The girl's eye as a garden shrub: hardy or not?

The girl's eye as a garden shrub: hardy or not?

The wintering of girls' eyes in the open air

Even short-lived subspecies of the genus Coreopsis can sometimes be stimulated to sprout again in spring in mild locations such as in the wine-growing climate if their herb is cut back to just above the ground immediately after the flowering period. Longer-lived varieties can be overwintered directly in the bed, but sometimes only tolerate minus degrees in the range of -12 to -20 degrees Celsius. Therefore, after pruning in autumn, you should be covered with a protective layer, which can be made of the following materials:

  • leaves
  • piled earth
  • Bark mulch
  • Pine needles

  • Column fruit - hardy or not?
  • Eustoma or prairie gentian is not hardy
  • Woodruff - hardy or not

However, some gardeners also prefer pruning in spring and leaving the withered leaves to stand over the roots of the plants as a protective layer over the winter.

The wintering of the beautiful faces in the pot

When overwintering outdoors, all potted plants are usually exposed to even colder temperatures, as the insulating effect of the soil substrate can only have a limited effect. Therefore, girls' eyes in the pot should not only be covered with leaves or another layer of mulch, but if possible also wrapped with a protective fleece and placed in a south-facing position next to a house wall. In addition, a styrofoam plate placed between the floor and the planter (€ 25.90 at Amazon *) protects against the cold attacking from below.

Water hibernating plants sufficiently

It is important for both outdoor and pot specimens of the girl's eye to ensure an adequate water supply in addition to temperature protection in winter. Therefore, you should water the plants moderately in winters with clear frosts on frost-free days. After all, drought damage poses a far greater threat to many plant species in winter than actual freezing of the plants. In this respect, too, a layer of mulch over the bed proves to be practical, as the soil dries out less in winter due to wind and sun.


Even perennial and hardy types of the girl's eye do not have an open lifespan, but can age after four or five years. To prevent this, it is advisable to carefully dig up long-lived varieties after about three years in the same location and to multiply them by division.
