There are reasons you don't see certain plants in people's yards. It might be susceptible to a disease or takes over or something.
This is a plant called Sweet Broom or Genista. It gets beautiful yellow pea flowers in Spring and is always in the nurseries then in full bloom. But you don't often see them in gardens. Why? Because they get a caterpillar that will defoliate the whole plant and kill it! Most folks don't notice the caterpillar until it's too late and wonder why the plant died. One could spray BT(Bacillus thuringensis) to kill the pests. Or one could resist even planting it and buy another plant. Just a suggestion.
