Geraniums on My Window Sill

Today, since I stayed in for the better part of the day, I thought I would
show you what my very little garden looks like that sits on the window
sill.  Only Geraniums this year with 3 Air Plants nestled in among the leaves.
Someone gave me the Air Plants last Christmas
because she didn't know how to take care of them.  I don't either, but,
they seem o.k. ever since I put them in among the leaves of the other
flowers.  Anybody know any thing about Air Plants?
