These are all lower water trees that I have used on many of our projects (I do development) that we like. If you need the actual specific names I can provide those as well but this should be a good start for you. My personal favorite is the non-flowering olive tree but that doesn’t go with everything. Some of these trees do flower and drop their leaves but most are fairly easy to maintain. Hope this helps!
