John Bryan asked about soil-warming cables in the open ground, which always 
sounds like wonderful luxury. I have come across it only once, in the garden 
at Waltham Place, a mile or so from where I write in Maidenhead west of 
London. The owners are the Oppenheimers, of De Beers fame, so they can 
afford it: just a shame they only grow hardy plants in those beds! (Canna & 
Tradescantia pallida, both of which in recent years at least can be regarded 
as hardy hereabouts.)
