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.

White Knock Out® Rose redefines carefree gardening with its constant display of cheerful, weather-resistant blooms. From spring until hard frost, it is covered in clusters of single-petaled flowers that open a crisp white and mature to a soft, creamy yellow, creating a lovely two-tone effect. As part of the famous Knock Out® family, it boasts exceptional disease resistance, incredible heat and humidity tolerance, and thrives with minimal attention. Its compact, rounded habit makes it perfect for mass plantings, low hedges, or containers where non-stop color is desired.

  • Continuous White to Cream Blooms: Produces an abundance of single white flowers that age to soft yellow, flowering relentlessly from spring to frost.

  • Exceptional Disease Resistance: Highly resistant to black spot, powdery mildew, and rust, requiring no spraying.

  • Extreme Heat & Drought Tolerance: Thrives in hot, humid, and dry conditions once established, with excellent rain tolerance.

  • Compact & Low-Maintenance Habit: Forms a dense, mounded shrub (3-4 ft.) that requires little to no pruning.

  • Perfect for Landscaping: Ideal for mass plantings, low borders, or foundation plantings where easy care is essential.

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.
