Herbals are vastly underrated , and remain largely unknown, except for those who have taken the time to study them, and their medicinal properties.
Most modern pharmacology has been initially dependent on floral properties.
I like the idea of "dual purpose" plants like 'rugosa roses' : numerous flowers, rose hips for vitamin C, but also for an impenetrable hedge when planted closely.
Yes that hedge thing was a factor too. So far, though Hubby has avoided my suggestions that we plant enough to do that.
