If I’m asked what my favourite perennial vegetable is, I will struggle to only mention one (I wrote a book about my 80 favourites after all), but the one I will mention most frequently is the Caucasian spinach (Hablitzia tamnoides) as it has an interesting history, it was discovered as an edible plant in Scandinavia and remained a closely kept secret here until the 2000s, it provides the first spring greens together with various Alliums , its productive and probably grows best in cold climates!

This video describes how I discovered this amazing vegetable and its history in Scandinavia and in particular the role Swedish author Lena Israelsson played!
