it is perennial. Same color of flowers as M. multiflora.
