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

Skylark California Lilac is a tidy, compact shrub known for its deep blue flower clusters and dense, rounded form. It blooms heavily in spring, attracting a buzz of pollinators. Its manageable size, neat habit, and reliable performance make it an excellent choice for smaller gardens, mixed borders, or as a low, informal hedge. It is more adaptable to garden conditions and occasional summer water than some species.

Deep Blue Spring Blooms: Produces an abundance of rich blue flower clusters.
Compact & Dense Habit: Forms a very neat, rounded mound, typically 3-4 feet tall and wide.
Garden-Adaptable: Tolerates a wider range of soils and occasional summer irrigation better than many wild species.
Attracts Pollinators: A magnet for bees and butterflies in spring.
Low Maintenance Hedge: Can be used for a low, flowering hedge with minimal pruning.

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: Can it handle clay soil?
A: It prefers good drainage but is more tolerant of heavier soils than many other ceanothus, especially if planted on a mound or slope to improve drainage. Avoid wet, soggy conditions.

Q: How often should it be watered?
A: Water deeply to establish, then infrequently. It is drought tolerant but can handle occasional deep summer watering (once a month or less) in well-drained soil, which many hybrid cultivars like 'Skylark' tolerate better than species.
