Silver Spikefern

This big tree grows up to 72 meters (236.2 feet) tall and lives for decades, with the oldest known specimen being around 77 years old. It is very susceptible to disease and insect infestation.

It has a flexible, angular trunk covered in thick, smooth, light gray bark, and inside, the soft wood is silver.

The branches are short stubs, with dozens of twigs covered with small bunches of large, lime green or cyan needles. The needles themselves are resilient.

In late summer it produces giant, silver, spiky-shelled seeds.

The roots are thick and spread across the surface, as well as underground, and overall the tree is sturdy and rigid.

Forests of this species feature the trees packed together densely, with the space between them filled with thick undergrowth.
