Dye plants are those from which we can obtain dyes that we can use to dye various things, especially textile. Until the second half of the 19th century, only natural dyes were used, then they were replaced by synthetic ones. Today, due to the desire for greater sustainability, less impact on the environment and greater health safety of people, we are returning back to nature. Advantages and disadvantages of dye plants are described in this thesis and also their importance in the past and today, since they are an increasingly current topic in textile industry. A list of the most common dyeing plants in Europe and also detailed descriptions for woad (Isatis tinctoria L.), dyer’s knotweed (Polygonum tinctorium Ait.), madder (Rubia tinctorum L.), weld (Reseda luteola L.), dyer's chamomile (Anthemis tinctoria L.), wild marjoram (Origanum vulgare L.) and goldenrod (Solidago spp.) are included. The literature showes that the main problems in the return of the mass use of natural dyes are the low content of dyes in the plant, bad fastness properties of natural colorants and their narrow range. Colorants of the future will probably result from an optimized combination of all the different types of resources of our globe, including recycled ones.
