We have this big bush outside our house in Portugal which looked amazing when we bought the house. We don\'t know how to look after it, and it\'s slowly becoming more twigs than leaves. It\'s in the south of Portugal, Algarve is a hot Mediterranean climate.

I don\'t know what it\'s called. In one of the photos, there is a small flower. I tried googling it and maybe not my lucky day to know the name of this plant. I hope someone can identify this plant. :) thank you.
