Architects Sell A Lot Of Clivias
I have two planting areas on the patio. They are in deep shade all day, year round. I've tried various plants, but only Clivias manage to thrive in these areas. Architects and designers who "soften" patios by creating planting areas, if forced to plant and maintain them, would soon abandon the "soften" thing.
In the meantime, Clivias.
