Ageratum (Ageratum) is a representative of the aster family. In nature, such a plant can be found in Central and North America, Eastern India. The name of such a flower is derived from the Latin word ageratos, which translates as "ageless". The fact is that cut adorable flowers can remain fresh for quite a long time. Since the 19th century, such a plant has become popular in European countries, and in Russia it is also called "long-flowered". This plant fell in love with gardeners for its spectacular fluffy flowers that look like pompons, which are part of very dense inflorescences. As a rule, they are colored in various shades of blue. Also, such a flower is very undemanding to care for. There are approximately 60 types of ageratum.

Features of ageratum

On a fairly compact bush there are bright green petiolate leaf plates in the shape of an oval, triangle or rhombus. Their edge is serrated. Leaves in the upper part are alternate, and in the lower and middle - opposite. There are many erect shoots, on the surface of which there is pubescence. Their height varies from 10 to 60 centimeters. Small bisexual fragrant flowers are part of not very large (diameter 1–1.5 cm) inflorescences shaped like baskets. And they are collected in complex corymbose inflorescences. They can be colored purple, pink, blue or white. The fruit is a 5-sided achene of a wedge-shaped elongated shape. 7 thousand seeds weigh only 1 g. Their good germination is maintained for 3-4 years.

In middle latitudes, ageratum is grown as an annual, because it is not frost-resistant. Such a plant will be able to decorate a rabatka, a flower bed, and will also look great in carpet compositions. Such a flower can be planted together with marigolds, calendula, snapdragons, which are also annual plants.

Features of growing ageratum from seeds


Most often, such a plant is grown from seeds. In this case, the boxes must be filled with a mixture that includes sand, humus and peat (1: 1: 1). Sprinkle the seeds with a thin layer of soil. The container is broken up with glass or film and removed into heat (at least 15 degrees). Crops need daily ventilation. The soil should be slightly moistened all the time. Therefore, it must be systematically moistened from a spray bottle. The first shoots will appear in about 14 days, after which the shelter should be removed.

Ageratum: growing and care


When the seedlings have a couple of real leaves, they need to be planted more spaciously. The pick is carried out 2 times. During the 2nd pick, the plant is planted in separate pots (cups). Ageratums need dry air and a constantly humidified substrate. Plants can only be watered in the morning. A couple of weeks before planting, the plant should be transferred to the street. If there is a threat of freezing, then the seedlings must be covered.


Landing in open ground should be done after the threat of night frost has passed. The selected area of ​​soil should not be exposed to drafts. The place must be sunny, because with a lack of light, the plants stretch out and bloom very poorly. A non-acidic, lightweight, well-drained soil rich in nutrients is best suited. However, this plant is not too demanding on the soil. In carefully loosened soil, you need to make not too deep pits, the distance between them is from 10 to 15 cm. You need to plant seedlings to the depth at which they grew in the container. Flowering begins after about 8 weeks.

Outdoor Ageratum Care

In order for the ageratum to please you with its unusually beautiful flowers, it needs to be properly cared for. So, this plant needs to be watered in a timely manner, remove weeds, loosen the soil, and also apply fertilizer to the soil. It needs a fairly abundant watering, but at the same time it is impossible to fill the flower in any case. After the plant is watered, it is necessary to loosen the soil and at the same time pull out all the weeds.

Top dressing is carried out with a frequency of 1 time in 2 or 3 weeks. Mineral or humic fertilizers are perfect for this. It is also recommended for feeding an infusion prepared on a mullein. But it should be borne in mind that fresh manure cannot be used to feed ageratum, because the plant reacts to it extremely negatively. Also, you should not overfeed the flower, because in this case the green mass will grow vigorously, but the flowering will become scarce. Do not forget to pick off fading inflorescences in a timely manner. This plant needs pruning for abundant and spectacular flowering. So, only a few internodes should remain on the shoot. After the pruning procedure, the plant begins to grow actively and bloom more abundantly.

What to do when the ageratum fades?

