"I like [the] look of Italian thin trees… I have smaller house, would that look odd for privacy? Bamboo trees other option in my mind."
And it occurred to me that landscape designers have a very methodical way of determining the best plant for a given spot, which we take for granted but may not be understood by everyone. I answered:
"Well, 'odd' is in the eye of the beholder — for the classical style of this home, in my opinion bamboo would have looked odd. But your tastes and opinions may be different, and that's OK too!
"There may be many different options to choose from to create privacy screening. A landscape designer would consider the specific conditions of your site before considering looks: sun/shade exposure, damp/dry soil, narrow/wide planting area, to name a few. Then within the set of plants that will thrive in those conditions, I would consider the functional attributes of the plants themselves: evergreen/deciduous, clumping/spreading, toxic/nontoxic, short/tall, fast/slow growth, high/low water needs, and so on. Finally, within that subset of plants that have appropriate features, I would choose the plants that fit the aesthetic look you prefer: the Italian Cypress used here work well with a formal, classic style, while bamboo species (and there are many!) may convey a more tropical or Asian feeling. Even the same plant could be used different ways: Pittosporum tenuifolium can be clipped tightly to create a formal hedge, or left loose for a natural, shrubby look.
"While the aesthetic choice is purely personal, the site conditions and plant attributes are non-negotiable. Figure those out first, and you may find that your plant choice is made for you. Good luck!"
