Butterfly Mistflower (Chromolaena odorata )
Other common names for this plant include
Blue mistflower, Jack in the bush, Fragrant boneset, Fragrant mistflower, Crucita, Christmas Bush, Siamweed
Butterfly mistflower is a particularly important nectar source in Texas as its bloom period 
overlaps with the time of year during which butterfly populations are at their peak. Its purple-blue flowers are produced in abundance at a time when Monarchs are migrating and fall rains are producing habitat that supports large populations of butterflies.
This tender subtropical perennial is evergreen only in the far southern portion of Texas. Further north it freezes to the ground but will develop new growth when favorable weather returns. It also spreads by seed. Interestingly, this plant has been introduced and naturalized outside of its native range to parts of Africa and Asia where
it has become a highly invasive weed. In the United States, it is listed as a noxious weed in Hawaii.
Importance as a caterpillar food source: Butterfly mistflower is not a caterpillar food source.
Importance as a butterfly nectar source: Each plant produces a large number of blooms providing an abundant amount of nectar that is attractive to many different species of butterflies. Monarchs and Queens are particularly attracted to butterfly mistflower.
