Return to Self - Edible landscaping, food for mind, body & soul

The first things that come to my mind when I say Edible flowers are the nostalgic and familiar Moringa flowers and the Nasturiums which only read about. Now while loooking at the edible aspect of the common Hibiscus flowers I happened to know that the common, familiar crossandra flowers too are edible...(although I need to look for more refereneces to it) and tried them immediately as I have fresh kanakambaram flowers growing in our common area...the gourd flower is anyway edible.
