Will Astrantia Spread?

Astrantias grow in groups of 18-24 inches (45-60 centimeters) in a clump of deeply divided leaves. They then spread by stolons. However, don’t spread very far. They are well-known for self-seeding, which means they can grow new plants. Each leaf has three to seven lobes, and they are palmate in shape. They also toothed edges that measure 3-6 inches long. The few leaves on the branches of the flower stems are narrow and only have three lobes. The medium green foliage looks good all year, but it doesn’t have a lot of exciting fall colors.

They have a neat growth habit. Freshly sown seeds are easy to grow. They take little time or effort to take root. It is best to remove deadheads to extend the flowering period and prevent the plants from self-seeding. However, astrantias can easily be contained. Dividing clumps aids in the preservation of vitality.

Care Tips

This is what you should do to ensure that your Astrantia plant remains in good health:


It’s important to plant Astrantia in suitable soil because it will grow better there. Plants need good soil before they can grow well. This flower likes slightly acidic soil, but it can grow in heavy clay soils. Loamy and light-rich soil is ideal. Moisture should be kept in, but water should be able to drain away from it. You can add compost, dried leaves, or coffee grounds to the soil to make it better. Adding acid to the soil will help the plant grow.

Light or sandy soils won’t be able to hold enough water for these plants. Since clay soils don’t dry out in the hot weather, you can use them.

Keep the crown of the Astrantia plant about 1/2 to 1 inch below the surface of the soil when you plant it. Check to see that the roots are spreading out and down. Make sure you don’t pack it too tightly. Fill in with some loose soil, but don’t make the soil dense. You can add mulch to help keep water in even more.


The plants can grow in different types of lighting. Astrantia can grow in full sun. This is the best place to put the plant. It should get some morning light, but it should be in an area that receives some shade all day. It is ideal for planting it in partial sun to dappled shade so that it can grow well. Places where trees or shrubs grow are good. They should be in a moist area.

Hadspen Blood, a dark variety of Astrantia, grows better in areas that get a lot of sunlight. It is important to check the growing conditions for any variety you want to use.

Astrantia plants can be mixed with many other plants.


You should water your Astrantia every few days and thoroughly. This will help keep soil moisture even. Keep in mind that this plant can’t stay dry for long periods.


Make sure to keep your Astrantia plants cut back regularly. If you don’t want them to spread, you’ll have to cut them back. This will make them more likely to flower. This also means that you can take a few flowers off before they are done blooming, and you can have a beautiful flower display.
