It owes its German name to the black point inside the flower, the “eye”, which used to be completely black. There are also new breeds with green, brown or even without “eye”.
If you have already grown Black-Eyed Susans in the garden, you can harvest seeds from the flowers in order to propagate them and to grow new plants yourself next spring.
How to collect the seed
If you want to collect Black-Eyed Susan seeds, don't cut off all of the withered flowers. Leave a few flowers so that seed pods can form in which the seeds will mature.
The capsules turn dark in color when the seeds are ripe. You can test the ripeness by pressing open the seed pods. Ripe seeds then pop out. They are round with an indentation and somewhat resemble small bowling balls.
To collect the seeds, either put your hand around the seed pods before cutting them, or put the pods in a plastic bag to prevent the seeds from being thrown away.
The black-eyed Susanne is sown from February
To grow new plants, the seeds are sown on the warm windowsill from February.
The germination time is up to three weeks. Then the plants are separated and the tips cut off for better branching.
Since the black-eyed Susanne is not hardy, she is only allowed to move outside at the end of May.
Tips & Tricks
The seeds of the black-eyed Susan not only germinate very slowly, they also germinate very irregularly. Experience shows that a third of the seeds do not grow. So collect and sow more seeds for more plants than you will need.
