blue Araucaria

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.

From April 20, 2010

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.

"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!
