Hardiness of Themidaceae, was fall planting and storage

Temperatures where I live in Derbyshire, England, rarely get below 10 F but
two years ago there were nightly temperatures of around 0 F, the winter
before was around 5 F, in each case for a period of  several weeks. These
are the temperatures I am stating as the limits of hardyness for these
plants, in the forms I grow.
Other species such as T laxa, B terrestris, T peduncularis all survived
these temperatures. These periods were largely without snow cover.
I do not grow the same range of material as Jane and others as they are
rarely available.
