Forget-me-nots are one of the pleasures of spring. They suddenly appear and their lovely pale blue, pink eyed flowers really tell that spring is well and truly here. They give clumps and cushions of colour in unlikely places, including between paving slabs and in the middle of displays of other plants and this habit is why many people consider them a pest. As soon as the flowers are over, forget-me-not shed millions of tiny seeds and they have an amazingly high germination rate, meaning that one forget-me-not plant can soon rule your garden. Harden your heart and pull out any plants in the wrong place but certainly make sure you dead head them at the very least before they can set seed, or your gardening hours will all be spent tracking them down and pulling them out – and still you will have forget-me-nots in your garden. This perhaps explains their name – you will never forget the person who gave you your first forget-me-not plant!
