An observational journal about the sunflower

The root continues to grow downwards. The single stem grows hollow and smooth, revealing large spade-shaped leaves from the growing tip. Gradually, the plant’s growing tip reveals the first hints of development of the flower bud. The plant stem becomes more woody.

About three weeks after the flower bud first becomes visible at the tip of the sunflower stem, it enlarges and begins to reveal a flattened disc. Over the course of one week, the yellow ray florets, the disc florets bloom across the core of the sunflower blossom. It is yellow, looking beautiful.
