Here's an idea. Instead of buying a last minute bottle of wine to take to a party you've been invited to, how about potting a plant for them? I know it sounds time-consuming and daunting, but you can pot a bulk amount of plants and take some as you go! I mean, summer is the time to do it when there is so much going on. I got the idea from my dad a few weeks ago when I was home in Michigan. He bought a flat of different basil varieties (lemon, etc.) from his local nursery and some simple pots from the dollar store. Obviously, you don't have to use them right away. You can care for them yourself until the party day.
Make sure you soak the seedlings in water before planting them so they are quenched and ready to go! He mixed half fertilizer with half potting soil. Don't be scared if the fertilizer bag says "manure" on it; it doesn't smell like manure. You should probably wash your hands after handling it though, to be safe. :P I added images of the mixes my dad used below. He also added mulch to the top for not only a more finished look, but also because it helps hold moisture in the plant. See apartmenttherapy.com's creative ideas for mulch.
I hope you try it!
