The Story
Plant Bio
Coreopsis tripteris is a tall, rhizomatous native perennial that brings a cloud of cheerful yellow, daisy-like flowers to the back of the border or meadow garden in late summer. This species is distinguished by its impressive height, reaching up to 8 feet, and its unique trifoliate leaves (divided into three leaflets). The foliage emits a pleasant anise-like fragrance when crushed.

Planting
How to Grow
- Select a site in full sun with average, well-drained soil
- Prepare the planting area by loosening the soil
- Dig a hole slightly larger than the plant's container
- Gently remove the plant and place it in the hole at soil level
- Backfill with soil and water thoroughly to settle
- Water periodically during the first year until established
Pro Tip
Pinch back the stems by about half in late spring to create a sturdier, more compact plant that is less likely to flop.

Care Guide
Do
- Provide full sun for the sturdiest stems and best flowering.
- Allow the soil to dry out between waterings once established.
- Leave seed heads for winter interest and to feed birds.
- Divide every few years to control its spread and rejuvenate the clump.
Don't
- Do not over-fertilize, as this can lead to weak, floppy growth.
- Avoid planting in consistently wet or poorly drained soils.
- Don't worry about pests; it's largely trouble-free.
- Do not plant in deep shade, which will cause it to stretch and flower poorly.

Common Questions
Tall Tickseed questions
What zones can Tall Tickseed grow in?
Tall Tickseed is hardy in USDA Zones 4–8. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.
Is Tall Tickseed deer resistant?
Yes — Tall Tickseed is rated deer-resistant. Deer typically pass it over, though extreme hunger can override any plant's defenses.
When does Tall Tickseed bloom?
Tall Tickseed typically blooms in mid-summer through early fall. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Tall Tickseed need full sun?
Tall Tickseed does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
Is Tall Tickseed drought tolerant?
Yes — once established (usually after the first full season), Tall Tickseed handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
