Sorry I'm no good at creating great, effective business names b come-up wit ut here's a forum thread that has very helpful tips on how you can actually your store's name - importing/business-name-creation-help-needed-t5428.html
Can't say that I'm feeling completely creative this morning, but I'll throw one or two ideas out there for you to get the ball rolling.
Pots and Pansys or Pans and Petulas or Toasters and Tulips lol, OK, so you get the general idea. A name that combines both categories, while keeping it as cute and playful as possible. People tend to remember playful and cute names, and being remembered in business is never a bad thing.
Names like this will also give you some great branding ideas in regards to logo designs and such. Never underestimate the power of great branding. What do you think off when you think of Mcdonalds, I bet the golden arches come to mind!
Good luck with it and let us know what you come up with : )
