This variety of hydrangea showcases pointed, oval leaves that carry a deep green hue, creating a rich backdrop for the plant's standout feature: its flowers.

- Toxicity
To humans
The common name for Hydrangea serrata 'Santiago' is mountain hydrangea. Mountain hydrangeas contain a compound called hydrangin, which can be toxic if ingested. However, poisoning from hydrangeas is rare. If large quantities of the plant, particularly the leaves and flowers, are consumed, they may cause gastrointestinal upset, with symptoms such as nausea, vomiting, and diarrhea. In more severe cases, ingestion can lead to depression, lethargy, and confusion. It is advisable to keep any part of this plant out of the reach of children to prevent accidental ingestion.
To pets
Mountain hydrangea can be toxic to pets if ingested. The plant contains compounds such as cyanogenic glycosides, which can release cyanide when chewed or digested. Symptoms of toxicity in pets may include vomiting, diarrhea, depression, and in severe cases, could potentially lead to more serious symptoms such as difficulty breathing or seizures. As pets, particularly dogs and cats, can be more likely to chew on plants, it's important for pet owners to ensure these plants are kept out of reach to prevent accidental poisoning.

Prune the Mountain Hydrangea after it blooms to remove spent flowers and encourage new growth. Light pruning can be done to shape the plant in late winter or early spring before new growth begins. It is generally recommended to remove no more than one-third of the plant to maintain its health and fullness.

- Life cycle
Hydrangea serrata 'Santiago', commonly known as Bluebird Lacecap Hydrangea, begins its life cycle as a dormant seed that requires stratification before germination. After stratification, the seed germinates in spring, developing into a seedling with a basic root system and foliage. As the plant matures, it enters a vegetative stage, producing larger leaves, stems, and a more extensive root network. Once it reaches maturity, typically within a few years, it enters the reproductive stage, producing distinctive lacecap flowers with both small fertile florets and larger sterile florets which can be blue, pink, or purple depending on soil pH. After pollination and fertilization, the plant produces seed capsules that, upon maturation, release seeds to complete the cycle. Bluebird Lacecap Hydrangea enters a period of dormancy during the colder months, conserving energy to begin the cycle anew in the following spring.
- Propogation
Propogation time
Spring to Summer
The most popular method of propagating Hydrangea serrata 'Santiago', often referred to as Mountain Hydrangea, is through softwood cuttings. This process typically takes place in late spring to early summer when the plant's new growth is still tender and green. Cuttings should be about 5 to 6 inches long with several sets of leaves. The lower leaves are removed and the cut end is dipped in rooting hormone to encourage root development. These prepared cuttings are then inserted into a moist potting mix and placed in a well-lit area with high humidity, but out of direct sunlight. Ensuring the medium stays consistently moist but not waterlogged is crucial for the successful rooting, which may take several weeks to occur. After roots have developed, cuttings can be transplanted into individual pots to grow on before being planted out into their final location.
