Since I accidentally left leeks go to seed and discovered what
fantastically beautiful flowers they have, I let some do it every year.
The flower stems are 3 or 4 ft high and very strong (no staking required
even in this windy garden) The flowers have glaucous buds opening to
purple flowers, and then the handsome seedheads.

Onions and chives also.
