Rug Aster Snowflurry - Planting, caring and cutting

The carpet-aster 'Snowflurry' (Aster pansus 'Snowflurry') is a pretty herbaceous shrub that is reminiscent of small snowflakes with its characteristic flowers - even in autumn. From this optics derives also the English name as snowflake. This aster species is also the only one of the asters that is characterized by a ground covering growth. Again and again, new shoots of the carpet aster form, which ensure that the plant spreads like a fan. Over time, a dense stock that resembles a carpet forms, which also explains this name of the plant.

Even though the white plant is not native to Germany, it does itself very well in a rock garden. However, the carpet aster flowers only in September and October, where it barely exceeds a stature height of ten to 25 centimeters. Due to the fact that the carpet aster does not bloom before September, it is also referred to as September herb. In the vernacular, the perennial plant is also known as Herbstaster. Nevertheless, this aster species is not widespread in this country so far.

The charming look of the carpet aster

The carpet aster has countless star flowers of fine-beamed nature. Especially in autumn, the dense flowering is a true feast for the senses. The cute white cup flowers are characterized by a yellow center and tiny size. Compared to the linear leaves in a dark, rich green, the flowers of the carpet aster form thus a successful contrast. At the upper end, the stems of the plant are quite branched. In the garden, the carpet asters are particularly good if they are planted as follows:

  • growing down on walls
  • hanging on stairs
  • in stone beds
  • as a container plant
  • in troughs or boxes as ornamental plant


  • on a bee pasture
  • on a butterfly pasture
  • on an insects pasture

Incidentally, the carpet-Aster tolerates very well with many planting partners, which can come, for example, from the family of the asters. Therefore, the carpet aster in his own garden can be combined, among other things, as follows for a colorful color spectacle:

  • with high aster varieties that bloom bright blue
  • with feather grass
  • with violet verbs
  • with Indian grass
  • together with the bluish milkweed
  • with the big fat leaf

Basic information on the plant genus of asters

As a soil-scented plant, the carpet aster is a real exception in the aster family. However, it also has many features in common with other aster species. This plant genus belongs to the daisy family, of which around 180 different species are known around the world. Especially in Eurasia, asters are widespread. Many aster species are used in gardens and parks as ornamental plants.

Most asters, like the carpet aster too, are perennial. However, there are also annual and biennial plants of this genus. Regarding their stature heights, the plants differ greatly. These can amount to just three centimeters to three feet. Also at the leaf margins a variation from serrated to smooth is observed. The following color spectrum covers this plant family:

  • White
  • pink
  • blue
  • purple
  • red

The genus as such was already documented in 1753. This goes to the cap of Carl von Linné. The genus name "Aster" derives from the Latin of "astrum", which means something like star or star and thus indicates the flower form of most asters. Each aster species is also known under its own Latin name, which is for the carpet or snowflurry aster, for example, "Aster pansus".

These locations prefers the carpet aster

The carpet aster can be planted both on stone and open spaces as well as on the woody edge. In addition to a full sun, the Aster is above all a dryer, but sufficiently permeable and nutrient-poor soil very important. On open spaces, the Snowflurry Aster thrives very well even on moderately dry to fresh soil. At the edge of the wood, especially a sunny and sufficiently warm location is very important. If the carpet aster has a sufficiently strong root ball that has burrowed deep enough into the soil, it can even thrive in a partially shady spot.

Plant the carpet aster in your own garden

If you want to plant the carpet aster in your own garden, you should keep a planting distance of at least 40 centimeters. The ideal planting period extends from March to October, so that the small snowflake plants can be planted in their own garden for most of the year without any problems.It is best to plant the carpet aster in a composite consisting of three to five individual plants.

Tips for successfully creating a perennial bed

If the carpet aster is to be successfully integrated into a perennial bed in your own garden, all home gardeners should take a few important expert tips to heart. After the plants have been unpacked, it makes sense to first put them in a water bath for ten minutes. The root ball of the carpet aster should be able to saturate sufficiently with water, so that the plant can grow as well as possible. This can be seen from the fact that in the water at some point no further air bubbles will rise, which is to be regarded as a clear indication of a saturated root ball.

