Flower arrangement can be a valuable skill, and in many countries it is considered to be an art form, including the UK. Flower arranging is more complex than you might expect; at least it’s not just gathering a bunch of flowers; it is about arranging a combination of flowers in such a way that it makes sense from a design point of view. This can be tricky, as you need to consider lots of elements, from shape, colour, and smell.
Most of those whom learn the art of flower arranging, or floristry, learn it through the industry, usually in an apprenticeship. You can also take short courses in it, where you learn from a professional, although this isn’t really a complete education, and is unsuitable for those looking for a career in floristry. You can also take extended courses, where you can learn flower arrangement and flower and plant care.
