Your Wildflower Meadow

Coreopsis brings us a summer of profuse blooms, often in sunny shades of yellow, and are low maintenance, disease-resistant, and bring delightful wildlife for our entertainment. ‘

The Special Charm of Coreopsis

A meadow of coreopsis

A memorable feature of Coreopsis is that the large and profuse blooms stand above the ground on thin, tall stems. In any breeze at all, the flowers appear to dance throughout the day. It is fun to watch a chubby bee land on blossom to take a little joy ride!

You do not need a big space, but if you like the naturalized, wildflower meadow look, somewhere in your garden this is a perfect plant. You will see blooms, heaviest early in the season, but offering flowers all summer.

Color

pink coreopsis

Historically known for brilliant yellows the plant hybridizers are producing a much wider range of colors for us to grow. Look for pinks, striped patterns, and brilliant ruby reds.

Leave the last few blossoms on the winter stems and be entertained by the birds who love the “tickseeds”. The seeds are small and loved by Goldfinch and other neighbors.

Coreopsis is a pollinator attractor. A three-year, Mid-Atlantic research study conducted at the Mt Cuba Center in Delaware found at least 29 species of pollinators visiting Coreopsis. Mt Cuba Coreopsis Pollinator study.

Their Name

The ancient Greeks called it Koris (bug) or Oris (looking like a bug) they were talking about the tiny seeds, and the birds were listening! We often use the name tickseed today.

Does Coreopsis Live Where You Do?

I find that the hardiness zone descriptions of Coreopsis are a little loose. I see ranges of zone 4-9 but many varieties are not suited to the northern end of those zones. If you have hot dry summers and cold winters this should be easy. The plant comes in 80 species. About 40 are native to North America and the rest are native to Central and South America.

Look specifically for varieties that grow with comfort in your zone. There are many plant growers and dealers who ship and specify their zones. If they do not, ask or use your local garden center or your county agricultural extension office. Both of these should have the very localized expertise that you require.

When To Plant Coreopsis

Plant coreopsis in early spring or early fall. I am writing this in early August and the large dealers are shipping now. Early fall planting should ensure you have root systems extending before the first frost and allow your plants to be well into growth mode in springtime. The plants are divided about every three years and this is normally done in spring.

How To Grow Coreopsis

Planting Coreopsis

Plant in a full sun location in which the soil is well-drained. Do not utilize waterlogged areas. Work organic matter into the first 6-8″ of soil. Sun and drainage are the operative issues for coreopsis. Sandy, rocky soil is not much of an issue. Give coreopsis what it really needs and it will shrug off the rest.

Trimming and Pruning

Deadhead the flowers to ensure robust blossoms. After the first spring blooms cut the plant back and a new flush of blooms will reappear. This is a plant in which it is not advisable to cut the stems to the ground as winter comes around. Leave the stems which will protect the plant over the winter. Leave, also, the last blossoms as their seeds will bring joy to the birds and therefore to you!

Other Maintenance

The coreopsis in the right location is a hardy, easy-care plant. If planting in spring add some fertilizer, probably not when planting in early fall, as cold weather is coming.

Summary,

If a naturalized area, especially one to attract wildlife, is what you want coreopsis will please.

Companion Plantings

The best companions for coreopsis are those which readily accept the same growing conditions and especially those which share its natural style of growth.

Some ideas to consider, depending on your location, are Russian Sage, Echinacea, helenium, and daylily. Add salvia to extend the color and height of your planting area.
