Mouse garlic - Allium angulosum
This is a fairly slow-growing allium that has fleshy, strap-like leaves similar to garlic chives. It is very resilient to pests and diseases. It is deciduous, dying back in autumn but appears again quite early in spring. The leaves are the main edible part and they are very good cooked in stir fries or chopped and added to soups. They are also very good for lacto-fermentation, either on their own or mixed with other vegetables such as kale or beetroot. The bulbs are edible but they are small and fiddly and as the plant is slow to divide, they are probably best left to grow. The flowers lack the garlic taste.
We haven't yet been able to gather seeds from our plants, but propagation by division is easy (though it takes a little patience to wait until clumps are big enough to divide).
