Garlic farming in Parkville

Below is a picture of the some of the garlic 'farm' in Parkville. In its entirety is an area of roughly 5 metres x 1.5 metres which we have planted out with different varieties of garlic including;

Early white
Italian white
Early purple
Silverskin
American early white
Italian red
Glamour
Monaro Purple

The 'Monaro Purple' variety is visually the most dazzling as it has bright purple skin. I am a little worried that the garlic is not going to grow to full size. The stalks are a little thinner than the garlic i have growing at home in Macedon. The Parkville patch of garlic has a little less sun than the patch at home.
