A lily is a term for any plant belonging to the genus Lilium, a wide and diverse group of herbaceous, flowering plants. Chiefly grown for decorative purposes, lilies make a beautiful addition to your garden and are a far less labor-intensive plant than other decorative varieties. Knowing the average growth height of common lily plants is an important part of planning the garden's physical layout.
In chemistry, a hydrate is a substance that contains water or its constituent elements. The chemical state of the water varies widely between different classes of hydrates, some of which were so labeled before their chemical structure was understood.
Hydrates, i.e. crystal forms containing water as integral part of the crystal lattice, are frequent and well recognised. Of the total of 596 810 crystal structures filed in the Cambridge Structural Database (as of May 2012), 88 470 structures, i.e. 15%, contain water, more than any other solvent.
