Heiranthus (Lacphiolus): Planting And Care In The Open Field, Growing From Seed

The flowering herbaceous plant Cheiranthus can be an annual, biennial or perennial and belongs to the Cruciferous family. It is also called jaundice, lacphiolus, or jaundice. Not so long ago, this plant was very popular among gardeners. But today it is not so widespread anymore.

Jaundice is able to decorate any flowerbed.

Its flowers, as a rule, are colored in warm yellow shades. That is why this flower is also commonly called "yellow periwinkle". This plant is native to the Mediterranean. However, it can also be found on the Crimean peninsula and in the Caucasus.

Peculiarities of cheiranthus

There is slight pubescence on the surface of the thin, weakly branched upright shoots.

The bush can reach a height of 0.4-1 meters. The entire surface of the stems is covered with dense, oblong foliage, arranged in a suprostrate pattern. The entire surface of the stems is covered with dense, oblong, supratrophied foliage which is oblong in shape and blue-green in color.

Bigger brushes are composed of flowers with four-petaled corollas varying from 20 to 25 mm in cross-section.

They may be colored in a variety of shades of yellow. In addition, there are cheiranthus with crimson, orange and dark red flowers. These flowers have a very pleasant fragrance.

When the bushes are finished blooming, the pods form instead of flowers. Inside the pods are brownish, small seeds (one gram has about 500 seeds).

Most Jaundice varieties bloom during the last summer weeks. However, there are also varieties that bloom from April to May.

Growing cheiranthus in your garden is quite easy. It will suffice to follow simple agronomic rules and to provide the flower with a minimum of care in a timely manner.

Sowing seedlings

Sowing Heiranthus seedlings is done in very early spring.

But it takes about 2 months to plant the seedlings permanently in the garden.

You need a special seedling box or a wide container. Use a light soil mixture rich in nutrients to fill it. Since the seeds are very small, it is advisable to mix them with sand before sowing. This way you will be able to sow them more evenly.

Water the seeds with a sprayer and cover them with clear film or glass. Put them in a cool (16 to 18 degrees) place with diffused light. Do not forget to air the seeds every day and also water them if necessary using a sprinkler. After the first seedlings appear, remove the foil.

Sprouting seedlings into individual small pots is carried out after they have formed two true leaf plates.

Transplant the seedlings into the garden only after the soil and air have warmed up well (approximately from the middle of May).

With seedlings, only annual varieties and species are recommended to be sown immediately into the garden.

Sowing into the open ground

Sow seeds of biennials into the open ground in May. Level the surface of the pre-cultivated area and distribute the seed evenly over it. It should be incorporated into the soil with a rake and then the seeds are moistened with a watering can.

The seedlings that emerge need to be thinned, and excess bushes can be transplanted elsewhere.

In regions with frosty winters in August, it is recommended to dig out and plant in a pot that is moved indoors. This flower is able to withstand frosts up to minus 18 degrees, and the adult bushes are more cold-resistant.

In regions with warm and mild climates, the jaundice is often sown under the winter. And it also propagates very well in such regions by self-sowing.

Selecting a suitable site

Picking a well-lit site that is well protected from strong winds and draughts is recommended for growing cheiranthus. Waterlogged and low-lying areas are not suitable for planting. If the groundwater is very close to the soil surface, a high bed should be constructed for planting yolkweed. It is also highly undesirable for planting such a plant in areas where crops belonging to the Cruciferous family have been grown before.

The soil on the site should be fertile, well permeable to water and air, and have an alkaline or neutral reaction.

When there are approximately 15 days remaining prior to sowing or planting cheiranthus sprouts, the soil should be turned over to the depth of the spade-hoe and organic matter (humus or compost) should be added.

Planting rules

Seedlings are planted in previously prepared planting holes. In doing so, they should be sized according to the size of the root system. Plant the seedling in the hole and cover it with earth. At the same time, make sure that the root neck is at the same level with the surface of the soil.

The distance between adjacent bushes can vary from 20 to 30 centimeters. Make sure to water the planted plants.

Care for cheiranthus

Pouring

Pouring cheiranthus should be systematic and moderate. Keep in mind, however, that this crop is much easier to tolerate a brief drought than a stagnant liquid in the roots. Moisten the soil only when its top layer is completely dry.

Do not forget to systematically loosen the surface of the plot and remove weeds.

Fertilizers

Fertilize the bushes in good time for more lush flowering. First of all, fertilizer is applied directly into the soil while preparing the site for planting the jaundice. After about half a month after planting seedlings in the open ground, conduct their first feeding. Perennial species and varieties are fed at the very beginning of the spring period.

Also bushes need additional nutrition and during the formation of buds. Organic fertilizers and mineral complexes are suitable for fertilizing.

Trimming and pruning

To make the bush more lush and branch well, the upper parts of the shoots should be pruned regularly. So that new buds form as quickly as possible, don't forget to remove any buds that have started to fade. If you are growing cheiranthus as a perennial then make sure to cut off all the dead stems in the spring.

Hibernation

In medium latitudes it is recommended to cover the plant over the winter with a thick layer of mulch (fallen leaves). Remember that the bush can withstand a short-term drop in air temperature to minus 18 degrees. If the frost is more severe, however, it will kill the flower.

Diseases and pests

Diseases

Most dangerous to cheiranthus are diseases such as:

  1. White rust, or white rot. The affected shrub has damaged foliage and shoots and loses its ornamental quality.

    Cut out all affected parts of the plant and spray the bush with a fungicide solution.

  2. Kila. It damages the underground part of the bush, more specifically its roots. In order to prevent this, during the preparation of the site for planting, the soil must be limeed. Also avoid stagnant liquid in the soil and do not put too much nitrogen into it.

Pests

Earth flea, also called cruciferous flea, may settle on the yellowberry. You can get rid of the pests with insecticides.

Most commonly used for group planting in a flowerbed. Beautiful inflorescences of warm tones look very spectacular, while being uplifting.

Such flowers also look great in mixborders, stony gardens, squares and alpinaries.

For planting low-growing varieties of cheiranthus often choose baskets, containers or pots for flowers. You can use them to decorate a balcony, porch or pergola.

When growing chelostrum in a bed next to it it is recommended to plant heliopsis, tulips, linarias, violets Wittrock, poppies, alliums, narcissus, soapberry, forget-me-not or Iberis. Their scent is very similar to that of lilacs or matiola night violets. The plant is often used in the formation of floral compositions.

It is even grown on an industrial scale for cuttings.
