Do you know what this is and what to do with it?

Loads of questions... We have bought a house with a well planted garden and we know nothing about gardening, I have a gardener coming in 3 weeks but I'm worried about this now. This plant is losing its flowers, and collapsing under it's own weight. Should I cut it back, if so how? Will it come back next year? What is it? I don't think its
Lavender because it doesn't smell, but I appreciate it does look like lavender.
Thank you in advance!

It looks like Linaria purpurea, toadflax. Perennial but can get woody and ugly at the base - you should get seedlings popping up to replace it. Cut it back, it should regrow and possibly flower again. Bees love the flowers!

Thank you so much. I'll cut it back. The bees do indeed love it. We have loads of herbs and lavender too so we have bees everywhere. :)

Yes, purple toadflax. It self-seeds and sometimes you get the occasional pink one appear as well.

They do regrow, but are fairly short-live perennials, so maybe a 2-3 years, but by then it will have self-seeded to replace itself anyway. We have lots of it, and I just let it grow wherever it wants, and dig up ones in the wrong place if there are too many.
