Sambucus

life science Maturity 5-7 Next article →

The genus *Sambucus* includes between 20 and 30 different species of flowering plants. These plants are commonly known as elders. People often refer to their flowers as elderflower and their fruit as elderberry.

Members of this genus are mostly fast-growing shrubs or small trees. Some species can grow quite tall, while others are herbaceous plants. Their leaves are arranged oppositely on the stem. These leaves are pinnate, meaning they have 5 to 9 leaflets, though some species have 3 or 11. The edges of these leaflets are serrated, which means they have jagged, saw-like margins.

Understanding how *Sambucus* grows requires looking at its specific needs. These plants are nitrogen-tolerant, meaning they can thrive in areas with organic waste. They do not require a specific soil type or pH level to grow. As long as they have sufficient sunlight, they can grow virtually anywhere. Because they grow profusely and can be bent into shape, they are often used in Britain as an "instant hedge."

Most species live in temperate to subtropical regions. While they are widespread in the Northern Hemisphere, they are also found in parts of Australasia and South America.

The biology of the elder involves a specific flowering and fruiting cycle. In late spring or early summer, the plants produce large clusters of small white or cream-colored flowers. These flowers are often strongly scented. Following the flowers, the plant produces clusters of small berries. These berries start out green when they are immature. As they ripen, they turn black, blue-black, or red. In rare cases, some berries may even be yellow or white.

Taxonomy is the science of naming and classifying living things. The genus *Sambucus* was originally described by the botanist Carl Linnaeus. The name itself comes from an Ancient Greek word for a wind instrument. This refers to the practice of removing the pith from twigs to make whistles. Scientists once placed elders in the honeysuckle family, Caprifoliaceae. However, they were reclassified into the Adoxaceae family. This change happened after researchers performed genetic and morphological comparisons to the genus *Adoxa*.

The ecology of *Sambucus* involves many different animals. The berries serve as a food source for various birds and mammals. For example, migrating band-tailed pigeons eat elderberries in Northern California. The plants also support many species of Lepidoptera, which are moths and butterflies. Larvae of the emperor moth and the swallow-tailed moth use the plant as food.

In Europe, tiny insects called flower thrips visit the scented flowers. These insects help move pollen between different flower clusters. Additionally, the valley elderberry longhorn beetle is often found near red or blue elderberry bushes. The females of this species lay their eggs on the plant's bark.

Humans have used elders for food, color, and medicine for centuries. The cooked pulp and skin of most species are edible. Raw elderberries are composed of 80% water and 18% carbohydrates. They are a rich source of vitamin C, providing 43% of the Daily Value. They also contain 18% of the Daily Value for vitamin B6 and 12% for iron. The fruit is rich in anthocyanidins, which are pigments that create an intense blue-purple juice.

This juice is used as a natural colorant in food products in both the US and Japan.

Safety is a very important part of using *Sambucus*. Some species produce cyanogenic glycosides, which are compounds that can be toxic. If someone eats enough of these compounds through juice, tea, or raw fruit, they may experience nausea, vomiting, or diarrhea. For instance, in August 1983, 25 people in California became ill after eating juice made from fresh *Sambucus mexicana*. However, some species like *Sambucus nigra* and *Sambucus canadensis* do not contain these toxins in their berries or leaves. Always ensure berries are cooked to avoid potential illness.

Beyond food, the elder has many historical and cultural connections. In the past, people hollowed out twigs to use as blowguns, syringes, or flutes. The pith of the wood was even used by watchmakers to clean tools. Folklore also surrounds the plant. Some traditions suggest the tree can protect against witches. Others tell stories of a spirit called the Elder Mother who might take revenge if the tree is cut down. In modern culture, an elder branch is famously used as a wand in the *Harry Potter* series.
