Ex Jim Archibald collection and to quote him re the parent plants - "Iran, Gilan/Ardabil, E of Khalkhal. 1900m. Alpine turf & moist gulleys. An intriguing form of this F. crassifolia relative from the Talesh range, near the border with Azerbaijan. Geographically, close to the Azerbaijan Talysh endemic F. grandiflora but different to it. Distinct as well from the cultivated, central Elburz forms, which grow about 300km. to the SE. Broad, glossy green foliage & big, pendant, pale-green bells with a variable, ghostly brown chequering or tinge. This has not been in cultivation before but this is a wet range & it does not seem to be unduly difficult."
