Longleaf Pine broom grafted

treeguy123(AL 7b)May 10, 2014

I found this Longleaf Pine (Pinus palustris) broom in late 2012. And I successfully grafted several scions to Loblolly pine seedlings this spring. Here are pictures of the broom and grafts, I'll have to come up with a name as well.
These should also be cold hardy in at least parts of zone 6, since it's from the natural northern range edge. The parents have probably seen short cold episodes below -10F or -15F (-23 to -26 C). As far As I know, this is the first cultivated Longleaf Pine broom.

Here are new needles emerging from the Longleaf pine broom scion buds:

The broom scions are grafted to Loblolly pine (Pinus taeda) seedlings:

Thanks. : )
They were grafted to wild Loblolly pine seedlings that have been naturally growing in ground for at least a few years now.

I collected scion on March 2nd (kind of late) but thankfully this has been a long cold winter, and these more northern stands I'm sure bud out later than most anyway. Removed needles, waxed, and put in fridge until wild Loblolly pine seedlings started pushing buds, then I grafted (Tried to wait until after the last freeze also). The scion buds have just started pushing growth in the past two weeks or so.

Can you provide more details about the waxing process?

That's an impressive accomplishment -- good work. Hope they do OK.

Longleafs here did OK after a zone5ish winter. Some windburn on oldest needles, but no bud-death. One had a double-leader up high, but the snow-loads bent one downward, solving the issue.

Thanks.
That's really good for doing OK through zone 5 type winter. I think this one has a good chance of needle cold hardiness to zone 5a or 5b being that it from the very northern edge of range in AL. Yours came from AL didn't it? I read that in a old past post.

Right, from a wholesale forestry nursery in the northeast AL mountains. They're called 'Montane' longleaf, and that nursery was working to get some of the mountain stands reestablished.

This is only three days of growth for another graft I made of this same Longleaf Pine broom (all grafted to Loblolly Pine seedlings):

3 days of growth animation for the broom bud growth: :-)
