Plant of the Month: Mist Flower – A Butterfly Favorite

October 9, 2019

If you want to attract butterflies to your yard, be sure to plant Mist Flower (Conoclinium dissectum, also sold as Eupatorium greggii). This flowering perennial can grow to a height of 1 ½ – 2 ½ feet and a width of 2-3 feet. Beautiful fuzzy lavender-blue, and blue-purple flowers adorn the plants in tight clusters at the ends of branches, and attract butterflies, especially the Queen Butterfly, Danaus gilippus.


Mist Flower, (also called Blue Mistflower) is found along stream beds and on mesas and flats from western Texas to southeastern Arizona, south into northern Mexico. Plants are frequently found on sandy soil, loam or limestone-derived soil between 3,500- and 6,000-feet elevation.

Blue Mist’s lacy green foliage is attractive when planted in mass under the filtered shade of desert trees.


This small herbaceous perennial can be upright and bushy or have stems sprawling along the ground and then turning up near the ends. Its light green, pinnately lobed leaves give it a fine texture. Flowering may begin as early as March and can continue until October or November.


Plants are root-hardy to at least zero degrees Fahrenheit, with the tops freezing back when nighttime temperatures drop into the low 20s F. They will appreciate midday filtered light in the hot, interior desert regions but will grow fine in full sun if given supplemental water regularly in the summer. Plants are low – to moderate water using and grow fine in loose, rocky, native soils, reaching two feet tall and two feet wide in a couple of years. Cut back any dead stems in late winter, and if the plants overwinter without dying back, cut them to ground level, as they will resprout from underground stems called rhizomes.

The Queen Butterfly (seen here and in the upper right photo) is a frequent visitor to this flower. They are also visited by a close relative, the similar-looking Monarch Butterfly.



Mist Flower is very easily distinguished from any other Eupatorium species by its combination of highly divided leaves and lavender-blue flowers. The flowers are very similar to those of Ageratum corymbosum, but the divided leaves of Conoclinium, or Eupatorium readily separate the two plants.

The Mist Flower provides a crucial source of nectar. Learn more about why male butterflies are particularly attracted to this flower. It’s fascinating!


This plant is the perfect size to use in a cactus and succulent garden or to plant near large boulders. Match it up with Agave species, Dasylirion species, Echinocactus grusonii, Ferocactus pilosus, Hesperaloe funifera, Nolina nelsonii, and with tall accents like Yucca rigida and Yucca rostrata. Get into the butterfly garden with Ageratum corymbosum, Lantana ‘New Gold,’ and Salvia greggii.


Rabbits will likely eat the stems if there is nothing else around. Best flower production takes full sun, which needs more watering during the hottest time of the year.
