I value that they are still easily and cheaply available, as I still call on them for use often. I usually find it stored below the spice racks. Usually the store runs the same spices at varying price ranges. I think it's unfortunate how little attention some pagan authors have payed to the correspondences and uses of common, inexpensive vegetables. For example, the cucumber is aligned with the moon.
Peppers usually align with Mars.
Also, ginger root and other similar items are available in the produce section. I consider myself fortunate to have easy access to pomegranites and other slightly unusual items if I simply take the time to look around and see what is available to me. Flowers, especially roses.