If a large bed is to be created, it makes sense to place the individual plants in their pots at the correct distance along the bed. Thus, the required planting distance distributed over the entire area can be determined correctly. Any corrections in the distances between the carpet aster and the other plants are thus also much easier possible. Not only the carpet aster, but also all other plants are placed in a perennial bed best as a group of three or five. This ensures a particularly beautiful appearance.

The carpet asters and other plants should be carefully removed from their pot without damaging the roots when removing the plastic pot. Therefore, under no circumstances should be pulled on the shoots of the plants. Rather, the pot should be gently placed on his head in order to remove the carpet asters and other plants particularly easily. These should of course be collected as gently as possible with the still free hand. Now the plants can be placed in a sufficiently large planting hole. Then apply the carpet asters and other plants weather-oriented in the evening or morning hours, to facilitate their growth in this way also noticeably.

Maintain and trim carpet aster correctly

Carpet aster snowflurry flowers

To maintain the carpet aster a pruning is recommended in the spring. This should absolutely be carried out close to the ground, and only when the main flowering has already taken place. Even if the carpet aster does not let itself be carried away to a second bloom, the pruning contributes to the fact that a healthy, splendid new shoot of the plant can take place. Since the carpet aster tends to Selbstaussaat, this can also be kept under control by the pruning.

The water requirement of the plant is also rather low, which is why this Aster variety is so well suited for rockeries. Therefore, the carpet aster must be watered only very rarely and only in really dry weather conditions that last for an extended period of time. If the irrigation of the carpet aster is required, this is easily recognized by the flabby foliage of the plant.

Even if the carpet aster should be poured only rarely, a thorough casting, which penetrates the plant completely, if necessary to recommend. However, under full sun, the perennial plant should not be watered under any circumstances. Rather, the plant gets better if it is poured in the early morning or in the evening, when the sun has already set.

Those who regularly split the plant every two to three years have the opportunity to easily remove all weak shoots and roots. This contributes to a better growth of the carpet aster, which also results in a radiant flower power. Through this targeted step, the roots of the plant are stimulated to spread to the deeper layers of the earth. This in turn helps to ensure that the carpet aster can compensate for possible dry periods better on their own.

Apply carpet aster

To fertilize the plant, a manure fertilizer, which is known for its long-lasting effect, offers. This is available from specialist retailers, with a fertilizer that can be used in a concentration of 40 to 50 grams per square meter is the ideal choice. After all, the carpet aster is only once a year and to fertilize best in the spring. So the bloom growth can be promoted specifically in the autumn. Not only organic, but if necessary also mineral fertilizer can be used to fertilize the carpet aster.

Keep the carpet aster in the winter

The carpet aster is a frost hardy variety. Accordingly, no special winter protection is required so that the carpet aster can shine again in full glory next autumn. The perennial and very easy-care plant can thus give all hobby gardeners a lot of pleasure for a long time - and without any major effort on their part. After all, the carpet aster even at temperatures of up to minus 23 degrees Celsius is considered absolutely frost hardy.

Disease Pests on the carpet aster recognize and fight

The so-called astery wilt is a problem that affects almost all asters. This also applies to the carpet aster. This disease causes the foliage of the plant to turn brown.If an infestation is found, the asters must unfortunately be planted out of the garden bed, so that the aster sprout does not pass on to other plants.

If the weather fails, infestation with mildew is also possible, for which carpet asters are quite vulnerable. However, you can provide it with a special tea made from the field horsetail. The carpet aster should be sprayed so that the mildew does not stand a chance. After all, this tea contains enough silica so that the damaged fungus can not sit down on the carpet aster. In addition, most gardeners have special fungicides on offer to fight mildew.

As already mentioned, all hobby gardeners can also contribute to the lasting health of their carpet asters by another measure. For this purpose, it makes sense if the root ball over the multi-year life of the plant is divided again and again planted in another place. This strengthens the roots and thus the resilience of the carpet aster enormously.
