The Four o’clock success in the garden continued this month when I was digging around the garden and discovered the Four o’clock tubers. I went from harvesting four o’clock seeds that I couldn’t germinate, to having a successful germination rate this year and even four o'clock blooms. In a previous post a garden commented that propagating four o’clocks vegetatively was easier than growing them from seeds and the reason I searched for these tubers in the garden.
