This a very old Victorian Regal variety which means it has an old fashioned look. Tall and upright plants in those days were grown to be seen and this surely fits the bill. With its purple black flowers edged white and with a white throat, this one will certainly standout in your summer display.
Plants are supplied in a 6cm biodegradable pot. There is no need to remove this pot as roots will grow thorough it and the pot, which is made of fibre, will degrade harmlessly into the compost.
