The variety ‘Blue Star’ is a Juniperus squamata plant, which grows remarkably compact. The silver-blue to deep blue coloration of its needles makes it a very attractive plant for gardens or table arrangements. The top of the needles is silver-blue; the bottom is blue-green. The sharp needles are fairly large and closely spaced. ‘Blue Star’ grows slowly and stays stocky. This broad, low and compact conifer has a pointed star like appearance.
The origin of ‘Blue Star’ is a Juniperus squamata plant, 'Meyeri’, which grows remarkably compact. This silver-blue, bush-shaped cultivar can grow a few metres high.A specimen, which appeared to grow more and more densely, was discovered in approximately 1950 in the substantial stock plantations on the Gebr. Hoogeveen in Reeuwijk. From two extremely dense cuttings, the South Holland tree breeder made his new acquisition. A German visitor suggested that the breeder call the newly cultivated variety ‘Blue Star’. The stocky growth is commonly associated with a witches' broom. The broom-like growth of the branches is caused by a mould or other micro-organism. This phenomenon also occurs in other wood crops. Sometimes the compact form of ‘Blue Star’ is also attributed to its ancestry.
'Blue Star' was awarded with a 'First Class Certificate' by the inspection committee of the Royal Dutch Association for Cultivated Forests in 1964. The Royal Horticultural Society (RHS, London) crowned the conifer with the prestigious ‘Award of Garden Merit’ in 1984. After the system of awards was revised in 1993, the British organisation once again granted an 'Award of Garden Merit' to ‘Blue Star’.
