Road Trip

Hello, I planted it in shade and it grew higher then expected and did not trail very much. It was very healthy but the color was much darker then the picture. I always plant impatients behind the trailing plants but the Road Trip overpowered them so the resulting look was not what i had planned. Could you suggest which of your trailing plants might give me the look for which I was aiming. The wall is about 30” high. Thank you Jeff Bulman
