Iberis has a taproot system and therefore reacts very badly to transplanting. Depending on the species, the shoots can be upright or tapering. The simple little leaves are usually a dark green with a tint. Its inflorescences are umbrella-shaped and contain small flowers a centimeter in diameter.

Iberis blooms very lushly, and often there are so many flowers that they cover all the leaves. Flowers can be pink, purple, white, lilac or red. Flowering begins in May or August and lasts for about eight weeks. Often perennials bloom a little shorter than annuals. Almost all species have rather fragrant flowers.

The fruit is a bicuspid pod that is oval or circular in shape, slightly flattened and hollow at the top. The seeds remain germinating for 2-4 years.

Growing Iberis from seed

Growing this flower is possible from seed as well as by vegetative propagation. Seeds are the most popular propagation method because they can easily be bought in a store or collected. Most varieties of this plant are sown directly into the open soil in April.

To make the flowering last even longer, the seeds should be sown twice with a distance of 15-20 days. The first seedlings will appear after 7-14 days. Sprouts need to be thinned, and the distance between bushes should be 12 to 15 centimeters. Winter sowing can also be used.


Loss-free sowing!

Sowing in seedlings

Sowing seeds in seedlings should be done in early spring and the soil should be loose. The seeds should be placed in the ground only 1 mm and covered with a thin layer of river sand. The container must be covered with glass, because the humidity of the air and the substrate must be moderate all the time. The container should be moved to a well-lit and warm place. Water the seedlings only if necessary, and you must always use a sprayer.

Sprouting is not recommended.

Transplanting into the open soil

Time to transplant

Transplant the plants into the open soil in spring when there is no risk of frost. This is usually in May. Iberis should be planted in a well-lit area with loamy, sandy or stony soil. Remember that a stagnant fluid in the root system is very bad for the plant.

How to plant

Firstly very carefully remove the seedlings from the container, taking care not to damage the roots. Take the plants together with a root ball. The distance between the bushes should be 12 to 15 centimeters. The soil around the plant after planting should be tamped, then the bushes should be watered. If you plant different types of Iberis, make sure to plant them at a very large distance from each other as they are subjected to pollination.

Iberis can also be propagated by splitting the plant and by cuttings.

Suitable care

Growing Iberis is quite easy and even inexperienced gardeners can handle it. Watering should only be done during dry spells. Such flowers can do without fertilizer, but for even more lush flowering, Iberis can be given 1 or 2 feedings per season with multi-nutrient fertilizer. For the plant to grow and develop normally, it needs to remove fading flowers in time.

When the plants have finished flowering, they should be shortened by 1/3 of the shoots, in this case the bushes will look very neat. A perennial plant that is 5 years old should be pruned, otherwise the flowers will become shallow and the bush will become less showy.

Diseases and pests

Pests on such flowers may include cabbage aphids, mealybugs and earthworms. To make the fleas, which eat holes in the leaf plates, go away, it is recommended to moisten the soil near the bush. To get rid of aphids, you will need to treat the infested flower with a solution of liquid potassium soap (150-200 g of the substance per half a bucket of water).

If necessary, the treatment can be repeated after 7 days. To get rid of mealybugs, you will need to treat bushes with mospilan, actar or fytoverm. At the same time, such a treatment will need to be carried out one more time in 7-15 days after the first one.

The root system of such a plant is susceptible to fungal diseases. For preventive purposes, before planting such a flower, it is necessary to water the area with a fungicidal agent.

In case the roots begin to rot, the infected specimens should be dug out and burned, and the place where they grew should be disinfected. Such a flower is very resistant to other diseases. If it is watered according to all the rules, fungal disease will not be a problem for Iberis.

After flowering

Seed collection

Seeds appear where the flowers were. Since the blossoms last quite a long time about the ripening of the seeds takes place all the time.

So you can collect seeds at any time as soon as they are ripe. To do this, you need to cut off the pods and dry them, placing them in a warm place. The seeds extracted from such pods should be stored in a place where it is dry and cool, until the planting. No seeds can be collected, as Iberis propagates itself perfectly. In the spring you will see well-timed shoots that will need to be thinned.

Wintering perennials

Even though this flower is rather frost-resistant, it is still recommended to cover it up and lapniks are perfect for this. The parts of the bush that are above the ground will first need to be cut away.
