Most, if
not all of the specialty trees out there are grafted. That means a nurseryman
saw something unusual growing among a bunch of trees of the same genus.
Let’s
say its branches were weeping downward. He would then take that oddity; dig it
up and transplant it where people could give it extra care. They would then
watch it to see if the genetic were strong enough to actually survive; and if
it would continue to grow with its branches weeping downward.
If all
goes well this plant will be a “mother plant” from which cutting would be taken
and grafted onto same species trunks. They will care for these graftings, making
sure nothing grows beneath the graft; for if it does that stem it will be what
that trunk would normally produce, a normal upright branch. This is why some people’s specialty tree has a green leafed branch growing within the red ones; or a “straight up” branch is growing out the top of a weeping tree (as pictured below). If they were to look close at the graft markings they will see that this stem or branch is growing below the graft, and out from the trunk the odd duck was grafted into.
If this
happens just cut it off; the sooner the better.
Your specialty
tree is a genetic misfit, a quirk of nature so to speak, but a gold mind for
the experienced Nurseryperson.
