I'd be very dubious about zone 5; the region it occurs in is more like zone 8-9. At best, I'd be cautious about risking it below zone 7.

It is only a moderately large tree (to about 20m), and is very slow-growing; in the wild it is reported mainly from limestone crags where there is less competition from faster-growing trees.

For grafting, use douglas-fir or larch as a rootstock (use whichever succeeds better in your soil).

Trying to root cuttings is unlikely to succeed.

Hi Marshall,

Musser Forests has potted Douglas Fir right now.

That's var. glauca as well.

Thanks for the suggestions. I saw the tree today and I don't think it's the proper time to be cutting on it - too small and looked to me to be a bit stressed.

Hi

My tree growing in a pot 80cm, protected by a hedge, survived with -17°c (a short time) but I think it was the "deadline" as many of needles became brown and fell. But it recovered without damage and new growth appeared in spring and now it is in a very good condition. perhaps older tree can survive woth lowest temperatures.
So, my opinion is zone 6/7

Hi Zcabn,

Temperatures of -17° can occur in a bad winter in zone 7 very easily, and in zone 8 rarely. The zone system is based on average minimum temperature, not the extremes, and it is the extremes that kill plants.

In the severe 1981/82 winter, zone 7 areas of Britain and Denmark widely recorded temperatures of -23° down to -29°C. Zone 6 areas of southern Sweden got down below -30°C.

Are you in a position to share your source?

Does any of you know of a source?

Many thanks.

Hi Arauquoia,

You can get seed from Sheffields Seed.
Colvos Creek Nursery near Seattle will try growing some in the near future.

Hope this helps.

P.S. Did you ever find more interesting Araucaria species to try growing from seed? Thanks!
