DIY Herb Teas

I'm making a list of the different herb combinations/recipes that I come across to get an idea of the plants that I have that can be used or that I need to grow. If you have any recommended combinations, please add them to this thread. 

First up, from the Twinings Cold infuse teas I've been given:-

Raspberry & Hibiscus + Rosehips, apple pieces, beetroot, Roasted chicory Root.
Mandarin & Rosemary + Stevia leaves (Like this one a lot).
Watermelon, Strawberry & Mint + Hibiscus, Beetroot, Rosehips, orange peel.
Pomegranate and Elderflower + Lemon Balm, Beetroot
Lemon, Lime & Green Mate + White Hibiscus, Stevia Leaves
Watermelon, Apple & Matcha + Green Tea, White Hibiscus, Stevia Leaves.

I "think" that the beetroot may be the colouring in the red teas so I'm not going to lob a slice of beetroot into my cup!
I'm going to start saving orange and lemon peel, drying rosemary & lemon balm, gathering elderflowers and rosehips in season and trying to grow Stevia and Hibiscus...............for a start.

Stevia is quite easy to grow on the windowsill or in the greenhouse. I grew it this year but didn't know how and couldn't be bothered to find out how to process it.
Its dried its leaves naturally because I forgot to water it near its end.
