To pull off a composition like this, you do need to be in a temperate zone where phormium (New Zealand flax) and hardy fuschia winter over most of the time. Sorry to tease if that's not the case. But look how DJH uses the two different phormium species to electrify thess fans of foliage, then picks up the pink-edged swords with a jewel-encrusted fuschia. In the background, right, you can see the feathers of that nasty California invasive, pampas grass (Dan is unapologetic about using it in his colder climate). As for that dash of baby blue in the background, well, you're going to need to garden on a bluff with a limitless expanse of sky.
