I have a stand of lovage in my garden and like everyone says once it's established it just keeps coming back.
Mine grows in a shady corner where not much else will grow & it is very happy, just poking it's head above the ground right now.
I dry it and use it over the winter, in all the stocks I make, instead of celery.
Oh & I grew it from seed, before I knew much about that sort of thing & I didn't manage to kill it
