More seeds?

I've discovered a new seed company, www.botanicalinterests.com, and have yet more seeds I'd like to buy. However, their website says that they currently accept US orders only, so maybe this list is just for daydreaming:

- sorrel (a perennial green, which I've had little luck finding as seedlings in stores - I only have one plant currently)
- watercress (which I've harvested wild, but have never seen this for sale before; it says I can grow it indoors in water!)
- amaranth edible red leaf seed (which I think will be similar to the aztec spinach we grew this past year)
- wild arugula (who knew there was a wild variety?!)
- yard-long bean pole asparagus (apparently not a true bean, but grows like one, and the unique flavor reminds some people of asparagus)
- bean pole trionfo violetto (a purple pole bean with a more sweet and nutty flavour than other purple beans)
- beet gourmet blend (a variety of types: bull's blood, chioggia, golden)
- carrot tonda di parigi (cute round carrots)
- strawberry popcorn (red kernels, but pop white!)
- edamame soybean (an earlier ripening variety)
- red winter kale (more tender and sweet than red russian kale)
- mustard ruby streaks (a mustard green, looks kind of like mizuna with narrow leaves)
- onion red amposta (why haven't I grown onions yet? this one is sweet and stores well)
- parsnip all American (because I've finally fallen in love with parsnips)
