It is funny to me to talk about plants currently in our yard because we might have something like 5 living plants, a few trees and a whole lot of dirt. One of our trees in the backyard we were thinking about taking out because it is growing into another tree. I had no clue what tree it was as I’d never seen any like it in our area. This month though it started blooming and the flowers helped me identify it as a shrub pruned into a tree. My mother-in-law also really likes plants and told me that it is a Mock Orange (Murraya Paniculata).
The Mock Orange plant (and the tree shaped shrub) seems drought tolerant once established. We have lived here for months without watering and it has scarcely drooped. In fact it seems to have quite a bit of new growth. Left unchecked it would get quite out of hand (but might be nice for a privacy planting). It has flowers that smell lovely!
