primula

Primroses have been a vibrant addition to the spring, woodland garden and containers for over a century. The name Primula is derived from the Italian word for spring primavera. An explosion of color in every shade of the rainbow, primroses primarily prefer cooler temperatures and therefore bloom early spring through May.

Primroses combine fabulously with spring bulbs, evergreen grasses and dusty miller. Some species such as Primula marginata are more diminutive and perfect for rock gardens or trough containers. Other species such as Primula japonica and Primula veris reseed and create naturalized drifts in the shade garden.

Primula auricula
Primula capita: Candelabra

The many types of primroses are divided into three basic categories. Candelabra types (i.e. Primula capita and Primula japonica) show off their flowers in tiered clusters of 6-8 blooms on 1-2 ½ ‘ stems. They are often short lived, prefer damp soil and reseed.

Polyanthus types (i.e. Primula vulgaris and Primula veris) bear bunches of flowers on 6-8” stems and bloom winter and/or early spring. This group includes the common primroses sold as color spots.

The third group is evergreen and heralds from mountainous areas. This includes Primula auricula which has small clusters of flat topped flowers in a unique range of color. They also have distinctive thick leaves with a powdery coating on the underside. These types are often grown in pots since they need sharp drainage and lime.

Here at Portland Nursery we will be carrying a wide range of Primroses this spring. We will have a rainbow of colors and types. Drop in to see what is new and blooming!
