based off another thread about not putting real flowers on cakes, i was wondering, what flowers should NOT be put on cakes because of possible poisining or other reasons?  I had nevr really thought about it before bc i've never actually used real flowers on a cake before (just haven't had that bride yet) but i guess it would be good to know which flowers are better off a "no no".. i'm sure the florist would know, but i don't want to always bet on them letting me or the bride know...

If you ask me... any that aren't edible and organically grown.  Florist flowers are all grown using pesticides and chemical fertilizers.  http://homecooking.about.com/library/weekly/blflowersnot.htm this site has a good list.  You'll notice most of the more popular flowers used in bouquets.

If you google "edible" flowers and "inedible flowers" you will get a list.   I printed it up and keep it in my book.  I know Hydrangeas are a big no-no...I think Cala Lilies are on the inedible list too.   Both are popular bridal choices and I've actually seen these live flowers on cakes....scarey!!
