Getting into the details:

  • Gardenia contains male (stamens) and female (carpels) reproductive organs.
  • The carpel produces the pistil, which contains ovules and the Stigma.
  • Stamens produce pollen or sperm, and pollens then transfer to the Stigma.
  • Once the pollen reaches the ovules inside of ovaries, fertilization occurs, and the ovules develop into seeds.
  • At last, the plant will produce fruit.

The role of natural agents such as birds, insects, wind, and water is crucial in pollination.

Biological agents carry out the process of pollen grains, reaching the Stigma.

Gardenia can be hand pollinated, even though they self-pollinate.

If you want to pollinate your Gardenia Plant manually, you can do so by following the four simple steps mentioned below.
