Two questions about GROCERS

I will swap you them for a FACT about grocers I learned in my book on Krakatoa, viz. the name comes from the London Guild of Pepperers, who were licensed to trade spice in gross amounts. The spice must flow!

Here are the questions:

1/ Does the weird curly script used by all greengrocers on their handwritten signs have any kind of name? Did it inspire graffiti script at all (there are similarities) or vice versa for that matter? How do you learn it if you are a greengrocer? (This is several questions about the same thing, yes.)

2/ Vegetable names used only by grocers. Due to space reasons the stall outside Tooting Library called asparagus “GRASS” and cauliflowers “HEADS”. Any other examples?
