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.

Royal Cape® Plumbago is a vibrant selection known for its richer, deeper cobalt-blue flowers. It offers the same incredible flowering performance and versatile habit as the species but with a more intense color saturation. The striking blue clusters create a bold visual impact against the light green foliage, making it an outstanding choice for adding a punch of color to sunny borders, training on a bright trellis, or using as a colorful, informal hedge. It is a reliable workhorse for warm-climate gardens.

  • Vivid Cobalt-Blue Flowers: Distinguished by its clusters of rich, deep cobalt to blue-violet flowers that provide a more dramatic color statement.

  • Continuous Warm-Season Bloom: A prolific bloomer from late spring through autumn, often flowering nearly year-round in frost-free climates.

  • Robust & Fast-Growing Shrub: Forms a dense, rounded shrub (4-6 ft. tall and wide) with long, pliable stems ideal for training or pruning into shape.

  • Heat & Sun Loving Performer: Excels in full sun and hot, dry conditions, demonstrating excellent drought tolerance once established.

  • Ideal for Color Massing & Structures: Perfect for creating a vibrant flowering hedge, covering a slope, or training up a sunny wall or pergola.

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 often should I water it?A: Water regularly to establish a deep root system in the first year. Once established, it is very drought-tolerant. Water deeply but infrequently, allowing the soil to dry out somewhat between waterings. Overwatering can reduce flowering.
