How to observe cowslips

How to recognise the cowslip?

The cowslip (Primula veris) is a spring flower. It is a perennial plant, which means that the same plant grows and blossoms in the same place for many years. Its closest relatives in the Estonian nature are the bird's-eye primrose, the oxlip, and the common primrose. 

You can read more about the genus Primula here: 

The cowslip is a herbaceous plant up to 10 to 30 cm tall on average. It has green elongated leaves up to 20 cm long, and one plant can have multiple stems. At the end of the stems, there are deep yellow bell-shaped nodding flowers with orange dots in clusters of 5 to 16 blooms together keeping to one side.

The cowslip is one of the first harbingers of spring. It usually begins to blossom at the beginning of May and flowers usually for a couple of weeks. In a cooler weather, the blossoming can also begin later and last until mid-June.

The cowslip is quite common in Europe- It prefers dry or moderately moist limy soils, which are more common in coastal areas. However, this does not mean that the cowslip does not grow in more acidic soil at all. It can mostly be found growing on grasslands, in parks, on forest edges and by the roadside. It usually prefers sunnier spots.
