Chrysanthemum rubellum, the autumn daisy

No less than five varieties of Chrysanthemum had to be crossed to obtain Chrysanthemum × rubellum. Renamed the autumn daisy, this plant of the Asteraceae family offers colorful, long-lasting blooms.

How to recognize Chrysanthemum rubellum, the autumn daisy?

Chrysanthemum rubellum is a bushy, upright plant. It grows up to 120 centimetres high and 60 centimetres wide.

The woody stems are upright and branched at the base. They support deciduous foliage. The dark green leaves are toothed, but less so than those of garden Chrysanthemum (Chrysanthemum indicum).

The autumn daisy actually flowers from midsummer until the first frosts. At this time, it is adorned with corymbs of flowers, similar to large daisies. They hatch at the top of a long stalk. Their color depends on the variety. Chrysanthemum rubellum blooms in pink, white, yellow, salmon, orange or purple. Flowers can be plain or in several shades.

The plant is toxic to animals. Ingested, its leaves cause digestive problems. They can also cause dermatitis on contact with the skin. Keep your chrysanthemum out of reach of your dog or cat!

Our maintenance tips

Autumn daisies are hardy plants. Nevertheless, avoid wetting their foliage when watering them. This will reduce the development of diseases such as rust and powdery mildew.

Watering

Water when the substrate is dry on the surface, for about three centimeters. Use non-calcareous water, such as rainwater, filtered water or mineral water.

Don 't let water stagnate in the planter or saucer, as it may rot the roots.

Repotting

In spring, transfer your Chrysanthemum × rubellum to a larger pot, so that it can continue to grow.

Obtain a pierced pot suitable for the size of your Autumn daisy. Choose one deep enough (around 20 centimetres) for the roots to develop.

Line the bottom with a bed of clay balls to promote drainage, then add a layer of potting soil for flowering plants. Plant your Autumn daisy, the root ball should be a few centimetres below the edge of the pot. Fill in with substrate.

Water generously to remove air bubbles and help the plant take root.

Fertilization

You can stimulate the growth of your plant during its growth phase, in spring and summer, with fertilizer.

Autumn daisies are greedy plants. Feed them with a flowering plant fertilizer to support their growth.

Prune

Using clean, sharp pruning shears, cut back the clumps to within ten centimetres of the ground.

Plantation

Once the last spring frosts have passed, you can plant.

Basin your Autumn daisy to rehydrate it.

Choose a sunny spot and dig a hole slightly larger than the root ball. If you're planting several specimens, space them at least 50 centimetres apart. Remove any stones, weeds or other branches that might hinder root development. Place a little compost at the bottom of the hole.

Plant your plant. The top of the rootball should be level with the ground. Fill in with garden soil. If your soil is heavy, add a little sand to lighten it and improve drainage.

You can mulch the base with a mineral material to keep it warm in winter and cool in summer. Water generously to encourage rooting.

Cutting

Take your Autumn daisy out of the ground and determine the number of plants to be separated. You candivide them by hand. If the roots are too intertwined, cut them with a sharp, disinfected knife.

Transplant or repot.
