I have grown I tectorum for 20+ years here in the
Kootenays of southern BC. Mostly I have grown it
in full sun, with wet springs and sometimes
falls, and hot dry summers. How well it survives
seems to relate to snow cover in winter, and how
hard and long the frost is in fall before snow
comes. It survives everything but with some attrition.
