Thank you all for commenting and looking at those pictures.
@pino,
Yes, your zone will be too cold for the process.
@ Suzi,
Good! glad to see you are going to meet with Sue to collect the 'pair' and exchange views on the subject. Sorry, I had suggested the Calimyrna to be sure their seeds were fertile and grown 'in house'.
Enjoy the seminars and the tasting!
