Mashua (Tropaeolum tuberosum)

Mashua (pronounced Mah-shwuh) is an Andean tuber. A relative of the garden nasturtium, Mashua is one of the highest-yielding, and easiest-to-grow of the Andean tubers, and most resistant to cold. It also repels many insects, nematodes, and other pathogens, thus making it a valuable plant to intercrop with other species. The tubers about the size of small potatoes or big yams.
Mashua is high-yielding, even under conditions of almost no management. Even the leaves are edible!

You will receive 2 medium tubers or 1 large one (see image below).

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.

You will receive a seedling with some storage roots and shoots (see image further below). Simply plant into your garden as soon as you receive it and watch it emerge in spring. Growing tips are below.

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.
