    Sambucus caerulea 'Blue Elder'

    Caprifoliaceae: a large, deciduous shrub, which can grow to be 9m (30ft) in height. The white or creamy coloured flowers, occurring May to June, are numerous and form a flat-topped cluster usually about 5–20 cm (2–8 in) wide. The flowers have a strong, unpleasant odour. The fruits given are berry-like drupes. They are juicy, round, and approximately 4–6 mm in diameter. They are bluish-black appearing as a pale powdery blue colour. The leaves are hairless, strongly pointed and sharp-toothed. Native to the Western United States, north-western Mexico, and British Columbia. It is found from the Pacific coasts, through California and the Great Basin, to Montana, Wyoming, and Texas.

     

    USES:

    The fruit can be eaten raw, cooked or used in preserves. They have a rather sweet taste and are juicy, but they are full of small seeds, this is the best flavoured of the North American elders. The fruit can be dried for later use.

    The tree has analgesic, antiseptic, diaphoretic, febrifuge and purgative properties.

     

    GROWING INFORMATION:

    Blue Elderberry seeds have a deep dormancy within them, this requires a degree of patience to overcome and it is usually quite easy to get high levels of germination if the correct procedures are followed.

    First prepare a free draining substrate into which the seeds are to be mixed, this can be a 50/50 mixture of compost and sharp sand, or perlite, vermiculite. The chosen substrate needs to be moist (but not wet), if you can squeeze water out of it with your hand it is too wet and your seeds may drown and die. Mix the seeds into the substrate, making sure that there is enough volume of material to keep the seeds separated. Place the seed mixture into a clear plastic bag (freezer bags, especially zip-lock bags are very useful for this -provided a little gap is left in the seal for air exchange) If it is not a zip-lock type bag it needs to be loosely tied. Then write the date on the bag so that you know when the pre-treatment was started.

    The seeds first require a period of warm pre-treatment and need to be kept in temperatures of 20°C for a period of at least 4 weeks - it is not critical if it lasts a week or two longer than this. During this time make sure that the pre-treatment medium does not dry out at any stage or it will be ineffective!

    Next the seeds require a cold period to break the final part of the dormancy, this is easily achieved by placing the bag in the fridge at (4°C) for at least 12 weeks. It is quite possible for the seeds to germinate in the bag at these temperatures when they are ready to do so, if they do, just remove them from the bag and carefully plant them up. When the period of pre-treatment has

    finished the seed should be ready to be planted. Small quantities can be sown in pots or seed trays filled with a good quality compost and cover them with a thin layer of compost no more than 1cm deep. For larger quantities it is easiest to sow the seeds in a well prepared seedbed outdoors once the warm and cold pre-treatments have finished and wait for the seedlings to appear.

    It has also been found that fluctuating pre-treatment temperatures can give the best germination results and I have myself had excellent results by keeping the mixed seeds in a cold shed through the winter for the cold stage of their pre-treatment and allowing the temperature to fluctuate naturally. Ungerminated seeds can have the whole warm and cold process repeated again to enable more seeds to germinate.

    Do not expose newly sown seeds to high temperatures (above 25°C). Keep the seedlings well-watered and weed free. Growth in the first year is usually between 20 and 50cm depending on the time of germination and cultural techniques and developing seedlings are usually trouble free. Allow them to grow for 1 - 2 years before planting them in a permanent position.
