Here's one I knew about but only saw in the supermarket for the first time today.
Simplified Chinese 一点红; Traditional Chinese 一點紅 (Mandarin: yī diǎn hóng; Cantonese: jat1 dim2 hung4).
Emilia sonchifolia, lilac tasselflower or cupid's shaving brush. Mostly used in Traditional Chinese Medicine (TCM), but the leaves and shoots are edible.
Note: The literal meaning of the Chinese is "one spot (of) red", which is blatantly untrue, as the 280 grams of greenery I bought contained not one, but two reddish flowers.
