Lamiales
The lilac-pink flowers of the water mint attract butterflies and beetles.
In most species of the order Lamiales, the stamen filaments are united with the petals, a condition known as epipetaly. The degree of this union varies, ranging from a slight attachment to a fusion extending more than half the length of the stamen. Additionally, the stamens are positioned to alternate with the lobes of the corolla, meaning they are attached between the petals.1
