The flowers on hostas are perfect flowers in
that they contain both the male (stamen) and female (pistil)
reproductive organs in the same structure. As with daylilies, the
flowers of hosta open for one day and then fade away. As mentioned
previously, the parts are all in multiples of 3. There are 6 tepals
(combined petals and sepals), 6 stamens, 3 cavities in the ovaries
and the stigma at the top of the pistil has 3 lobes. The flowers
open very early in the morning except for those related to the
H. clausa which do not open at all.
