Answer: In terms of plant growth, 6-12 inches a year is relatively fast. The only way to get a hedge faster is to purchase larger plants. Choose 5 or 10 gallon sizes and you'll have an almost immediate privacy hedge. Pink Princess is a nice hedging plant; sweetbroom grows slower than escallonia. Or, you might consider:
Cherry Laurel (Prunus caroliniana) grows 25-30 ft. high x 18-20 ft. wide-easy -fast growing evergreen with long clusters of small white flowers in early spring. It makes excellent tall, narrow hedge and may be pruned severely.
Pittosporum Pittosporum tobira grows 10-12 ft. x 15-18 ft. -easy culture; fast growing evergreen with fragrant, cream white flowers in late spring. There's also a variegated green/white variety.
Redleaf Photinia Photinia glabra 12-15 ft. x 9 ft. -must have sun -medium-fast growing evergreen with white flower clusters in March-April and bright red-wine new growth when pruned.
Good luck with your landscape!
