It grows on lithosols or in any case immature soils, well drained, with a humid and cool climate.
It is a plant that resists temperatures of about -12 ° C.
It is a slow-growing plant which, therefore, is not suitable for parks and gardens to be set up in a short time.

This plant does not have a very common use, even for ornamental purposes also because it is slow growing.
From an ecological point of view, with a very large area (about 150,000 km²), and a very common presence, A. durangensis is not classified as endangered species on the IUCN Red List.
