The Western Sword Fern is a magnificent, robust evergreen fern that serves as a cornerstone of the Pacific Northwest forest understory. This iconic native plant forms a large, symmetrical clump of upright to gracefully arching, leathery, dark green fronds that can reach impressive lengths. Its lance-shaped fronds are composed of numerous, single-divided, sword-shaped leaflets (pinnae) arranged in a classic fishbone pattern, each with a small, ear-like lobe at the base. A tough, adaptable, and long-lived fern, it is an outstanding choice for adding bold texture, lush greenery, and year-round structure to shaded borders, woodland gardens, and native plant landscapes.

Knowing how we measure the size?

When browsing our plants, you may notice size terms such as Gallon, Multi, or Stand. These describe how a plant is grown, containerized, or structured at the time of sale — not just its height. Understanding these terms will help you choose the right plant for your space and expectations.

🌱 Gallon Size (Container Size)

Gallon refers to the size of the nursery container the plant is currently growing in (e.g. 1 Gallon, 5 Gallon, 15 Gallon).

A larger gallon size generally means:
- A more established root system
- A sturdier plant
- Faster visual impact after planting
Example:
- 5 Gallon: Ideal for residential gardens, easy to handle, good balance of value and maturity
- 15 Gallon: More mature, provides quicker results in the landscape

Note: Gallon size does not guarantee a specific height, as growth varies by species.

🌳 Multi (Multi-Trunk / Multi-Branch Form)

Multi indicates the plant has multiple trunks or main stems growing from the base.

Commonly used for:
- Ornamental trees
- Feature plants
- Japanese maples, olives, crepe myrtles, etc.
Why choose Multi:
- Fuller, more sculptural appearance
- Strong visual presence even at younger ages
- Popular for design-focused landscapes

🌲 Stand (Single-Trunk / Standard Form)

Stand (short for Standard) refers to a single, dominant trunk with a raised or naturally formed canopy.

Commonly used for:
- Shade trees
- Street trees
- Orchard and structural plantings
Why choose Stand:
- Clean, classic tree form
- Easier clearance for walkways and lawns
- Preferred for long-term structure and uniformity

🌿 Choosing the Right Size

If you want instant impact → larger Gallon, Multi form
If you want long-term structure → Stand form
If you want flexibility and value → mid-size Gallon containers

If you’re unsure which size or form fits your project, our team is happy to help you select the best option based on your space, timeline, and design goals.

Q: How does the Western Sword Fern differ from the Boston Fern?
A: They are very different ferns. 1) Hardiness: Western Sword Fern is a hardy, temperate plant (USDA zones 5-9), while Boston Fern is a tropical plant (zones 10-11). 2) Form: Western Sword Fern has upright to arching, very sturdy, leathery fronds; Boston Fern has soft, completely arching, more delicate fronds. 3) Leaflets: Western Sword Fern leaflets have a distinctive, small, ear-like lobe at the base; Boston Fern leaflets do not.

Q: How much sun can it tolerate?
A: Western Sword Fern is best grown in partial to full shade. It thrives in the dappled light of a woodland . Along the immediate coast, it may tolerate more sun, but it must be protected from hot afternoon sun, which will scorch its fronds. Inland, it requires significant shade.

Q: How much water does it need?
A: During its first year, water regularly to establish a deep root system. Once established, it is quite drought-tolerant for a fern . In its native range, it often survives on winter rainfall alone. In hotter, drier inland areas, occasional deep watering during extended dry periods will keep it looking its best.

Q: How do I care for it?
A: Plant it in a shady location with well-drained, organically rich soil. Water regularly during its first year. After establishment, water during prolonged dry spells. No fertilizer is typically needed. In late winter or early spring, you can cut back any old, tattered fronds to make way for the fresh new growth, though this is not strictly necessary.

Q: Is it deer resistant?
A: Yes, the Western Sword Fern is highly resistant to deer . The tough, leathery texture of its fronds makes it unpalatable to deer, which is one of the reasons it is such a valuable and reliable plant in gardens with high deer pressure.

Q: Can it be grown in a container?
A: Yes, it can be grown in a large container for a number of years . Use a pot with good drainage and a well-draining, organically rich potting mix. Keep the soil consistently moist but not waterlogged. Container plants will need more frequent watering than those in the ground and may benefit from winter protection in colder zones.
