and thank you for taking the time to read a stranger's gardening self inflicted struggle. I am new to this forum, so please excuse any intricacies I am not aware of. I've studied and researched this issue a lot, and all I am finding is conflicting information. Now, to the gardening issue:
My Zone: 9a. My garden is in Northern Greece. I experience generally mild winters (although frosts are not uncommon) and heated summers (~40 C)
I've got a corner with north and west facing walls. My home is situated to the direction of my west facing wall. There's an old olive tree planted there in a small bed, that has grown a lot. The west facing wall is the entrance of my home: a small one person gate, with a fence to a 2 steps stair, into the garden, to a ~6-8 meters long pathway with my garden beds (as you enter, facing west, as the aforementioned wall) left (a big one) and right (a small one with the olive tree and a simple shrub).
As you can understand, my north facing wall gets no sunlight at all, and my west facing one does the same. Nevertheless, I want something potted in that corner just behind my olive tree, something that will give that corner just a little pop of colour and vividness. On that corner, my mailbox also hangs from my west facing wall's fence.
I've decided to put a trumpet vine on that fence, and care for it so it does not get out of control. The fence itself gets some sunlight but the pot itself will not. On the same pot (more than 70 liters) I want to have another climber that will get itself on some wooden investment I have on the wall. My question is:
Will a Clematis vine flower in full shade like the one I am describing in a 9a zone?
