I'm skeptical even with a special variety. Hawaii is mostly a hardiness 11 zone. To me success is doubtful but maybe in Volcano village or slopes of mauna loa somewhere.
There are fundamentally two kinds of garlic: hardnecks and softnecks. In the simplest terms possible, hardnecks are the most rugged and cold hardy of the garlics. They grow best in Hardiness Zones 1-5. In order to form healthy bulbs, they need to experience at least 10 weeks of cold. This period of cold exposure is known as vernalization. If the garlic plant does not experience a sufficient period of vernalization, it will not produce a bulb.
Softnecks are less cold hardy than hardnecks. Most softneck varieties grow best in Hardiness Zones 5-7 with a very few varieties able to form bulbs in Hardiness Zones 8-9. Softnecks must also experience a period of vernalization, but it does not have to be as long nor as extreme.
