Growing Notes

While grevilleas have a naturally shrubby appearance, these larger ones can easily be pruned up into a tidy small tree by removing lower branches and suckers. They can be pruned with hedgers to make a solid wall or with pruners to create an open screen. Begin pruning early if a smaller overall plant is desirable, but don't prune more than the last two years' growth, or the plant may not bud back from where it's pruned. Remove spent flower spikes.

Special Interest

Excellent cut flowers also attract hummingbirds.
