There are a number of methods of flower preservation including hot air drying, silica gel drying, freeze drying and pressing. However, the most common, least difficult and consequently most widely favoured, is hanging small bunches in a well-ventilated area away from direct sunlight. We have a couple of vases of dried flowers and grasses. I'm no expert on suitable plants for drying but in our displays I can recognise lavender, poppy, yarrow and hare's tail grass. In the past we have had teasel and Physalis (Chinese Lanterns). I photographed a detail from one of our vases as I cast about for a subject on a recent wet and dull day.
