Most rosemary tends to bush out. It may be prudent to install a low height wire fence of some kind to help hold in the shrub. About 3 feet of spacing would be fine.

arp is a creeping rosemary, so thqt might not be good in that area
but tuscan blue or hardy hill would do great

I didn't know that Arp was a low form. In that case, I don't want that.

Maybe mixing 2 or 3 types would be more interesting...Tuscan Blue, Anna Hulka and Miss Jessopp's possibly. I'm looking for tall ones to give some sense of privacy. We just took out a row of photinias and I feel so exposed now.

Thanks!

ksrogers: how would a wire fence keep it from spreading? Wouldn't it just grow right through it?

Not to keep it from spreading horizontally, but to help contain the branches so they are not growing over an area where you don't want vegetation. Rosemary does spread out, but not usually by its roots like a raspberry cane would. If rosemary grows tall, it usually also grows larger in diameter. Here, I use a short wire fence during peony blssoming so the stems don't snap over due to the weight of the big blossoms.

Ah, I understand...thank you.
