Stachys affinis

The tubers have a distinct shape and look a bit like a grub. When eaten raw they are crisp and sweet like a water chestnut. When fried they are more starchy, soft and sweet, resembling a slightly nutty potato or kumara. In France they are known as crosnes and are typically served braised in herbs and butter, which is our preferred way to eat them. They are a great brain food.

Order is for a starter bag of about 5 tubers.

Growing instructions can be found below. Frost tolerant as they go dormant over winter.

Skirret (Sium sisarum)


Skirret was a reasonably well known plant in Europe from the middle ages into the 19th century. It has names in many different European languages and most of them appear to translate into some variation of “sugar root”. It can be prepared similarly to carrots. We love it simply fried in some butter. It is sweeter than carrots and beautifully creamy and soft when cooked.
