Plant Type | Perennials Hardy |
Hardiness Zone | 3-9 |

Moisture | average, tolerates dryness |
Soil & Site | average to dry |
Flowers | The flowers are single, 2", light yellow and blooms almost continually. Starts mid to end of June through October (I have seen this plant blooming in early June and as late as early November, depending on the weather), blooms heavy during July to September |
Leaves | thin, thread-like leaves are palmately divided, stems become stiff and brown in the fall |
Dimensions | 18-24" tall, by up to 24-30" spread, size seems to vary with the site |
Maintenance | I have pruned this plant after it's first flush of flowers and it will quickly rejuvenate the foliage and reflower. I have also not pruned and it seems to do well. With out pruning the late season bloom isn't as heavy. This plant is hard to weed. It seems to catch any weed seed that blows past and they in turn germinate within the Coreopsis. These are removed by individually pulling and many times parts of the Coreopsis are pulled along with weed. |
Propagation | easy from division, cuttings |
Native Site | the species plant is native to eastern United States. |
Misc Facts | Named Perennial Plant of the year in 1995. Rated as one of the top ten perennials of all time. The genus name comes from the Greek words koris meaning bug and opsis meaning like in reference to the shape of the seed which resembles a bug or tick. |
Author's Notes | Coreopsis "Moonbeam” is one of the best perennials on the market, and I hate to be a pessimist about the plant, but weeding is a pain in the gluteus maximus. |
