Coreopsis
Coreopsis verticillata
Family Asteraceae

Threadleaf coreopsis holds a golden haze over ferny foliage for three months on poor soil, drought, and outright neglect — the closest thing perennial beds have to a no-input flower. A native, at that, blooming summer into fall when borders start running out of ideas.
Front-of-border sized at one to two feet and hardy zones 3 through 9, it thrives on dry slopes and hot banks the hose never reaches, with bees in steady attendance. Winter-wet feet are its only enemy. Line a dry edge with it and cross that bed off the worry list.

What each band means
- Bloom — flowers open — pollinators working, frost on blossoms is the danger.
- Prune — shape it now — cuts heal cleanly and structure is visible.
These are the species' typical months — expect them a few weeks earlier in warm zones and later in cold ones. Watch the plant, not just the calendar.

Questions
Coreopsis questions, answered straight.
Is coreopsis safe for kids and pets?
Coreopsis is commonly eaten and isn't considered toxic, but "commonly eaten" isn't a guarantee for any particular person or animal — allergies, quantity, and which part you eat all matter. Never eat a plant you haven't positively identified, and check with a vet before letting pets or livestock graze anything new.
How do you propagate coreopsis?
Division or seed.
