Flowers provide a temporary splash of colour in the garden, but foliage plants will give you colour all year round. There are many beautiful conifers which have blue foliage, including some dwarf varieties. They create a stunning and very classy look in the garden, and they grow particularly well in the cooler parts of Australia. Here is Don’s selection of some of the best blue foliaged conifers available.
Popular for ornamental planting in large parks and gardens, Cedrus atlantica is native to the Atlas Mountains of Algeria and Morocco. C. atlantica ‘Glauca’ is a lovely cultivar with rich, waxy blue leaves all year round. Like the species, it is a very big plant, growing to 20m (60′) or more. It is very hardy in most zones of Australia except for tropical and subtropical regions.
‘Blue Snake’ is a blue creeping dwarf Himalayan cedar which grows less than 2m (6′) high. It has bluish-green weeping foliage, and can be staked for a pendulous form.
Don thinks ‘Blue Ice’ is close to the best blue coloured conifer ever. It has silvery blue foliage and is a wind-hardy, drought tolerant, slow growing conical tree to 10m (30′) plus. Although it does grow tall, it can be trimmed into a hedge and kept to a smaller size. It is at its best in Sydney, Perth and areas south.
This is one of the new wave of exciting new blue conifers. ‘Blue Arrow’ is narrow like a pencil pine but it only grows to around 5m (15′) tall.
This is a prostrate plant growing less than a metre tall, with blue foliage which changes to a bronze purple colour in winter.
Don looked at a grafted specimen, but normally ‘Blue Star’ is a groundcover growing about 75cm tall and 1m (3′) wide. It has silvery blue, short spiky branchlets forming a globe-shaped bush.
While not really a true dwarf blue spruce, ‘Fat Albert’ is very slow growing. It will only reach about 2m (6′) tall in ten years, but it eventually grows into a full-sized blue spruce. ‘Fat Albert’ is best suited to the cold areas of Australia.
‘Minima’ is one of a number of miniature clones of Pinus strobus, a North American native growing to around 35m (100′) tall, with blue green foliage in clusters at the end of whorled, horizontal branches.
For a low growing, dense plant, Don likes Juniperus squamata ‘Blue Star’. He is sure another juniper, ‘Blue Arrow’, will become very popular for narrow areas, and for a large conifer, he thinks you can’t go past the hardy cedar, ‘Blue Ice’. Don also pointed out that there are some blue foliaged conifers that don’t perform well, such as Alligator Juniper (Juniperus deppeana var. pachyphlaea ‘Conspicua’).
