Corkbark fir 'Compacta'

Corkbark fir 'Compacta' is a cultivar of the Subalpine fir variety arizonica. It is noted for its exceptionally compact growth habit and attractive pyramidal shape. Compared to the parent plant, it grows at a significantly slower rate, which makes this cultivar a perfect choice for small gardens with limited space.

Subalpine fir 'Green Globe'

A semi-dwarf cultivar, subalpine fir 'Green Globe' is distinguished by its dark green, non-fading needles and distinctive growth form. When young, the cultivar is globe-shaped (thus the name), but it becomes more conical as it ages. A slow-growing variety, it makes a great choice for small gardens.

Subalpine fir is characterized by a svelte silhouette with a narrow, tapering crown and boughs that gracefully droop. Its branches boast a dense array of foliage, providing a lush appearance. Adapted to thrive in cooler, moist conditions, subalpine fir reaches maturity as a medium to large statured tree. The bark is complemented by wood that is pale and notably soft, though it succumbs to decay with relative swiftness. Subalpine fir's ecological role is notable, as it fosters forest growth on harsh terrain and plays a part in the conservation of water resources.
