Hello Peter,
thank you very much for this detailed information on frost hardiness of 
Albuca shawii and Ledebouria cooperi. Do you have similar observations 
in other species?
By the way Baker was very unfortunate in his taxonomic instinct 
concerning this Albuca species: he described it under six species names 
which he placed in all his three subgenera of Albuca. The oldest and 
thus correct name is Albuca tenuifolia, one year older than A. shawii, 
see the following linkfile:
