Layered double hydroxides (LDHs) have received great attention for years in numerous fields. Controlled and flexible layer composition, as well as the vast assortment of possible anionic guests, and easy adaptability for multipurpose applications, have been some of the many reasons behind their extraordinary success. However, versatility does not only involve the composition or the dimensions of the crystals but also their morphology. Aside from conventional hexagonal, flat structures, three-dimensional assemblies have been reported with architectures dosely resembling those of flowers. The possibility of interconnecting the LDH nanosheets in rosette-like geometries has arisen the interest in finding new ways to control, modulate, and guide the particle growth obtaining hierarchical structures to be adapted to specific targets. This review is focused on describing the different strategies implemented to build flower-like assemblies, and on investigating their applications, looking for specific advantages of the use of a three-dimensional architecture over a bi-dimensional one.
