Sexual Reproduction

Aldrovanda plants require a pH of about 6, a temperature at about 77°F (25°C) and several hours of direct sunlight per day to flower and set seed.

We have hand pollinated the flowers and viable seed was produced. Their ability to self-pollinate in culture is unknown. Since it is rare for these plants to flower for us, we decided not to take any chances and hand-pollinated them. Based on our experience, light and dormancy seem to be the critical factors in promoting flowering once the correct environment has been established as indicated by vigorous growth and large plump terminal buds. The plants that have flowered for us are those grown in sufficient light and which have had a dormant period of near freezing temperatures.
