Campanula portenschlagiana (syn. Campanula muralis) is a vigorous, mat-forming evergreen perennial prized for its profusion of star-shaped, violet-blue flowers and its ability to thrive in rock walls, crevices, and dry, well-drained soils. This tough, low-growing plant forms a dense, spreading carpet of small, rounded to kidney-shaped, glossy, dark green leaves. From late spring through summer, it is covered with an abundance of upward-facing, star-shaped, bright violet-blue flowers (to 1 inch across), creating a spectacular, long-lasting display that attracts bees, butterflies, and other pollinators. Exceptionally adaptable, drought-tolerant once established, and able to cascade beautifully over walls, it is an outstanding choice for rock gardens, stone walls, slopes, borders, containers, and as a colorful ground cover in sunny to partially shaded areas.

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.
