Si sobrevive, en principio ramificará en la zona dañada... Mira: http://davesgarden.com/guides/articles/view/539/ Lo que dice: "Frosts down to 28F [= -2ºC] rarely are a problem for most of these cooler-hardy species, but temps down to 26F [= -3ºC] or below will usually cause severe damage to the trunk/caudex. Last year all most of my outdoor Pachypodium saw 25F-27F and had significant damage to the degree that new growing centers had to start forming at the point of injury. Some proceeded to rot from that point on down. If a Pachypodium gets this sort of frost damage, it is recommended they be removed from the offending climate situations (i.e. dug up and moved indoors, or move the whole pot indoors if in a pot), preferably in a south-facing warm window for recovery. Apply rooting hormone to the injured area and do not water the plant for a long time. Most will recover and at least one (usually several) new stems will grow from the injured site. Sometimes this is a good thing making the plant more interesting. However it can take years if not forever for the unsightly blemish of the frost-scar to look better."
