It happened here at Colesbourne Park in the hard winter of 1962-63 when the greenhouse containing the historic collection of H.J. Elwes' Nerine sarniensis selections collapsed in the snow and the plants froze to death overnight. It is a bad sign that the roots are gone & it may well be that the bulbs are also dead (but less obviously so). I would investigate closely and if there seemed to be signs of life keep the pots dry to minimise the chance of rot spreading in affected parts. Then repot in summer and invest in a non-electrical heater! It is well to remember that not only tender bulbs can be affected in this way; in 1991-92 almost my entire snowdrop collection was killed by being frozen in pots. Even the few that survived lost all their roots and took several years to return to normal strength. John Grimshaw Dr John M.
