I grew 4 types of geraniums this year and am very impressed with one that is a Interspecific called Calliope Dark Red (cross of Ivy & zonal) from Syngenta. The Interspecific types are genetic crosses between a zonal & ivy or zonal & regal geranium. Calliope has a nice mounding habit that works well in a mixed basket. The flower clusters are quite large like a zonal, but not quite as around ball shape. The leaves are large like a zonal, but no markings with similarities to an ivy geranium. Anyways, the Calliope Dark Red is my favourite annual this year. Love the colour and performance. I planted the Calliope Dark Red in hanging baskets, planters and direct in ground. It looks awesome in all locations. They are a big plant. Next spring, there will be another Interspecific variety that will be in stores called Cumbanita from Dummen Red Fox. Put them on you shopping list for next year. In the picture, I have them (Calliope) in the barrel planters & in the window basket.
