Well perhaps not buds but petals…
I love using dried rose petals in bath bombs – they look so pretty. I only ever make pure white bath bombs. I don’t like adding artificial colours (a la Lush products), it is not a criticism of artificial colours just a personal preference not to use them. The rose petals add a touch of colour and look pretty floating on the bath water once the bath bomb has fizzed away.
I have just finished drying out some rose petals. These are from shop bought roses. I do keep the roses as fresh flowers for a while but before they turn I remove the petals, lay them out on kitchen roll on a tray (the kitchen roll helps to absorb the moisture) leave them in a warm place and after a few days they are dry enough to store.
These will be put in a coffee grinder (that is just used for grinding botanicals for making skin care products) and blitzed a little. Not reduced to a powder but just to slightly smaller pieces and then stored.
As they are shop bought flowers they don’t add to the bath bombs in terms of smell (although I do add a few drops of rose geranium essential oil to them when bagged for storage).
Once some roses start appearing in the garden I will use petals from them and they do smell great so no additional essential oil is needed for the petals. This particular bath bomb I always scent with rose geranium essential oil and ylang ylang.
Have a good day.
