An observational journal about the sunflower
1 June
Germination （使发芽）
Covered with 1/2 cm of moist soil, the sunflower seed takes five to 12 days to come up after being planted. Water has been added regularly and the hard seed coat softens in the damp soil to allow the first root to pierce downwards and the
first leaves to push to the soil surface.
6 July
Growth
The root continues to grow downward. 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.
26 July
Flowering
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 disk. Over the course of one week, the yellow ray florets, the disk florets bloom across the core of the sunflower blossom. It is yellow, looking beautiful.
