Hermaphroditic

For a healthier water garden environment you can use oxygenating plants like Autumnal starwort (Callitriche hermaphroditica), Willow Moss (Fontinalis antipyretica), Water violet (H. palustris) and Elodea crispa (Lagarosiphon major).

The purple bud keeps getting smaller and the stem longer as the hands of hermaphroditic flowers and then of male flowers appear and bloom.

Polygamous plants bear staminate, pistillate, and hermaphroditic (bisexual - both sexes present and functional in the same flower) flowers on the same plant. An example is Acer rubrum (red maple).
