Newbie question- Vege garden location has no sun mid winter. No good?

We're gardening novices and we're trying to plan our garden layout for our new home. The climate is coastal subtropical - temperature and rainfall are quite consistent throughout the year, so I guess people grow food here all year long.
Near to the house there is a lovely location for a vege garden in terms of access. However, it  is on the southern side of the house (in the southern hemisphere), and for a couple of months in the winter it gets no sun at all. For about 9-10 months of the year it gets plenty of direct sunlight.

Does this lack of sun impact what I can do with it much?

In the subtropis things are different and you grow tomatoes in winter. But tomatoes need sun. Lettuced and everything green does not need as much sun. and the sun is much stronger were you live. There is a difference between dappled shade of a tree and shade from a house. Not every crop needs sun and you might be able to divide your garden.

I am not sure how things work in the tropics but where I am in north central USA I would try planting things that did not need as much sun in those "shady" months. Lettuce, Kale, etc ?

It sounds like even the likes of lettuce and kale will not grow where there is NO sun. A fairly large chunk of this prospective garden won't get even a minute of direct sunlight for a couple of months.

Should I just abandon this as a garden bed altogether? Or could it still be useful for growing something in the subtropics?

Ginger grow great on the shady side of the house, but it still needs a bit of sun.

I'd say, "Sure --- try it and see what grows".  What's the worst that can happen?  You waste $10 worth of seed.  No biggie.

It gets pretty gloomy where I am in mid winter. I would suggest planting cold- hardy crops as early as you can so they can finish their growing before thd sun disappears. But don't harvest straight away- "store" your crops where they're growing and harvest as needed.
I honestly don't know if this'll work for deep shadow, but it works for my winter where the sun is perpetually hidden by grey clouds.
Otherwise, that might be a good spot for composting or water storage.

Could a mirror be placed even further south to redirect the sunlight at least for part of the day?  I'm in Wyoming, so envy your 'problem'.
