Alternative to Box

Euonymus does seem to take very easily from cuttings. But not as easily as Lonicera nitida. I read that Margery Fish made a hedge by clipping some and sticking the clippings in the ground in a row! I tried a few in a pot, all took very quickly.

 

I grew one of my front hedges from L. B's Gold cuttings. It's been in 2 or 3 years maybe, and is around 3 feet tall, but the cuttings are very very easy. I have a few more which I'm growing on to slot into a small section that I didn't quite fill. I grow a bright green L. pileata one too, [can't remember the name] which is also easy, and very versatile, although it's more of a spreading type than B's G. I epxect it would be easy enough to keep tight and small though.
We don't have the Box problems here, so there's still quite a lot of box in gardens, but lonicera nitida makes a very good small hedge. I'd say Yew would be ideal too, although the look is very different. You can even use common old privet, although it's not as evergreen as those two. Some of the ordinary Euonymou fortuneis can work as a small hedge, although not as neat if you want a formal appearance.
Pittosporums aren't reliably hardy here, so - as always- location and climate are the things to check before choosing any hedging plant.
