What it is like
Sambucus pubens is a deciduous Shrub growing to 4 m (13ft 1in). See above for USDA hardiness. It is hardy to UK zone 4. It is in flower from June to July. The species is hermaphrodite (has both male and female organs) and is pollinated by Insects. Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and can grow in heavy clay soil. Suitable pH: mildly acid, neutral and basic (mildly alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers moist soil. The plant can tolerates strong winds but not maritime exposure. It can tolerate atmospheric pollution.
Height (m): 4
Where it is found
Moist to wet soils along streams, in woods and open areas from valleys to around 3,000 metres.
N. America - British Columbia to Newfoundland, south to Georgia, Iowa, Colorado and California.

How it is used
Food
Rating: 3
Fruit - raw or cooked. A bitter flavour. The fruit is quite nutritious, having a relatively high fat and protein as well as carbohydrate content. The fruit can be dried prior to use, it will then lose some of its rank taste. The fruit is about 5mm in diameter and is borne in large clusters making it easy to harvest. Some caution is advised, see the notes above on toxicity. Flowers - raw or cooked. The root is made into a tea-like beverage.
Tea: the various herb teas that can be used in place of tea, plus the genuine article.
Medicine
Rating: 1
The bark and the leaves are used as a diuretic and purgative. The blossoms have been used in the treatment of measles.
Diuretic: Acts on the kidneys, promoting the flow of urine.
Purgative: A drastic laxative causing a cleansing or watery evacuation of the bowels, usually with a griping pain.
Other
Rating: 1
The stem is easily hollowed and can be used to make a whistle.
Musical: Specific mention of plants used as musical instruments. Does not include the various woods that can be used for making musical instruments.
How it is grown
Tolerates most soils, including chalk, but prefers a moist loamy soil. Grows well in heavy clay soils. Tolerates some shade but is best in a sunny position. Tolerates atmospheric pollution and coastal situations. Closely related to S. racemosa and considered part of that species by some botanists. Plants in this genus are notably resistant to honey fungus.
Propagating it: Seed - best sown as soon as it is ripe in the autumn in a cold frame, when it should germinate in early spring. Stored seed can be sown in the spring in a cold frame but will probably germinate better if it is given 2 months warm followed by 2 months cold stratification first. Prick out the seedlings into individual pots when they are large enough to handle. If good growth is made, the young plants can be placed in their permanent positions during the early summer. Otherwise, either put them in a sheltered nursery bed, or keep them in their pots in a sheltered position and plant them out in spring of the following year. Cuttings of half-ripe wood, 7 - 10cm with a heel, July/August in a frame. Cuttings of mature wood of the current season's growth, 15 - 20cm with a heel, late autumn in a frame or a sheltered outdoor bed.

Hardiness: 4-8

Things to keep in mind
Although no specific mention has been seen for this species, the leaves and stems of some, if not all, members of this genus are poisonous. The fruit of many species (although no records have been seen for this species) has been known to cause stomach upsets to some people. Any toxin the fruit might contain is liable to be of very low toxicity and is destroyed when the fruit is cooked. NC State University have noted Cyanogenic glycoside and alkaloids can cause low toxity if eaten.
