Back to the greenery after a short respite. (I know I said Monday, but an event has been cancelled,so here I am.)
Lycium chinense
These are the shoots of the wolfberry plant also, more recently, known as the goji plant, source of the goji berries touted by every know-nothing "health expert" as a so-called superfood.
Known in Chinese as 枸杞菜 (Mand: gǒu qǐ cài; Cant: gau2 gei2 coi3, literally goji vegetable) or 枸杞叶/枸杞葉 (Mand: gǒu qǐ yè; Cant: gau2 gei2 jip6, literally 'goji leaf').
Young stems are also edible, but more normally the leaves are stripped from older, woody stems. They are simply stir fried or added to hot pots. Another good'un.
I'll deal with the berries separately in due course.
