Beyond Sword Fern: Five Underused Northwest Natives for Shade

Sword fern earns its reputation. It is evergreen, tough, and looks good in every season, which is why it ends up in nearly every shade planting in the Northwest. But a garden of nothing but sword fern and salal is a missed opportunity. Our forests hold a deep bench of shade-loving plants, many of them quietly beautiful and surprisingly easy to grow once you understand the conditions they came from.

Start with inside-out flower, Vancouveria hexandra. Its name comes from the way the white petals fold back toward the stem, giving each small bloom the look of a turned-out umbrella. It spreads by rhizome into a soft, light green groundcover that weaves between ferns and trillium without smothering them. Give it humus-rich soil and dappled shade, and it will reward you with months of delicate bloom in late spring.

Groundcovers That Earn Their Keep

Vanilla leaf, Achlys triphylla, is another spreader, but a gentler one. Its single three-lobed leaf sits atop a slender stem, and in midsummer it sends up a spike of tiny white flowers that smell faintly, and genuinely, of vanilla. It goes dormant by late summer, which is not a flaw but a rhythm. Pair it with evergreen plants that hold the space while it sleeps. Deer tend to leave it alone, which is more than can be said for many woodland plants.

For something with a bit more presence, consider redwood sorrel, Oxalis oregana. It carpets the ground under conifers on the coast and tolerates deep shade better than almost anything else in our flora. The clover-like leaves fold down in bright sun and reopen in the evening, a small daily performance. It spreads enthusiastically, so give it room or a boundary. The pale pink flowers in spring are a bonus, not the main event.

Structure and Surprise

Fringecup, Tellima grandiflora, brings vertical interest to the shade garden. Its scalloped, hairy leaves form a low rosette, and in spring it sends up tall wands of fringed, greenish-white flowers that age to a soft red. It self-sows politely and looks wonderful massed along a path or at the edge of a woodland border. Hummingbirds work the flowers, and the foliage stays tidy well into autumn.

Finally, there is inside-out flower's quieter cousin, the wild ginger, Asarum caudatum. Its heart-shaped leaves are glossy and handsome all season, and the unusual maroon flowers sit hidden beneath the foliage, pollinated by ground beetles. It wants moisture and shade and will slowly form a dense, weed-suppressing mat. Grow it where you can kneel down and look under the leaves, because the flowers are the secret worth finding. Together, these five plants can turn a dark, forgotten corner into the most interesting part of the garden.
