It’s easy to collect seed from Agapanthus plants.
As the seed pods dry they will start to release their seeds. Collect and store the papery black seeds in a paper bag in a cold place until you want to sow.
The best time for sowing is late autumn or spring. Agapanthus seeds germinate quickly in general seed compost with a light covering of sand or grit and water in well. In a cool greenhouse.
We are about to collect the seeds from Artic star here and will continue to show the process of dealing with the seelings through to the flowering plant.
It is important to note that the plants that grow from the seeds will not be identical to the parent. They will have genetical variations and you may get surprising results but you’ll have to wait around 3 years before you see a flower.
