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

The Orange King Bougainvillea is a spectacular, fast-growing tropical vine celebrated for its show-stopping display of vibrant bronze-orange bracts . A vigorous hybrid, it quickly covers arbors, fences, and walls with a profusion of color from its papery, modified leaves, which surround the plant's small, inconspicuous white true flowers . Its long, arching stems are armed with sharp thorns and clothed in medium to dark green, oval to heart-shaped leaves . This sun-worshipping, drought-tolerant plant is the ultimate choice for adding a bold, lush, tropical flair to large landscapes in frost-free climates .

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 does 'Orange King' differ from other bougainvilleas?
A: 'Orange King' is distinguished by its unique bronze-orange flower color, which is rarer and particularly vibrant compared to the more common pinks and purples . It is also a notably vigorous, fast-growing hybrid (Bougainvillea × buttiana) that can quickly cover large structures .

Q: How much sun does it need to bloom so profusely?
A: Full, direct sun is absolutely essential for prolific blooming . It requires a minimum of 6 hours of direct sun daily. Too much shade results in lush green growth at the expense of its signature bronze-orange flowers .

Q: How often should I water it?
A: Less is more. Water deeply but infrequently, allowing the soil to dry out completely between waterings . It flowers best when slightly stressed by dryness. Overwatering leads to lush foliage and few flowers, and can cause root rot .

Q: Is it cold hardy?
A: It is reliably hardy outdoors only in USDA zones 10-11 (and into 9b with protection) . It is damaged by temperatures below 30-32°F and killed by hard frost. In colder zones, it must be grown in a container and moved indoors to a very bright, cool location for the winter .

Q: How should I prune it?
A: Prune immediately after a major bloom cycle to shape and control size . It blooms on new wood, so pruning encourages branching and more flowers. Wear thick gloves and long sleeves to protect yourself from the sharp thorns . Avoid heavy pruning in fall, as this removes wood that would bloom the following year.
