Here are the main things you need to provide to your Astrantia plant:


Astrantia prefers slightly acidic soil, although it can grow in heavy clay soils. Ideally, the soil should be loamy and light rich. It should retain moisture but also drain off standing water. You can add more organic materials such as compost, dried leaves or coffee grounds to improve the soil. One advantage of coffee grounds is to add acidity to the soil, which will make the plant thrive.

When planting Astrantia, make sure to place the crown of the plant 1/2 to 1 inch below the surface of the soil, and spread the roots out and down. Carefully, fill in with loose soil but necer pack it too tightly. You can add mulch to retain moisture even more.


Astrantia plants are adaptable to different lighting conditions. They can grow well in the full sun. Ideally, you should keep it somewhere where it can receive a few hours of morning light but dappled shade through the rest of the day. It is best to plant it in partial sun to dappled shade to make it thrive. Keep in mind that these plants prefer dappled shade. Good spots are under the trees or around shrubs, in a moist border.


You should water your Astrantia regularly and thoroughly. This will help retaining even soil moisture. Keep in mind that this plant cannot survive sustained periods of dry soil.

Additional Tips

  • Some darker varieties of Astrantia, such as Hadspen Blood variety, grow better in sunnier spots, so it is important to always check what the growing conditions are for any specific variety that you wish to use.
  • Astrantia plants can easily be combined with many different plants. The most effective include: Gillenia trifoliata, Persicaria amplexicaulis, Geums, Dryopteris, Thalictrums, Lysimachia atropurpurea, Melica altissima, Salvias and Sambucus nigra.
