Where can I find food grade rose petals?

DH loves pavlova so I'm making him one for his birthday cake in a couple of weeks.
I've found a recipe for a rolled pav with rose cream and strawberry. It calls for sliced unsprayed rose petals.

Where would I find some? I know from watching House that florist/supermarket flowers are bombarded with weird chemicals so I don't think they fit the bill.

I just planted some rose bushes under our windows but unfortunately I don't think that any of them will be in bloom by then.

Also for cooking should one use a fragrant rose or a non-fragrant?

some cake decorating suppliers should be able to help

Oooh, you could go to those specialty tea shops and get rose tea which consists of dried buds.....Oh but if you actually want the petals I would probably also suggest a specialty cake shop ?? Hope that helps ?

Are there any in bloom in the neighbourhood?

I've been keeping an eye out Lulu but I haven't seen any. At this time of year they're generally cut right back. The people down the road have an amzing rose garden - when it is in bloom you can smell it all the way up the street but they don't have anything at the moment.
If I see a rose it's not safe from my little scissors lol.

Herbies spices do rose petals chloe..... If there is a deli or something near you with a good range of Herbies' spices you might find them there. Their 'headquarters' are in Darling St Rozelle if you are near there.

Pariya food sell them, and they have an online store which is full of exciting things. I think Herbies can be purchased online too.
