Herbstonne Rudbeckia

I had no idea what to expect of this plant for this year .. it set out HUGE leaves after I planted late Spring .. and the leaves were making some bug more than happy at mealtimes .. so I thought .. ok, stress from hot dry conditions and HAPPY bugs .. not going to do all that much .. but I was wrong .. it has flowered nonstop since it started and wow ! these flowers stand out like no body's business ! Great back of the border almost privacy screen size !
