An attractive fast-growing large evergreen ornamental cedar with a loose pyramidal habit when young before developing more of a flat top with spreading branches as it matures.
Silvery-blue needle-like leaves to 30 mm long in clusters occur on spurs. Male cones with the pollen are erect about 5 cm long and release their yellow pollen in autumn. Female cones are more barrel-shaped and 5-7.5 cm long taking two year to mature.
A stunning specimen tree for larger areas. Tolerant of hot dry conditions, suited to cool and temperate climates.
Native to the Atlas Mountains of Morocco and Algeria in northern Africa.
Although seed can be sown most of the year in Australia seed is generally best sown in spring or autumn, avoid the coldest and hottest months of the year. The optimum germination temperature for germination is around 18-22°C
Germinates readily without pre-treatment but will generally give improved rates with cold stratification.
Cold stratification is recommended.
Cold treatment may not be critical for germination to occur in colder regions but should give increased germination rates in warmer climates.
This can be replicated by cold stratification in the refrigerator for 2-4 weeks. Alternatively over wintering in the garden in cold climates will assist germination.
General note: Seeds of many species are dormant and require specific conditions or pre-treatment for germination.
Do not be too hasty to discard seed that does not germinate, seeds will often lay dormant until the conditions are similar to their natural requirements for germination to occur. Containers put to one side will often surprise long after they were discarded.
