I am new to gardening- I actually know nothing about it. But I went to an event that used plants as centerpieces because they were going to donate them to a local hospital after the event. I want to do the same at my black-tie wedding. I need ideas of what type of plants could be used at my October 2013 event in South Florida. Will Orchids work? What else is regional, colorful, and pretty? I was hoping to using red and teal as the wedding colors-- but I am open to anything. I would like to also send my guests home with a gardening gift bag so they can take plants home if they wish.
