Here's what I have so far. I'm going to use standard disposable plates (which usually have some kind of flower pattern on them) and clear cups leftover from Easter's dinner. It's family - no activities or crafts required. :p
I need some more sides - more veggies/fruits - maybe some kind of cold salad(s)?

baked beans

barbecued veggie and regular burgers

chips

potato salad

deviled eggs

veggie tray (colored peppers, celery, carrots, cucumbers)

Worm cupcakes (gummy worms, cookie crumbs, icing)

sparkly flower cupcakes (piped with clear sprinkles on top)

paper daisy lollipop favors (already have components, kids will make)

lanterns (leftover from last year) with paper butterflies (kids will make) and garden flags (already have) to decorate

daisy balloons

watering can "vase" centerpiece

iced mango ceylon tea
iced green tea - maybe ginger peach

Maybe do a pasta salad with roasted veggies? Make ice rings to float on your punch? Fruit kebabs? If you do cantaloupe, honeydew or pineapple, cream cheese dip is good with it. Roasted corn?

oh lets see, um homemade raspberry lemonade with an ice flower ring. For sillier kid things, you could do ants on a log, birdsnests ( i think choc or pb chips and chow mein noodles LOl-- you can find a recipe easily though i am sure). You could very easily make something with a flower cookie cutter-- maybe sandwiches?

Oh CUTE!!! Love that :)

I'm going to do candy for the kids' favors. Any ideas for a garden-y candy? :lol:

Picture of our "potted plant" brownie parfaits... they were SO good!

I have tons of more ideas, and want to look at yours more closely... But I am sick today... and need to get back to my tea. I will come back in the morning. :)
