Tips For Growing Coreopsis (Tickseed)
Coreopsis (Tickseed) are long-blooming native wildflowers that are easy-to-grow and provide ample nectar for butterflies. They're resistant to browsing rabbits and deer. Coreopsis can be divided into two groups that have different growing requirements: Coreopsis grandiflora and Coreopsis verticiliata (Threadleaf Tickseed) cultivars and hybrids.
1. Coreopsis grandiflora types (Tickseed) - these cultivars are generally grown from seed and are a short-lived perennial (3 to 4 years).
Preferred growing conditions:
- Needs sandy/gravely and sandy loam type soils. Avoid clay.
- Does best with gravel mulches.
- After their second growing season, only requires deep but infrequent watering. Too much water makes them floppy and shortens their lifespan.
- Plant in full hot sun.
- Adding just a few handfuls of compost and Yum Yum Mix in the planting hole is enough. Don't plant into a rich, highly-amended soil.
Special comments
- Deadhead plants to prolong bloom. Leave a few seed pods on the plants to encourage re-seeding.
2. Coreopsis verticillata (Threadleaf tickseed) and hybrids - These are long-lived perennials that spread by rhizomes to form wide, dense growing clumps.
Preferred growing conditions:
- These species grow in a wide range of soil types including clay. Avoid very alkaline soils as they may get chlorotic (yellow foliage) due to unavailability of iron and other trace minerals.
- These plants don't need mulching except in hot climates.
- These are moisture-loving perennials and do best in moderately moist soil conditions.
- Plant in full sun areas.
- They like compost-enriched soils at planting time.
Special comments
Threadleaf tickseed plants are often late to wake in spring from dormancy, so don't worry when other neighboring perennials wake up first.
Garden care for all types of Coreopsis:
- Fertilize Coreopsis just once in fall with Yum Yum Mix and Planters II. In addition, for C. verticillata types, green sand is recommended for alkaline soils to correct or prevent chlorosis.
- Plants can be divided in mid-spring when clumps die-out in the center or become too large for their place in the garden.
- Leave all Coreopsis varieties standing over the winter and cut back to 1-2" inches above the soil in mid-spring when the plants begin to wake up.

These are placed in various spots in my garden and help,bring out colors of the other plants as well as stand out on their own. Delicate yet noticeable on their own with all the blooms. Constantly blooming all summer long.

I bought two of these. I planted them in early spring, and by mid-summer they were gorgeous. They ever turned pink though...they were yellow with dark middles. One died that fall. It went from gorgeous to dead. I think it may have drowned... The second one started coming up this spring, but just looked weak a puny. We got a late freeze, and that ended it. Guess it wasn't meant to be. I have very heavy clay soil, which I amended with composted horse manure. Most of my plants do great in it, but these guys didn't seem to appreciate it. I think they may be happier in something fluffier. Even though they didn't work for me, I'd still recommend trying them. They were gorgeous and full while in bloom. I just think they didn't like my soil.

I planted this plant in one of my larger flowerbeds as an experiment to see if it will come back the next year - I will have to wait until spring to find out. If it survives, I would like to plant several more.

Wow I planted this in the spring and by mid summer it was huge with lots of flowers! It looked like it was 3 plants instead of just one. Pretty.

Really liked the catalog description; but this first year it was pretty small and didn't flower much or for very long. I'm waiting, hopefully, to see how it does in a second year.

Q & A
Suggested Companion Plants:
USDA Hardiness Planting Zones
To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.
- If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
- If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
