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.

Wrinkled Blue Kohuhu offers a uniquely cool and textured look with its distinctive silvery-blue, crinkled foliage. The small leaves have a wavy, “wrinkled” surface and a stunning frosted blue-gray hue that provides exceptional contrast against typical green shrubs. Its narrow, upright, and fast-growing habit makes it an outstanding choice for creating a tall, architectural screen or columnar accent with extraordinary color and texture, all while bearing the species' fragrant spring flowers.

Unique Silvery-Blue Foliage: Features small, wavy-edged leaves with a distinctive wrinkled texture and a powdery, silver-blue color.
Narrow, Fastigiate Habit: Grows in a notably upright, columnar form, reaching 10-12 feet tall but only 4-6 feet wide.
Exceptional Textural Interest: The combination of color and leaf texture provides unmatched visual and tactile interest in the landscape.
Fast-Growing Architectural Screen: Ideal for creating a quick, tall, and narrow privacy screen or a striking vertical element.
Cool Color Contrast: Its cool-toned foliage acts as a perfect foil for green plants and makes warm-colored flowers pop.

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: Does the blue color fade in hot sun?
A: The silver-blue color is quite durable. It holds up well in full sun to partial shade. In fact, full sun often enhances the silvery, frosted appearance of the foliage.

Q: Can it be kept narrower than 4-6 feet?
A: Yes, due to its upright growth habit, it can be lightly trimmed on the sides to maintain an even narrower profile (e.g., 3 feet wide) for an ultra-formal columnar look.
