Flowering end: cutting yes or no?
When the flowering period is over, the ornamental onion looks poor. Its leaves have yellowed. Cut off the inflorescences if you do not want the ornamental onion to form seeds and use them to reproduce independently in the garden (self-sowing).
If you don't mind propagation, you can leave the inflorescences or seed heads. The seeds are ripe in autumn and can be collected if necessary. The seed heads continue to be decorative until winter.

You are welcome to cut off the flower stems and place them in a vase. They are well suited as cut flowers.
