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.

Blue Chalk Sticks is the quintessential succulent groundcover, renowned for its ability to create sweeping seas of cooling blue foliage. Its long, curved, chalky blue leaves densely pack trailing stems, forming a lush, weed-suppressing mat that requires minimal care. The thick layer of white farina on the leaves not only provides its iconic color but also protects it from sun and drought. A workhorse in the dry garden, it offers year-round visual calm, punctuated in summer by small, white daisy-like flowers. It is the go-to plant for effortless, high-impact coverage in sunny, well-drained areas.

Creates a fast-spreading, dense mat of long, curved, blue-green leaves covered in a distinctive white powdery coating.
An exceptionally effective, low-maintenance groundcover that dramatically reduces weeds and garden upkeep.
Thrives on neglect, requiring only full sun and excellent drainage, and is highly drought-tolerant.
Produces small white daisy flowers in summer, attracting pollinators.
Provides excellent erosion control on slopes and is perfectly suited for fire-wise landscaping.
Evergreen in mild climates with a prostrate, trailing growth habit ideal for large areas, rockeries, and container spilling.

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: How do I encourage it to spread more quickly as a groundcover?
A: You can promote faster coverage by planting individual stems closer together (about 12-18 inches apart). Taking stem cuttings and rooting them directly in the gaps is also a very easy and effective way to fill areas.

Q: Is it deer resistant?
A: Yes, its succulent foliage is typically not palatable to deer, making it an excellent choice for gardens in deer-prone areas.

Q: Can it handle coastal conditions?
A: It excels in coastal gardens. It is highly tolerant of sandy soil, wind, and salt spray, making it a classic choice for seaside landscapes.

Q: How does it compare to ‘Dwarf Blue Chalksticks’ for a small space?
A: For a small space or a neat border, choose the ‘Dwarf’ variety (S. serpens) for its compact, clumping form. The regular Blue Chalk Sticks (S. mandraliscae) is much more vigorous and spreading, better suited for covering large areas, slopes, or as a dramatic container spiller where it has room to trail.
