This hybrid was a happy discovery in Denmark—it is a powerhouse performer, growing vigorously to towering heights. There's no need to prune Green Giant, you can simply let it grow its full 30-40' for a windbreak. It does respond well to pruning, however, if you'd prefer something a little more uniform for hedging. The biggest benefit, other than its brilliant size is that the lush, abundant foliage puts the 'green' in evergreen—it won't turn yellow or bronze in winter. This variety is not very picky about soil, but it prefers well-drained if you have it.
