Main species
The genus Primula includes about 500 species native to the temperate and cold zones of the Northern Hemisphere, South America, Java, South Asia, China and Japan. The species of the genus can be divided into late-winter and spring-flowering primroses and summer-autumn flowering Primroses.

The species of the genus include annual and perennial herbaceous plants, from a few centimetres to several decimetres tall, which can have basal rosette leaves that are sessile or petiolate, and which can produce very colourful flowers gathered in umbels, flower heads, clusters or overlapping whorls, surrounded by bracts or supported by long stems.

Primrose
Primroses are rustic and resistant plants, able to overcome the winter in different ways, therefore the temperature is not a limiting factor in cultivation. They love bright exposures, but not direct sunlight, especially in midsummer.

When grown in pots, the plant can be easily moved. When grown in the open ground, it should be placed in a more sheltered position from the sun, for example at the foot of trees and shrubs that provide shade, avoiding southern exposure.

Primroses do not require any special care or attention, so growing them is quite simple.

How long do Primroses last?

Most species of primrose have a fairly long lifespan, over 2-3 years of life. The lifespan of primroses is also determined by the quality and nutrient richness of the growing soil, within certain limits therefore the maximum aesthetic yield can be ensured to the plant with adequate and continuous cultivation practices.

Where to keep primroses? Primroses like to be placed in a very bright place, but never exposed to direct sunlight.
It prefers cool environments. The ideal temperature is around 10-15 °C, but it is advisable that it does not exceed 16 °C especially during the flowering period as higher temperatures can significantly reduce it.

It is important to remember that Primroses love cool temperatures and are allergic to heat: if you want to keep them beautiful for as long as possible, you should choose a fairly cool area of ​​the house.

Temperature
It prefers cool environments. The ideal temperature is around 10-15 °C.

Light
Primula requires exposure to a very bright place, but must never be exposed to direct sunlight. When grown in the open ground it is necessary to find a position more sheltered from the sun, such as at the foot of trees and shrubs that provide shade, avoiding southern exposures.

Soil
The ideal soil for Primula is medium textured, fresh, with a good supply of organic matter. Poorly draining soils should be avoided, with the exception of Primula japonica.
When preparing the soil, it is advisable to amend the soil with mature organic matter, such as manure, pelleted manure, worm castings or compost.

Watering
Watering should be regular, not excessively abundant, but such that the soil remains moist but not soaked; it is a mistake to let excess water stagnate in the saucer. Spraying the foliage is excellent, but be careful not to wet the flowers, which could be ruined.
During the summer it should be watered regularly to keep the soil always moist. When the plant is in bloom, constant watering is very important.
Be careful of water stagnation which the primrose does not tolerate.

Primula seed propagation

The seeds should be arranged in parallel rows using a seed compost. Given their small size, they should be pushed under the soil using a flat piece of wood.

It is then necessary to cover the tray with a sheet of transparent plastic to obtain the ideal temperature and it should be placed in a place with a temperature of 12-15°C and in the shade. The plastic should be removed daily to eliminate condensation and to check the humidity of the soil.

The seeds germinate after about fifteen days. Then remove the cover and place the tray in a bright position with good ventilation.
