Our Victorian ancestors used many flowers in the kitchen, and not just for table decorations.

Nasturtiums in salads was another favorite of the times. Oh, and of course! Captain Picard’s favorite: “Replicator! Tea, hot; Earl Grey!” That has lavender in it.
(Disclaimer: I’ve only had the candied violets, and used nasturtiums, but the other recipes look good. I have purchased from Spice House, and was satisfied but haven’t tried their lavender products.)
The whole subject of edible flowers fascinates me - I also think they make a salad or plate of great food adorned with flowers something very special.
