wedding craft: centerpieces

I am not a fan of cut flowers. Especially the ones that travel long distances to get here. Not so earth friendly. So I have decided that the main part of the centerpieces will be potted. I will also include local cut flowers to add color. This is all I know about them so far:

succulents
lavender both dried and potted
moss
mason jar candles
fresh cut local wild flower in mason jars
mason jar terrariums I love terrariums and would enjoy making them. However, I’m not sure if they’ll fit.
christmas tree trunk slices (for table letters)

Here are some centerpieces that I like:
