sal, do you expect it to survive there? Florida can get some pretty bad freezes at times....

Being prostrate i can cover it if vet it if we get too cold. Last 3 winters have not been a problem though. I have A. bidwillii, A. Cunninghamii and A. angustifolia nearby doing fine with no damage with lows of 23 F.

Do you think it will develop a vertical sprout at the base at some time?

I'm not familiar with propagating Araucaria, but I have rooted a lot of the glauca form of Cunninghamia lanceolatas from branches and tops. The cuttings from leaders go straight up. The branches are reluctant to go vertical and eventually will sprout a new leader from the base that goes straight up. I call the branch starts 'dumb' cuttings because they take so long to learn to go up as opposed to 'smart' cuttings from a leader. Sequoia sempervirens has the same problem.

I had to look up plagiotropy. :-) Thanks!

No, there are no examples of Araucaria branches ever developing orthotropic shoots.

Some rooted branches are known to be over 50 yrs. old and still plagiotropic

Thank you, salicaceae.

Very cool, I want one!

Very cool! Have you grafted any other species of Araucaria "centipedes"?

With all the crazy growth regulators and plant hormones available these days, can nothing act as a trigger to start them going upright again? I guess no one has exhaustively tested them, since it is of little commercial importance.
