Those are simple and pretty!

Love this idea!  Dr_marigane, the instructions are on the right side of the screen when you open the article.  Paperwhites can grow inside on a windowsill in the pebbles that you plant them in. You can include some tips on aftercare for your guests in the tag that you attach to each bulb.

How long ahead of time do you add the water? [I don't really have a green thumb]. Do I add the water a few days ahead of time and then instruct my guests to plant the bulb within a few days? [Can these bulbs grow inside?] Is this favour okay for any wedding date, or does it lend itself more to a spring wedding (when the guests can actually plant the bulbs). I love this earth-friendly idea!

so cute
