Hi. I know that euco will grow back from the stump after you've dropped a frost damaged tree - never dropped a good one but i guess that it might. Eucos are not all the same with regards to frost. The wife has a fine gunni - not seen any similar around here. she grew it from seed bought from snowdonia (Wales ,UK) and it has prospered in an exposed site in which locally sourced stuff has died. Never tried climbing it but, it's all smalll springy little branches so, not much to work with. You have to top it off quite low to keep the chubby juvenile leaf - hope some of this helps. Malcolm
