Sister Theresa Bigleaf Hydrangea is a charming and graceful variety known for its delicate, two-toned flower heads and reliable garden performance.

Reliable Old-Wood Bloomer: Produces a generous and consistent display of its distinctive flowers in late spring to early summer from buds set the previous year.
Healthy, Robust Foliage: The plant is clothed in an abundance of large, healthy green leaves that provide a perfect backdrop for the pale flowers.
Excellent for Cutting: The unique bicolor blooms are highly desirable for creating soft, romantic fresh flower arrangements.

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

Q: Do the flowers change color with soil pH?
A: The pink portions of the florets can be influenced by soil pH, potentially becoming a slightly deeper pink in alkaline soil or a more mauve-pink in acidic soil, but the distinctive bicolor pattern remains.

Q: How should I prune it?
A: Prune with care immediately after flowering in the summer. This allows time for the plant to set new flower buds on the old wood for the following year. Avoid fall or spring pruning.
