Like Alpine Mint For Hedge?

We're on the west coast of the Olympic Peninsula. Salty, cold dry artic winds all summer, wet moderate all winter, seldom frost and snow.

Transplanted an Alpine Mint ('Prostanthera cuneata') to a very dry front yard.

Would love to purchase a number of these (love the smell and look) and form into a hedge.

Do they get that big? If they don't, what's like them that does? Details from the knowing?

Good info from ANBG: Prostanthera cuneata. Looks like propagation is easy, so if you've a bit of time, that might be an inexpensive way on expanding your hedge.

Is 1m high enough?

 

They get wide, but stay pretty low. Our old plant is about 3'-4' wide but less than 2' tall.

 

Well, it would be nice to have a small low hedge just to give a more enclosed feel to the front yard.

We don't want a monster that would block out the whole road. Can it be trained higher, perhaps? Or is there a plant like it that goes a little higher?

I've already found out that AM can grow very well in the chosen spot.

I've found alpine mint for about $8.50 a plant on the net. Is this reasonable?
