Longleaf Pine broom grafted
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:
