Coreopsis Mercury Rising – REPEAT Blooms from Summer-Frost

Coreopsis Mercury Rising

Mercury Rising is both Heat & Drought Proof with stunning red blooms!

Coreopsis Mercury Rising is one of the most colorful, drought proof perennial ground cover for sunny areas and a personal favorite new plant introduction for 2012.

Finally, a velvety-red flowering HARDY Coreopsis ((PPAF)that blooms for 5+ months, takes on the heat & humidity and is bone hardy to zone 5,  This year our record breaking heat & humidity has not deterred the performance of this stunning, hard working garden plant in my Michigan  garden.

This breakthrough new hybrid is the result of many years of hand-crossing by famed hybridizer Darrell Probst.

Darrell has spent the past ten years striving for a Zone 5 (possibly Zone 4) ultra-hardy bright red-flowered Coreopsis to add to his much-acclaimed Big Bang Coreopsis series. He has hit it out of the park with his new velvety-red Mercury Rising Coreopsis!

Breeder Comments

“From what I have seen, there are no other Coreopsis in the market place that combine short, compact habit and large flowers with striking colors in a zone 5 hardy, true perennial”  stated Darrell.

“Plants are sterile, so no deadheading is needed to keep them in bloom. Plants blooms from early May in the south, early June in the north until autumn frost, producing more and more flowers as the season progresses.”

Prolific in containers as well!

“My Big Bang breeding program (which includes Full Moon, Red Shift, & Cosmic Eye) is from 100% perennial species, no annual species are in their blood and tested as far as Georgia with good results.”

Foliage is a bright, healthy green all season and shows NO hint of the dreaded mildew disease that often affects other Coreopsis.

Combine Mercury Rising with Cosmic Eye Coreopsis for a color echo effect


I combined Mercury Rising with  Nepeta Walker’s Low and love how it looks together. Other combination possibilities: Festuca Boulder Blue, Coneflowers, Sedum Angelina , Rudbeckia GoldsturmYellow Knock Out Roses, or  Cosmic Eye Coreopsis Use in groupings of 7 or more for best effect.

Coreopsis Mercury Rising is a powerful color that looks dynamite in the sun perennial garden. As the season wanes the flowers just keep getting bigger.  Late in the season  flowers take on a cream streak.

You’ll want to add this remarkable perennial to your garden so you can start to enjoy the many features and rewards this Coreopsis offers!
