Bay Area–Based Nursery

We specialize in plants grown and delivered in their original pots and soil.
Because of their size and weight, our plants are not suitable for long-distance shipping and are delivered locally to ensure health and quality.

While delivery is limited to our local service area, we’re happy to support garden design and plant selection remotely.

For local plant professionals, we’re always glad to connect and explore ways to support your customers.

Astelia 'Silver Shadow' is a striking, evergreen perennial prized for its bold, arching, metallic silvery-green to pewter foliage and architectural, clumping form. This New Zealand native forms a dramatic, sword-like rosette of broad, strappy leaves with shimmering, silvery undersides that catch the light and provide year-round interest. Small, inconspicuous, yellowish-white flowers may appear on branched spikes within the foliage in spring on female plants, but the plant is grown primarily for its stunning foliage. Exceptionally drought-tolerant once established (though occasional summer irrigation improves appearance), tolerant of coastal conditions, and low-maintenance, it is an outstanding choice for modern landscapes, xeriscape gardens, coastal plantings, rock gardens, containers, and as a striking accent specimen.

Knowing how we measure the size?

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.

FAQs

Q: How large does Silver Shadow Shore Astelia get?
A: It forms an architectural clump, typically reaching 2-3 feet in height and 3-4 feet in spread.

Q: Is it drought tolerant?
A: Yes, it is quite drought tolerant once established and can survive months without water in California gardens. However, occasional summer irrigation improves its appearance and keeps foliage lush.

Q: How much sun does it need for the best foliage color?
A: It performs best in partial sun to light shade, where the metallic silver-green foliage is most striking. In full sun, the leaves may scorch, especially in hotter inland climates.

Q: Is it cold hardy?
A: It is reliably hardy to 20-25°F (-6 to -4°C), suitable for USDA zones 8-10. It requires protection from hard freezes.

Q: Is it tolerant of coastal conditions?
A: Yes, due to its New Zealand ancestry, it is highly tolerant of coastal conditions, including salt spray and wind.
