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.

Yucca rostrata 'Sapphire Skies' is a spectacular, evergreen succulent prized for its nearly perfect spherical crown of intensely powdery blue, needle-like leaves and its striking architectural form. This superior selection of the Beaked Yucca features a dense, symmetrical rosette of stiff, narrow, sharp-tipped leaves in an unforgettable sapphire-blue to silver-blue hue, creating a dramatic, sculptural focal point in any sunny landscape. In late spring to midsummer, mature plants send up tall, branching flower spikes bearing large, pendulous, bell-shaped, creamy-white flowers that attract pollinators. Exceptionally drought, heat, cold, salt, and deer tolerant, it is an outstanding choice for xeriscape gardens, rock gardens, coastal plantings, modern landscapes, and large containers.

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 is 'Sapphire Skies' different from the species Yucca rostrata?
A: 'Sapphire Skies' has shorter, more intensely blue leaves and a more compact, perfectly rounded, symmetrical crown. Its unmatched blue color is its standout feature.

Q: How large does it get?
A: The crown typically reaches 4-5 feet in height and 2-3 feet in width, though it can spread up to 4-5 feet wide over time. The flower stalks add additional height.

Q: Is it cold hardy?
A: Yes, it is reliably hardy in USDA zones 5-11, tolerating cold winter temperatures down to -10°F to -20°F (-23 to -29°C) once established.

Q: Does it need a lot of water?
A: Once established, it is exceptionally drought tolerant. Water regularly during its first year, then little to no supplemental water is needed. It thrives in well-drained soils.

Q: How much sun does it need for the best blue color?
A: For the most intense sapphire-blue coloration, plant in full sun (at least 6 hours of direct sunlight daily). In partial shade, the blue color will be less vibrant.

Q: Does it have sharp tips?
A: Yes, the leaves are stiff, narrow, and have sharp, pointed tips (needle-like). Use caution when planting near walkways or high-traffic areas.
