well a weed is a plant in the wrong place . wildlife garden means plants that our native insects and wildlife enjoy and that benefit them . realy if you like it keep it and if you dont like it well id pull or dig it up realy or if you like it keep it . the other factors are will it take over or grow everywear ? do you actualy like it yourself ? do the insects like it ? does it flower ? the list goes on realy . realy firstly sorry i dont know what it is sorry but at the end of the day its your garden and your desishion excuse my spelling . i would find out more just incase it spreads and takes over myself and for peace of mind .

It looks like Tarragon. If it is then you can use it in cooking. Nice chopped finely in Tuna mayonnaise!

....but smell it first if you are familiar with the smell of Tarragon.

sounds usefull .

Np..This can grow & grow, there is no stopping it once it starts, at first i
let it have its own freewill, thought it may flower, but alas, no flowers..
So i did cut it down, but it has come up again this year, twice as strong..
`I am begining to think it may be Jack`s Beanstalk..LOL I have `Nepeta, that
is close by, so cannot tell if bees & Butterfly`s like it, they are swarmed around `Nepeta...oh! well i do not suppose it can do any harm, after all
like you said, its natural, so it probably belongs there...Thanks for your response...:~ )) By the way `How is your little family coming along? Did you
decide to keep any?

Fractal, i will go & have a sniff tomorrow, would be lovely, if it is Tarragon,
but, i do not think Tarragon grows as tall as this 1..thank you, fractal for your comment..

well if your not happy with it tarragon or not id dig it out as apposed to cutting it down .good luck im sure youl make the right decission .
i found homes for all my puppies but im going to breed her one more time with a chocolate sharpei in a year then ill keep one i think . ill get her spayed after that . anything could happen between now and then so we will just have to see . take care bye for now xx.

How tall is it Freesiaperson?

i dont know what you mean fractel . do you mean the hight of an eskimo ? is it a joke ? you got me .

It had grown to about 10ft before i cut it down, the last time..
So, it could grow even taller, a bit like bamboo, could even become evasive
if left.. i do hate cutting anything down..Oh! by the way Fractal i cannot smell
anything at the moment as, i have a stinking cold, plenty of tissues on
stand by..LOL

Hmmmm, it won't be Tarragon then at 10ft !!!

It still looks like it might be some type of Artemesia though. I'm intrigued.
