Zigs very pretty flower . Mmm… It looks more like my calendulas that flourish in our colder temps. The leaves are a dead give away. Marigolds have fern type leaves . I grew calendula and they also tend to self seed , everywhere. My calendula thrived in our cooler weather and typically stoped or reduces blooms in our summer heat. It was a tricky bloomer as it sometimes seems to disappear and then return to blooming as weather cools in fall. By fall my marigolds droop and become covered in a heavy sludgy green goo.
