Answer 1

We are based out of the US, so I am not as familiar with your weather patterns, as I am ours. From what I DO know- There is always a lot of rain.

With wet weather, there is a need to choose plants that will adapt to that. The other issue is that they will require a cold period throughout the year. These shrubs are only suitable for our USDA zones 2-7. The coldest your country gets, in any area, is equivalent to our zone 8. This is just a little too warm for this shrub, year round. (Rather, it does not get cold enough for this shrub). Much of your country is zone 9, though. This is too far out of the range for this shrubs to be comfortable.

All of these things, together, will make it very difficult to keep this shrub alive for long.

I would choose something suited to your area.
