I don't know how old you are and what is your goal but you have to start somewhere.
If JBP is hard to come by in your area the I suggest start with seedlings. I did that many years ago so I do have plenty to play with. I also just start a new batch from seedlings I got from Eric S.
I don't think trees remember if they coming from different zones as where they will be growned. My original batch came from Matt Owinga which locate in Maryland. They did just fine.

Great trees! I have plenty of time to grow some, just a space issue. It's why I usual stick to buying trees, because growing can be difficult due to not enough room. As for the trees "remembering" the climate, I am not sure I would say it that way. This was a topic I discussed with multiple Bonsai nurseries (including plant city Georgia and a JBP nursery from a northern state, I think ohio?). They both recommended given a year or two of allowing the trees to acclimate to our weather.
The climate acclimation is certainly something that can be seen in trees and animals. I am referring to processes that are more on the basis of epigenetic. Genes that are turned on and off due to environmental exposures. Sunlight exposure and temperature are major factors that control tree behavior. This leads to a marked change in energy and resource storage and use. If a tree continually decreases its metabolism for 6 months of the year for 10 years of its life, to then grow in an area with 2 months of colder weather is a drastically adjustment. Ryan Neil discusses this period of rest for pines frequently, even in JBPs. This contributes to our alternate candle pruning timetable in South Florida.
Ultimately, my skill level plays a huge role and my experience with pines is drastically less than tropical species just due to availability in my area as I discussed before. My ability to bring them to the warmer climate was probably not sufficient. Hearing you obtained yours from Maryland is great, and I will look into it. The nursery from up north said that he sells to florida not infrequently so clearly it is possible. I just need to learn how. Either way for a project like a forest which requires multiple trees I want to maximize my chance of success.
