I’ve been craving greens this week so have been out looking for the summer weeds. Here’s what I found on my weed walk today. Most of these plants were growing wild.
Self heal, Prunella vulgaris. A low growing perennial, found in shady or damp-ish places. A member of the Lamiaceae family that includes mint. All members of this family have square stems and leaves opposite in pairs. This photo is a bit confusing because there is another plant there that looks very similar but with shinier leaves (self heal has matt leaves). I need to go back and find out what it is. This is a good instruction in paying attention and being certain that what you are picking is what you think you are picking. Unlike many others of the mint family self heal has no volatile oil. Tastes bland with a subtle pungency (that is stronger in wetter places I think).
Watercress, used to be Rorippa sp now Nasturtium sp (probably N microphyllum). Only very distantly related to the garden nasturtiums. Introduced from Eurasia, there are two species in NZ. Watercress grows mainly in streams with moving water, occasionally in boggy places. Most of this patch is flowering with long thin seed heads rather than leaves, but I manage to find a small handful of green shoots. A member of the cabbage family (Cruciferae, because the flowers always form a cross pattern), it is pungent and hot to taste.
Mallow, Malva sp. One of the smaller mallows, just about to flower. The leaves contain mucilage, which makes it cooling and moistening medicinally and food-wise. It’s related to the marshmallow and has similar uses herbally. The taste is bland.
Dandelion, Taraxacum officinale. Grows everywhere. Needs to be identified to distinguish from lookalikes. Young leaves that have come up after being mown I think. Or maybe first year leaves. Either way, bitter taste but not too bitter. Older leaves would be more bitter and so best to use less of them.
Plantain/kopakopa, Plantago major. Smallish, gnarly plants from another patch of mown grass, but still lush. Notable for their five or more distinct ribs with a thread inside when broken open at the stalk. There are two species in NZ, this one and another that has long thin leaves (P lanceolata). The narrow leafed one isn’t that great as a food, but both medicinal. Taste is green.
Fathen, Chenopodium sp, probably C album. A relative of spinach, quinoa and amaranth. It’s been a traditional food in both the Americas and Europe. This is a young plant – adults can grow up to a metre when seeding. It’s a common first arrival in new soils and grows prolifically, so if you like the taste it’s worth letting it seed in the garden (it’s not hard to weed out from places you don’t want it). Taste when young is bland, tarter when older.
Sheep’s sorrel, Rumex acetosella. One of the docks, a small, usually low growing one. It has a distinct double ‘tag’ at the bottom of each leaf. With a similar tartness as the docks but more lemony (like garden sorrel) and suitable for eating raw.
