@shutterbug49 Hi Shutterbug - It's a type of Eucalypt. This one can survive very cold temperatures and very dry conditions. It germinated in a crack in the vast granite dome and has managed to grow to this size while forcing the crack to get larger and allow other smaller plants to grow beside it. It's alive and doing well - but I've only shown the bottom section here. A lot of those older twigs etc will fall off and accumulate at the bottom. They are pretty impressive. Thanks for your interest. Cheers Rob
