I've searched some sites and found this shrub to be 3 to 6 ft approx ht and width. Average seems about 5x5 ft. So I would say plant about 4 to 5 ft apart. If you are in Hammond (I am from St. Bernard), yours will likely be on the large size of the continuum.

A bit off topic, but what are good holly choices for South La.? I'm trying to plant a privacy hedge & have seen some very healthy hollies growing in the Lafayette area but don't know the varieties.The nicest ones are at the Carmelite convent on the Breaux Bridge Hwy.
I picked up some little yaupons @ WalMart but would like the large leaf hollies,too.Thanks!
