Nanostructures in the forms of varieties of vegetation are reviewed, in particular nanotrees and their agglomerates, nanobushes, nanomushrooms, nanoflowers, nanograss, and nanosheafs, among many others. Synthesis methods, influence of reaction conditions on the structural types of products, properties, formation mechanisms, and current and future applications are discussed. These nanostructures possess a series of useful properties (magnetic, semiconducting, field-emission, etc.) and applications, mainly in catalysis, as well as for creation of nanomaterials, solar cells, and in medicine for tumor treatments, among other uses.
