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.

Imperial Blue Cape Plumbago is a stunning and versatile evergreen shrub that provides an exceptionally long season of clear, sky-blue flowers. From spring through fall, it produces continuous, rounded clusters of delicate, phlox-like blooms that seem to float above the mound of light green foliage. Its long, pliable stems allow it to be easily trained as a sprawling ground cover, a graceful cascade over walls, or a charming climber on a trellis or fence. Heat-loving, drought-tolerant, and trouble-free, it is a must-have for adding soft, cool color to sunny gardens.

  • Prolific Sky-Blue Blooms: Flowers non-stop from spring until frost with abundant clusters of pure, clear sky-blue flowers, attracting butterflies.

  • Versatile, Mounding & Trailing Habit: Naturally forms a loose, spreading shrub (4-6 ft. tall, 6-8 ft. wide) with long, arching stems perfect for training or allowing to spill.

  • Excellent for Training & Topiary: Its flexible stems can be easily tied to supports to create flowering walls, pillars ("standards"), or cascading waterfalls of bloom.

  • Heat & Drought Tolerant: Thrives in full, hot sun and requires minimal water once established. Highly resistant to pests and diseases.

  • Low Maintenance & Fast-Growing: Requires only occasional pruning to shape and encourage more blooms. Blooms on new growth.

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 do I train it into a standard (tree form)?A: Select one strong, central stem and stake it upright. Remove all other basal shoots and any side branches from the lower portion of the main stem as it grows. Once it reaches the desired height, pinch the tip to encourage branching at the top, creating a rounded "canopy" of flowers.
