Reproduction


The reproduction of the plant in cultivation can be done easily by dividing the newly appeared bulbs from the main plant. In the nature, this method is also used by the Hyacinth but the plant has also specific kind of reproduction by seeds.

The plant is pollinated by different insects such as honey bees. The flowers are very fragrant and attract the insects as rewarding them with nectar.

After flowering the ripening of the seed capsules begins. They are fleshy and spherical structures. When the capsules reach maturity, they get dried and split apart on three parts. Every part has two subdivisions and contains different quantity of seeds. The seeds are black grains with one white elaiosome
Elaiosome
Elaiosomes are fleshy structures that are attached to the seeds of many plant species. The elaiosome is rich in lipids and proteins, and may be variously shaped. Many plants have elaiosomes to attract ants, which take the seed to their nest and feed the elaiosome to their larvae...
