This is my 6 year old Wollemi Pine (Wollemia nobilis). For anybody not aware of the extra-ordinary story of this tree, it was discovered in 1994 in a remote part of the Blue Mountains, about 100 miles from Sydney. An exhaustive search of the area revealed only 3 more specimens than the 70-odd mature trees in the original location. They turned out all to be genetically identical. It belongs to a genus thought to have been extinct for a very long time. In terms of tree evolution, it is truly primitive. It only survived at all because it is adapted to tolerate very low light levels. Its ancient cousins once covered the entire area around the south pole (the earth was warmer then) and so it had to cope with weeks or months of total darkness. They were growing at the bottom of a very deep gorge, right next to the cliff, mostly in 100% shade.

Anyway....after being kept in a top security lab for ten years they were finally released to the public in 2006. This is one of the first batch to go on non-auction sale in the northern hemisphere (late 2006). When it started producing cones last year I could hardly believe it - very few conifers reach sexual maturity this early. But that is part of the joy of owning one of these babies - nobody knows how they are going to behave under various different conditions in different parts of the world, because the only mature trees are in one place and nobody has ever watched a wollemi pine grow up!

That's a beauty of a wee tree :)
How frost hardy is it ? and will it do not only cold, but sodden well soaking too ?

cheers,
Toddy

It still manages to grow at a stable temperature of -5, but it normally shuts down for the winter by protecting its buds with a thick layer of protective gum (this smells wonderful and can be burned for the smell, you can see one bud covered with gum in the picture of female cones.) There are no reports of trees in the UK failing to survive last winter, but one report of slight browning of the foliage at -17 in Lancashire. In excessively wet conditions it can become prone to fungal infections.

It would be much bigger if it wasn't in a pot, BTW. I plan on finding it a permanent home soon.

Beautiful looking plant, will it take cuttings or can the seeds be propagated at all ?

I tried taking cuttings, but no luck. It can be done, but it is not easy. You have to get the conditions perfect.

The seeds (if I get any) should be viable. Wild-collected seeds have grown. Although it looks like the grove of 70 trees in Australia might even be one giant super-organism, rather than seperately seed-produced individuals. This species coppices naturally - it has multiple trunks and keeps sending up new trunks from the old roots. This means one individual tree is almost immortal.

Not yet lots of new growth they look great with the different shades of green

The colour differences are partly because they produce two different sorts of foliage, depending on light conditions. There is two-bladed growth for lower light conditions and four-bladed growth when there's more. It is another adaptation to living at the pole, I think - to take best advantage of the 24 hour daylight in the summer.
