They are as diverse in shape, size, colour, decoration as any flower. They are self-contained, yet everything is contained in them, however small, to make the tallest tree, the juiciest berry, the wheat we eat, the biggest sunflower, the rarest orchid.

Hold seeds in your hand. Feel the faint pulsation of life, no matter how dry, how hard and rigid they seem. Feel that faint warmth, the tiny voice that says. “I know. I am coming. Plant me”.

In your hand is magic.

Remember biology classes at school, as dry as these seeds, the dreary terminology of meristem and cotyledon and radicle? No-one spoke about miracles. Yet no-one understands the rapture of the “hooked plumule” until they see their first-ever home-grown seedling – maybe tomato, maybe a pumpkin – shoulder its way through the soil into the open air, then to unhook and open those first seed-leaves.

You stare, open mouthed. I did that, you think. I put that seed there. And lo, it is growing. It worked. In that moment, you are caught. You will see this happen again and again, pots of seeds, rows of seeds, the longed-for yet always somehow unexpected eruptions of “seed” potatoes breaking through the mounded soil. But always it will dazzle you, floor you, make you giddy with sudden brief joy.

It is the ultimate alchemy – the transformation of small hard mote into living organism. So far beyond the base-metal-into-gold aspiration of mediaeval alchemists, for it has succeeded. And it is a collaborative feat. You may have sown the seed, but the seed has made use of you, and you have grown.

From each seed is the potential for flowers. From flowers, the prospect of more seed through pollination. The promise of seed is the promise that we may eat again, that our children will eat. It is no less than the promise of survival.

In today’s world, a pandemic virus coupled with spiralling concern for an environmental emergency has got us all sowing seeds. An army of growers and gardeners is multiplying like dandelions. These aren’t the old-guard, nature-controlling gardeners. When the garden centres closed, we realised our children cannot afford to be at the mercy of a few big seed companies, or side-lined into dead-end F1 hybrids that will not produce viable offspring. We need seed we can collect ourselves, share, save, and keep for following years and new generations. Seed banks and seed libraries (a kinder term, that speaks of sharing and co-operation) are springing up across our land. Is there one near you? Can you start one?

We are a people terrified by the present, grasping for a past that was never really going to sustain us, and reluctant to look at the future, in case there isn’t one. Seeds, in their understated humility, their quiet, warm still voices, carry that germ of a dizzy rapture, that incredible potential.

Seeds are the promise of a future.
