Sepals are usually green, regardless of petal color. However, the term ''[[tepal]]'' is usually applied when the petals and sepals share the same color, or the petals are absent and the sepals are colorful. When the flower is in bud, the sepals enclose and protect the more delicate floral parts within. Morphologically they are modified leaves. The calyx (the sepals) and the corolla (the petals) are the outer sterile whorls of the flower, which together form what is known as the ''perianth'''.<ref name=Davis1979>{{Citation | last1 = Davis | first1 = P.H. | last2 = Cullen | first2 = J. | year = 1979 | title = The identification of flowering plant families, including a key to those native and cultivated in north temperate regions | pages = 106 | isbn = 0521293596 | publisher = Cambridge University Press | location = Cambridge }}</ref>
There exists considerable variation in form of the sepals among the [[flowering plant]]s. Often the sepals are much reduced, appearing somewhat awn-like, or as scales, teeth, or ridges. Examples of flowers with much reduced perianths are found among the [[Poaceae|grasses]]. In some flowers, the sepals are fused towards the base, forming a ''calyx tube'' (as in the [[Lythraceae]] family,<ref>{{cite web|url=|title=''Lythraceae''|last=Carr|first=Gerald|publisher=University of Hawaii|accessdate=2008-12-20}}</ref>) a ''floral tube'' that can include the petals and the attachment point of the [[stamen]]s.
