What will happen when my perennial salad/herbs go to seed?

[Inastate]

These two in particular.

Broad Leaved Sorrel: Planted last year in spring/summer, been doing very well and just started bolting for the first time these last few weeks.

Curry plant (Helichrysum italicum): Bought in a small pot from a garden centre last summer, after which it flowered, and was recently repotted into a larger pot with better soil. It is now looking a lot more vibrant and healthy.

The thing is, both are trying to bolt.

Does anybody know what will happen to them?

For example with the curry plant, I want it to grow nice and big so I can use it's tasty leaves on a regular basis. Will it flower then sort of die back or anything? Should I pick the young flower heads off and encourage new growth?

And what about the sorrel? I'm hoping it will just finish flowering as soon as possible as I use it a lot. What will happen after it's flowered and went to seed? Will it die back again until next year, or will I see vigorous new growth?

At what point can I start pulling the sorrel seeds off so I don't get them all over the raised beds?

Apologies about all the questions, hopefully it makes sense. I'm sure you's get the gist. I just want big healthy plants, but it's all been temporarily hindered!

I'll get some photographs tomorrow to liven things up a bit.

Thanks for any help. You lot have helped me so much, and I really appreciate it.

Sorrel is a close relative of the dock, and docks are very hard to kill unless you dig out the root. My veggie book says to cut back the flowerheads before it goes to seed. I would expect it to regrow fairly quickly, although I haven't grown it myself.

Helichrysum Italicum is in pruning group 10 according to the RHS guide https://www.rhs.org.uk/advice/profile?PID=168. You need to know whether it flowers on this year's or last year's growth.

3. Evergreen shrubs (Pruning group 10)

Timing: Prune immediately after flowering where flowering is on the previous year's growth, or in the subsequent early to mid-spring if flowering is on the current year's growth.
Examples: Bouvardia, Heather (Calluna), Erica, Helianthemum, Hyssopus, Lavandula, Ruta, Santolina, Thymus, gorse (Ulex).
Pruning: This group of evergreen shrubs flower on the previous year's growth in spring or early summer, or on the current year's growth in late summer and autumn. Remove shoots that have flowered to within 1.5-2.5cm (¾-1in) of the previous year's growth.

I'm not so technical!! I chop the sorrel off to the ground on a regular basis and it re grows fast. The curry plant gets a haircut on a regular basis to keep it bushy and I don't let it flower.
