Red dead nettle 2 (in bloom)
Botanical name: Lamium purpureum
Family name: Lamiaceae
Red dead-nettle is a relatively small annual weed found in gardens and crops in most parts of New Zealand. It can grow throughout the year though is found more commonly at cooler times of the year. It doesn't sting people despite having the word "nettle" within its name, which presumably comes from the leaves looking vaguely similar to nettle if looked at from a distance with poor eye-sight. Red dead-nettle tends to sprawl rather than grow upright. (Massey Uni Weeds Database)
Growing through the fence from a neighbour's garden. Listed as an edible weed on Julia's Edible Weeds website.
