Plant combinations: Naturally looks very good with rocks. Dry flower beds,  exotic, xeric, large rock gardens, sloped and terrased gardens, in large containers. Avoid planting directly atthe path (even the leves are less spiky than other yuccas). The best combinations are with smaller-leaved, smaller, groundcovering plants, succulents and fine-leaved grasses that support the majestic and unusual look. But looks well even with larger plants.

Good companions can be Artemisia, Agastache, Catanache caerulea, Eriogonum, Eryngium, Euphorbia, Gaillardia, Gypsohilla repens, Nepeta, Lavandula, Linum lewisii, Opuntia, Phlox subulata and other creeping phloxes, Scabiosa, various Salvia, Veronica. But can be combined with many plants on the average to drought tolerant scale like Achillea, shorter Aster, Echinacea, Paeonia, bearded Iris, Perovskia, Platycodon, Sedum and medium to taller grasses (Muhlenbergia, shorter Panicum, Pennisetum, Sporobolus, Schizachyrium).
