Last year I planted 10 kinds of mint in this planter (Garden, Moroccan, Tashkent, Ginger, Chocolate, Basil, Lime, Apple, Spearmint, and Pennyroyal). Since then, they have gone through attacks of mint rust and a horrible cold winter, but the survivors have dispersed their seeds and fraternised with their neighbours, creating a messy new growth of varieties that must be smelled to be identified. Some have disappeared entirely, others have flourished. I have identified small amounts of the chocolate, large amounts of the lime and spearmint, but have yet to locate the others.