Before the first frosts begin, it is recommended to dig up the most lush bushes and plant them in separate flower pots. Plants can be placed in the house, on the veranda or on the balcony. Ageratums will bloom for the entire autumn period, and maybe even part of the winter. From these bushes in early spring, you can cut the cuttings and root them. Then, with the onset of heat, they are transplanted into open ground.

Such a plant is very fond of warmth, therefore, it is not able to overwinter even under cover under the condition of mild winter. In this regard, in the fall, it is necessary to remove the remnants of plants from the flower bed, and in the spring to plant new flowers there.

Pests and diseases

Ageratums are not resistant to diseases, which is considered their main drawback. Often rot appears on the root system of such a plant. If this happens, then it will no longer be possible to save the infected bushes. However, it should be borne in mind that the appearance of root rot can be prevented, and some fairly simple preventive measures will help you with this. So, the first step for planting is to choose a light, well-drained soil. Water the plant carefully, avoiding overflow. You also need to systematically loosen the soil. All this will help to avoid the appearance of rot on the roots. Ageratum is also prone to cucumber mosaic, as well as bacterial wilting, and such diseases develop due to violation of the rules of care.

Seedlings of ageratums, located in the house or in the greenhouse, must be protected from such pests as whiteflies and spider mites. If insects are found, the infected leaves must be torn off and treated with an insecticidal agent.

In the open field, nematodes and scoops can settle on this plant. Getting rid of such pests is not so easy, it is much easier to prevent their appearance. To do this, it is enough to provide the ageratum with proper care. Remember that only with prolonged violation of the rules for caring for such flowers, they become susceptible to various diseases and pests.

Is it possible to take seeds from verbena

Harvesting verbena seeds requires some skill and knowledge. After the buds wither, pods are formed. The color determines the readiness of the seeds inside. So that they do not spill out on the ground ahead of time, a nylon stocking or a bag of light fabric is put on the stems with seed pods and tied from below. After complete ripening, they are cut along with the shoots, the seeds are removed from the pods, laid out on a plate and dried for two weeks. Store the seed before planting and growing in paper bags in a cool, dry, dark place. Each must indicate the name of the variety and the date of collection.

Transplanting seedlings

To plant the ageratum on the site, you need to choose a site well-lit by the sun, protected from the wind. In the shade, the shoots of the plant will stretch out strongly, as a result of which, instead of compact densely leafy bushes, you will get naked, disheveled, weakly flowering branches. Ageratum is unpretentious to the soil, but prefers light drained slightly alkaline soils. If you dug up a plot in the fall, then before planting the seedlings, it is enough to intensively loosen the soil with a garden pitchfork. The further procedure is as follows:

  • At a distance of 15–20 cm from each other, holes are dug, their volume should correspond to the dimensions of the pots in which the seedlings grew.
  • Bushes, without destroying the old coma, are rolled into the holes.
  • The holes are covered with earth, the surface of the site is compacted and watered with warm water.

It is advisable to appoint the planting of seedlings for the evening or on a warm, cloudy day - in gentle conditions, the plants will recover from stress faster and grow. Ageratum grown through seedlings will come into bloom 50-60 days after the seedlings are moved to a permanent place.

Landing sites of ageratum

Ornamental culture is widely used for home and garden decoration. Most of all grows in a flower bed. When several varieties are planted, a beautiful flower meadow is obtained. The combination of plant varieties with red and yellow flowers of other cultures, elegantly and effectively decorates any flower bed. Also used for curbs and alpine slides.

To create expressive flower arrangements, ageratum is grown with other decorative flowers: zinnia, velvet, calendula and many others.

A light-loving plant requires a lot of sun and space. Planting in a shady place is not suitable for flowers, they stretch more in height, while losing their aesthetic appearance. For planting, choose a soil fertile and neutral in chemical composition. Rotted manure is used as fertilizer, which, unlike fresh manure, does not burn the roots of plants. Drainage is done on poorly ventilated soil to avoid rotting of the root system. For this, a layer of gravel is laid under the top layer of the earth.

The best varieties of ageratum are rightfully popular and in demand among many gardeners. An unpretentious plant, with timely planting and proper care, endows all its connoisseurs with an abundance of bright colors.
