PlantFiles: Bigflower Coreopsis, Largeflowered Tickseed, Tickseed Coreopsis
Coreopsis grandiflora 'Early Sunrise'

Despite being hardy to Z4a, this did not survive this past winter in my perennial bed. It did survive in another place on my property, however, in a different aspect.

My husband bought 2 Bigflower Coreopsis, Largeflowered Tickseed, Tickseed Coreopsis 'Early Sunrise' (Coreopsis grandiflora) plants in 6 inch pots for 25 cents each on the dying plant table at Walmart last year. With a little care they came back to life and flourished. One was planted in a large container that is sunken in 15 inches of mulch in a flowerbed right by the street and is in the hottest area of my yard. The other one is in full sun in the ground in another flowerbed that receives a lot of heat. Both survived the winter and are flourishing. This is a really great Coreopsis that blooms profusely and requires little care once established. The bright colored, large blooms are beautiful against the deep green foliage.

I may be the only person in Houston who can't grow these! I planted several 4" nursery pots in a raised bed of amended, well draining soil in early June. They put out a few blooms and then promptly got some kind of fungal disease. All the leaves turned gray and shriveled. I cut them back and sprayed, but they didn't improve, so I pulled them up. No more of these for me!

I love this plant! It was handicapped by some stem burrowing bug last year but it has came back beautifully this year. Mine is about a foot and a half across. It just keeps on blooming as long as you deadhead. I have had a few volunteer plants in my driveway which I give to friends!

Will bloom repeatedly when deadheaded! My information says it is hardy in zones 3-11. Light aids germination of seeds.

I love this plant, but I know very little about it...So far I have one that I purchased about six weeks ago...It is blooming profusely....I deadhead the plant and new buds just keep coming.... I am happy to hear it will continue to bloom until October...Yeah..... that is the kind of plants I want in my garden......lots of beauty for all my work... I love to save seeds and propagate...It just gets too dry here in May. Hopefully it will be like the last couple years and some rain will come with the change of the month. I want plants that bloom more than two weeks......I am new to gardening and and learning rapidly thanks to this site.

I have never had this plant, but I did some seeds in Winter sow and they are growing. It sounds like a good plant,easy to grow so I am looking forward to having it in my flower beds.

Grows readily from seed I threw a couple of spent dried flowers into another flowerbed last autumn, and I have a nice sized plant in 2005.

Propagates nicely when small pieces are seperated from the original plant, also I split a few off in the early spring before it started to flower. They are doing great in pots and in another new location.

This is a fabulous plant, I plan to get a few other varieties in the coming years.

A very clear gold/yellow

flowers last well in when cut.

Large golden-yellow blooms flower from June to September. Prefers a rich, moist soil. Attractive to butterflies, too. Beautiful coreopsis!

A very strong, rich and long blooming compact (30-45 cm)perennial. She blooms in her first year after sowing with 5 cm half filled golden yellow flowers. She keeps on flowering into october if you deadhead. I love her very much and I consider her a must in any merry garden. She gives good cut flowers also.
