3. Sow in a well draining, rocky soil mix.
4. Keep in a cool, bright location with minimal water.

This tree prefers to grow in isolation or with other hardy alpine species that do not compete for limited soil nutrients.

D'où vient le nom

The specific epithet longaeva means long lived, referring to the extreme longevity of the species.

Bon à savoir

They grow very slowly in harsh, high altitude conditions.
The wood is extremely dense and resinous, which helps it resist decay for centuries.
They are often found growing on rocky, alkaline soils where few other plants survive.
Their twisted, gnarled appearance is a result of centuries of wind and ice exposure.
