Welcome Fanny!
Many of my Ti have come out of HI and so far I have not had a problem with any viruses. I keep my new cuttings away from my established plants for the first 2 years just in case.
You may have heard the name Fred Stone (Special Ti Nursery) who is a breeder of Ti in HI. You will have to write:
Fred Stone/Deborah Ward
P.O. Box 1430
Kurtistown Hi,96760
Looking forward to photos of your Ti.
