Plant characteristics and classification of cowslip

Origin and occurrence of cowslip

The cowslip is a plant native to Europe whose range extends from Western Europe to West Asia. It is a common weed, which can be found especially in dry locations such as poor meadows, slopes, regions with sandy soil and wasteland. In the mountains, cowslip is occasionally found up to 2,000 m (6,500 feet) altitude.

Not to be mistaken is the common cowslip (Primula veris) with the oxlip (Primula elatior), which in contrast can be found on damp locations such as streams, humid forest areas or at river and lake shores.

Plant order of cowslip

The common cowslip (Primula veris) belongs to the large family of primrose plants (Primulaceae). In the narrower classification, the species belongs as well as their closer relatives the oxlip or the snowbell to the genus of primroses (Primula). Altogether this kind counts more than 500 kinds.

Look and characteristics of cowslip

Plant

Cowslips are typically herbaceous and perennial plants, which usually reach stature heights between 10 and 40 cm (4 and 16 in). The plant forms strong, thick and strikingly fibrous rhizomes. These rhizomes are hibernating organs of the plant.

Leaves

The thick leaves of the cowslip are usually of light green color, lanceolate to ovate, strikingly structured and slightly sawn at the edge. From the base of the leaf to the tip of the leaf, white to slightly yellowish colored leaves pass through. The leaves are up to 20 cm (8 in) long and 5 cm (2 in) wide and arranged as a rosette. Typical leaf stems are not recognizable, but present.

Flowering

Its flowering period is from March to May. Then, on short hairy stems, tiny bright yellow tubular flowers with pale green calyx are formed, arranged in umbels. What distinguishes the common cowslip from other species are the orange spots found in the middle of each petal. In addition, the flowers exude a pleasantly sweet scent.

Ripening

After flowering, spherical capsules are formed with pale green bracts containing the seeds of the cowslip. The plant tends to self-sowing and forms at appropriate locations quickly dense populations. As a rule, the dark brown seeds are ripe from late August to mid-September.

Cowslip – cultivation and care

Overview of cultivation conditions

Location – sunny to partially shaded

Soil sandy, low in nutrients and calcareous

Sowing time September to October

Planting distance at least 25 cm (10 in)

Fertilization not necessary

Watering sparingly

Harvest spring (only self-cultivation)

Location

Ideal for cowslips are sunny locations with calcareous, barren, sandy and therefore nutrient-poor soils. But it also grows in the semi-shade, which sometimes gets better in very hot regions.

Soil

The cowslip finds optimal growth conditions in nutrient- and humus-rich soils with a high calcium content. Fresh, loamy clay soils are ideal. But, too nutrient-rich soils cause that the roots burn and the cowslip can no longer absorb nutrients.

Sowing

If you want to cultivate cowslip from seeds, some details are to be considered. Cowslip seeds need several weeks of freezing temperatures to germinate. Before this cold period, the seeds should be kept moist and warm for a short time. In the field, from mid-September to early October, the seeds can be incorporated directly into the soil (about 1.5 cm deep (0.6 in)). A planting distance of at least 25 cm (10 in) per plant should be maintained. The germination time can be up to 6 months.

Planting

Full grown plants can be transplanted outdoors from mid-May on. The cultivation with finished plants is much easier than the cultivation of seeds. A planting distance of 25 cm (10 in) should be kept, otherwise diseases may come up. Incidentally, cowslip also grows very well on balconies or terraces.

Division

Dividing is a great way to lighten up stocks, but also to rejuvenate older plants and inspect for disease. Pest infestation or, unfortunately, very common viral infections are often most noticeable on the roots. The right time for the division is after flowering.

Watering

Cowslips are adapted strategists that usually do not need special care. Only on very hot summer days or in very small planters more frequent watering is necessary. In the field, occasional watering is sufficient at longer dry periods. Shorter dry periods do not affect the cowslip in most cases.

Fertilization

Additional fertilization is not necessary in the field. For potted cultures, a standard herbal fertilizer, which should be administered twice a year is sufficient.

Diseases and pests

As a rule, cowslips are not attacked by pests. The plant contains some secondary ingredients that have a deterrent effect on many predators. Exceptions are some weevils and occasionally thrips. Most illnesses usually arise as a result of overprotective care or locational difficulties. For example, yellow leaves are often produced if the plant was watered too much. In rare cases magnesium deficiency is the cause. Very rarely, an infestation with nematodes can be observed. Holes and brown spots on the leaves may indicate this. Older cowslip species are susceptible to various viral diseases caused, for example, by mosaic virus. Often the viruses are transmitted by tools or aphids.

Wintering

Common cowslips are frost tolerant and hardy. Towards autumn, the leaves usually die off and reappear in March. In mild winters it may also be possible for the leaves to stay.

Buy cowslip – What to pay attention to?

Fresh plants can often be bought on plant markets, DIY markets and of course online. When buying, the leaf structure and the underside of the leaves should be looked at closely. If yellow margins, minor herbivore damage or small white dots are visible, you should refrain from buying. The price for a plant is about 3 to 5 EUR / $.

The botanical name can also be important. If you really want to buy the common cowslip, you should pay attention to the Latin name Primula veris. Occasionally, the oxlip (Primula elatior) and the common primrose (Primula vulgaris) are also sold as a cowslip. All three species, however, are completely different to cultivate. The common cowslip is the species that needs the least care.

Many manufacturers also offer seeds of the cowslip. It should be mentioned that planting with fresh plants is much easier. The prices for seed is about 2 to 4 EUR /$.

For healing purposes, dried flowers and roots can be purchase, with prices that are usually quite high. It must be differentiated, however, whether roots or flowers should be used. For persistent flu or for treatment of sinusitis, only the roots should be used as they contain high levels of the required Triterpensaponin.

There are also some ready-made products on the market, which contain cowslip extracts and also usually have a good effect.
