The First Meadowsweet of the Season

This almond-y, cucumber-y and generally summer-y scented blossom is a great wild flower to look out for. It's tell tale red stems set it apart from similar toxic umbellifer plants, along with it's strong scent. The flowers look like enlarged elderflowers and the leaves are similar but distinctly ribbed.

It was traditionally used to flavour mead in the past but you can infuse it into rice pudding, make cordial, cookies, flavour gin with it and even make wine.
Basically use as you would elderflowers.

Not only is it beautifully fragrant but has many useful health benefits.

It is said to be used to stop bleeding, vomiting diarrhoea, and excessive menstration. 

It also contains salicylic acid which is effective for pain relief.

It's also used to treat heartburn and stomach ulcers (source).
