    Maintenance Notes: 

    This easy to care for annual loves heat and flourishes in difficult conditions. The tall plants have deep green, glossy foliage and flower most heavily when temperatures are hottest. While it will bloom in late summer in Midwestern gardens, it will bloom earlier in hotter climates and is a great plant for Southern gardens.

    It does not spread from underground rhizomes.

    Not a heavy feeder and deadheading is not necessary.

    • These were in my garden when I bought my house four years ago. I’m in zone 7b, but this plant was invasive, spreading several feet in all directions from a single plant. The lush, dense thicket of plants was five feet tall. A year after trying to remove it, I’m still fighting volunteers; it resprouts from the smallest node fragment. That said, pollinators love it, deer don’t bother it, and it’s beautiful. I’m allowing brave pioneers to grow in my now-diverse pollinator garden, and I will enjoy the ones braving my shade garden at woods’ edge across the yard. I first noticed this plant when I lived In Florida, where I guess it was manicured into polite behavior. Now I know it better; nice to know some living creature likes our increasingly hot climate of Piedmont NC.

    • I bought these at my local garden center, on the container it says it’s a perrineal, I sure hope that’s right. Anyways I love the purple blooms, very plentiful. Will definitely buy more!

    • They have a lovely structure and great leaf color... BUT barely any blooms. Out of the 5 plants we have planted they probably average a few blooms total per week by late August in zone 5b. Nice looking plant, but would only plant again for leaves and structure, not blooms.
