UPDATE-MARCH 2010- mine survived an unusually cold winter in zone 8a.

in may 2008 ,Researchers from the Floriculture Program at Michigan State University (MSU) evaluated and trialed coreopsis Limerock Dream . it performed very well in their greenhouse and garden trials . their conclusions were that it's hardy to zone 8a.

that's good enough for me, since they had nothing to gain monetarily.

i love the tiny ( maybe the size of a small woman's thumbnail) flowers and their staying power, even in our scorching heat and droughts and their awesome colors. a true standout in any garden, in my opinion.

UPDATE march 2010 - it has EMERGED ans survived our unusually cold winter here in zone 8 !!! it is on my ESE side of my deck. so a hip hip hooray from me...

I'm keeping my fingers crossed on this one. I was fooled once before by "Limerock Ruby" which was touted to be hardy to zone 6 but was not. This "Limerock Dream" is a beauty and has done so well since I planted it this past spring. This one too is supposed to be hardy, so we'll see. I read that it was originally bred in Rhode Island, so I'm hoping it likes it here in nearby SE Mass.

I had these last year and they were beautiful; sadly, they did not return this year at all. I'm in Zone 8 so I can only think this was due to the drought conditions we had most of 2007? Very dissappointing.

Previously i thought positive about this plant although i wasnt to fond of the flowers and the way the color quickly faded out to a brown. It returned one spring after being planted in late fall, but this year none of the 3 returned!! I have dug them up and checked the roots where there is no sign of life so im calling them dead! These definately are not hardy in zone 5b (the tag i have says hardy to zone 5).
I have read online many other people have not had luck with this supposidly hardy perrenial either. If you want a hardy tickseed try the yellow variety- they return faithfully year after year.

Editor's Note

While we can find several vendors stating the hardiness of this cultivar is zone 6-9, there have been numerous reports all over the internet of it not surviving. The patent states that the plant was observed tolerating -5 C. or 23 F. Therefore, we have changed the entry to reflect this.


This plant has been said to grow in the following regions:

Hesperia, California
Los Angeles, California
San Leandro, California
Winsted, Connecticut
Augusta, Georgia
Elizabeth City, North Carolina (2 reports)
Springfield, Ohio

Summerville, South Carolina
Garland, Texas
