| This is a blue Araucaria cunninghamii I grafted a couple of years ago. The blue 'form' (var. glauca) is found in certain areas of Australia (Magnetic Island) and also in PNG. The source of the scion was a seedling blue variant in a batch of green ones a friend raised. The graft is now growing happily in my garden and came through last winter (which was rough due to the wildly fluctuating temps) with minimal damage. I also have a graft of a blue A. heterophylla I will post. It is a plagiotropic one, so it will just be a groundcover. |

| Sweet, not a fan of ground covers, but a tree form, I am. Dax |

| "It is a plagiotropic one, so it will just be a groundcover." Forever? Can something like GA or another hormone force them to start a leader? A slew of weird synthetic ones are available from commercial greenhouse suppliers, although I think the majority of those are intended to stop a leader from forming! If you read research papers about them though, they use various opposite-acting hormones (only available from laboratory suppliers, unfortunately) to test their efficacy. Could be an avenue to explore. |

| Gosh Jason, you have the coolest stuff. I still have to come up with something to trade you sometime (no eucalypts at the moment). I have Cupressus austrotibetica or C sp Mekong River, maybe there's a slight chance you don't have one of those. BTW I have rooted A. bidwillii from a terminal shoot without much trouble, after it grew back with multiple leaders when it froze... going to try A. angustifolia next. I haven't tried grafting them. |

| I think if you check you may find that first cypress is just another Silbanym. Tying a shoot to a stake may produce a leader from the araucaria. |

| Yes, I have read that it is, but it looks different enough to me from C. duclouxiana, side by side in pots, to be worth collecting. |

| Thanks Ian - we have plenty of stuff to trade if you are interested. Send me a message and we can work something out. Glad you like these photos - I have LOTS more to show (and will when I have time). It is fun to show those from cold climates what warm temperate and tropical conifers look like. |

| As I love both Araucarias and blue plants, well done. |
RE: blue Araucaria

| Thanks - I do too. It isn't as blue now that it is getting bigger, but definitely glaucous. There are some super blue ones in PNG and even a blue form of A. hunsteinii, which is like bidwilii. Can you imagine that?! I really some material of that! |
