You can grow a meaningful amount of food on a single apartment balcony in Johannesburg, and the numbers work out to roughly R500 worth of fresh produce every month once your plants are established. Not because balcony gardening is some kind of miracle, but because the most expensive items at the supermarket, fresh herbs, salad greens, tomatoes, chillies, and spring onions, are also the easiest and cheapest things to grow in containers.

Walk through any township, suburb, roadside verge, or vacant lot in South Africa and you will find blackjack. It grows in pavement cracks. It grows in abandoned fields. It grows along railway lines, in garden borders, between rows of maize, and in every patch of disturbed soil from the Cape to Limpopo. Every South African knows it because of the tiny black seeds with barbed bristles that stick to your socks, your trousers, and your dog's fur.

Imagine a food crop that you plant once and never have to plant again. A crop that survives drought, frost, poor soil, and total neglect. A crop that produces kilograms of nutritious tubers underground while growing bright yellow sunflowers above the surface. A crop that spreads on its own, feeds your family through winter, and actually becomes harder to get rid of than to grow.
