Calotropis gigantea (Crown flower) is a species of Calotropis native to Indonesia, Malaysia, Philippines, Thailand, Sri Lanka, India and China.
The clusters of waxy flowers are white or lavender, and have a little "crown" in the center composed of five downward-pointing, twisted petals that resemble an elegant miniature royal crown. They are produced in bunches among the leaves, which are light green and fuzzy on both sides, growing on succulent milky stems. When fully grown, each small tree or large bush can support hundreds of Monarch butterflies as the adults sip nectar from the flowers and the caterpillars eat the leaves. Don't worry about the caterpillars, as the plant will quickly regrow whatever they eat and more,
