Life Cycle of Sun flower

Phase 1: Seedling

As with most flowers, the first phase of the sunflower’s life cycle is as a seedling. After about 3 days after the seed is planted into soil, it germinates and the case begins to split as the roots shoot out and push down further into the soil.

Phase 2: Shoot

After roughly about a week, a shoot will sprout out of the soil, reaching slowly for the sun. Shortly after the shoot appears, the leaves will begin slowly opening; the steam and leaves will continue to grow larger and wider as time continues.

Phase 3: Bud

As the seedling continues to grow, eventually, a bud will be noticeable. The bud will begin to slowly unfold as the flower head slowly opens.

Phase 4: Bloom

Finally, as the flower head opens fully, the hypnotizing beauty of the sunflower can be appreciated at its prime.

Phase 5: Wilt

After a long season of beauty and life, the flowers petals will start to wilt. Eventually the whole flower will shrivel, where the seeds will then be released and scatter into the depths of nature.

Phase 6: Regrowth

Once the sunflower seed settles in an ideal spot, the sunflower life cycle will start all over again.
