tan heat

Many succession [pineapple] plants are preserved through the winter in pits where no fire is kept; these should be managed with great care; a good tan heat is necessary for the principal warmth; good coverings on the glasses should by no means be omitted on nights, and when the weather increases with cold, let the outsides of such pits be well lined with litter to the top. If the heat of the bark bed is but moderate, let some hot dung be applied all round to keep out the cold and augment the warmth within side...

Bryophyllum calycinum is a succulent plant; it requires very little water, except when growing freely, and the pot to be well drained; it flowers best when plunged in a tan heat; rich loamy soil suits it well.
