Primrose

General

With varied, brightly colored flowers primroses (Primula) provide good mood in winter gray. They are among the first flowering plants in the new year and live up to their name, because "Primula" means "the first". Primroses are known especially as small potted plants from the supermarket. But actually primroses are very perennial wild and garden shrubs that are native to the entire northern hemisphere. The genus Primula comprises over 400 species and grows steadily through new crossings. Auricles (Primula aurikula) occupy a special position. In England, lovers present their treasures at Auricle shows, where the most beautiful are awarded.

The majority of the primroses are perennial, deciduous, herbaceous plants that form a subterranean network of rhizomes. Primroses are resistant and not very demanding, which makes them easy to care for garden plants. The flowers of the primrose, which appear from February to May, usually consist of closely spaced small inflorescences, which are similar depending on the type of umbels, panicles or grapes. Virtually all colors are represented, from white to yellow, pink and red to violet, with the throat almost always being richly yellow. The flowers of the primrose sit on a up to 25 centimeters high, slightly hairy stems, sometimes upright, sometimes nodding, which grows up from a leaf rosette. Some wild species resemble a bunch of keys in the arrangement of their flowers, which has given them the trivial name cowslip (Primula veris).
Well-known pot plants and garden plants are the primroses (Primula acaulis), the primula (Primula denticulata), the primula (Primula obconica), the briar or lilac primrose (Primula malacoides) and the rose primrose (Primula rosea ). Particularly beautiful are also the primrose primulas (Primula bulleyana and Primula Bullesiana hybrids), in which the flowers are arranged like a whorl along the stem. They bloom a little later than other primrose species, between June and July, sometimes even into August and grow up to 50 centimeters high.

Attention! Most primrose species contain the contact allergen primin, which can cause skin irritation and allergic reactions. It may therefore be advisable to wear gloves during planting. With ample consumption, the active ingredient causes stomach pain and nausea. The plants should therefore be placed out of the reach of children or pets.

Planting and care

Most primroses are offered in spring as Dekoblume in small plastic pots. This gives the appearance of a disposable item. In fact, the small early flowering plants are perennial and can be planted well in the garden in spring or autumn. Most primrose species prefer a nutrient rich soil in sun or part shade. For this, some compost should be incorporated into the substrate during planting. Primroses thrive both in the pot and in the bed. For the pond edge planting and for other very moist substrates, the rose primrose is particularly suitable, as it does not react as sensitive to wet feet as her sisters. If they have enough space in the discounts, the primroses spread out quite quickly due to their rhizome. The easy-care flowering plants do not require much attention, only blown and damaged plant parts should be regularly cleaned. Always keep the substrate moist but not wet. Dryness and blazing summer sun do not like primroses. For budding in spring can be given with a complete fertilizer jump start. Further fertilizer inputs over the year are no longer necessary in humus-rich soils.

use

Especially at the beginning of the year pot primers are offered everywhere. They are therefore often the star in colorful arrangements on the windowsill or on the doorstep. Both in the flower box and in the bed, primroses should be arranged in small groups. Together with tulips or daffodils, the colorful springblooms wake up spring fever. Later in the year, horned violets, ranunculus, bellis and spring marguerites follow as suitable planting partners. In a well-visible place, embedded in soft moss, surrounded by a wicker wreath or combined with green plants such as ivy and potted grasses, they become stylish eye-catchers. Stem primroses (Primula elatior) are a showy appearance because their flowers sit on about ten-centimeter-high stems. Even the primula (Primula denticulata) raises its flower balls in the air.
Some years ago the rose primroses, which were traded as treasures only a few years ago, celebrated their breakthrough with varieties in yellow, white, orange, red and blue. Their particularly densely filled flowers spread nostalgic charm. Not only in the pot, also in the garden, the primrose is a pretty spring messenger. It is suitable for planting hedges, shrubs and trees. Since the primrose retreats partially to the ground in autumn, it should be combined with ferns, grasses or late-flowering perennials in the bed. And even as a cut flower, the long-stemmed primroses are well-suited - together with other low early flowering plants, they can be combined into pretty spring bouquets.

wintering

Since many Primros originate from the alpine area, they are in the bed generally quite hardy. Especially the pillow-primrose, which is one of the best-selling potted plants, is a hardy perennial that actually likes it better in the flowerbed than in the pot. Only in severe night frosts should the primrose flowers be covered. Primroses in the pot are best kept in a bright, cold place over the winter.

proliferation

Primroses form subterranean rhizomes, so their multiplication is very simple. The small plants can be easily divided after flowering with a spade and at least 20 centimeters further used. Also on the sowing primroses can be propagated. Some species sow themselves.

Diseases and pests

The robust primrose plants are extremely resistant to diseases. If the plant is too wet, gray mold (botrytis) or root and stem rot can occur. The rot is manifested by pale green discoloration or withering of the leaves. Here only helps transplant. Dispose of moldy plants. Pest infestation is rarely observed in planted primroses. Sometimes the weeping weevil likes them. In the glasshouse, on the other hand, aphids, leafminers or spider mites are common.
