Description

The Polyanthus primroses in this mix, also called Primula polyanthus Large Flowered Mixed, are among the prettiest spring flowering plants. They are robust perennials, often grown as bi-annuals, that produce onwards from the end of winter, a profusion of large flowers in a very wide range of colours from white to cream and yellow to orange and purple, on top of semi-evergreen foliage arranged in rosettes.

Primula of the Polyanthus group or Primula x polyantha are hybrids derived from different species (P. eliator, juliae, veris and vulgaris), native from many temperate regions of the Northern Hemisphere. These perennials belong to the large family of Primulaceae which consists of about 400 species. The Large Flowered Mixed selection is made up of plants measuring 25 cm tall and wide that form 10 to 20 cm rosettes with veined, slightly wrinkled, dark green, evergreen or semi evergreen leaves. They flower in March-April. The flowers are grouped in umbels of 3 to 15 flowers with yellow or contrasting centres, carried by thick stems, and display a wide variety of colours. 

Primrose is versatile and really easy to grow, even if it sometimes disappears because of dry summers or severe frosts. It deserves to be in every garden. Colourful, abundantly flowering and very cheerful, it marks the return of spring. Planted in flowerbed borders or window boxes on a balcony, these small plants are ideal companions for tulips and forget-me-nots. They are ideal in borders, low-lying beds under the cover of broad-leaved trees, in rock gardens and lawns, planted among snowdrops and violets. The leaves and flowers are edible and can be eaten raw or cooked.

Planting and care

Sow at the end of winter in a special seed starting mix. Place the seeds on the surface of the soil. Seal within a transparent plastic bag and cover with a plate of glass. Place in a partially shaded but bright spot, as light promotes germination. Keep the soil moist but not wet. Germination usually takes 10-15 days at 15-18 °C. Higher temperatures can inhibit germination.
 
Transplant the seedlings into 7.5 cm diameter pots. Grow them in a cool, moist environment and then transplant them into the ground outside, taking care to leave 23 cm between each plant.

Plant primroses in the morning sun or in partial shade, in well-drained but fertile, humus-rich soil. These plants do not fare well in soil that dries in summer or soil that is waterlogged in winter. Water well in the weeks following transplanting, especially in dry weather, to ensure their recovery. Regular watering in the summer will also be necessary in case of extreme heat and drought. These easy-to-grow plants will not need any special care apart from the removal of wilted flowers and leaves.

Growing in a pot:

Remember to improve drainage at the bottom of the container by putting a layer of gravel, shards of earthen pots, or clay pebbles to facilitate the evacuation of water and avoid asphyxiation of the roots. A mixture of leaf compost and garden soil will do the job just fine.

Place the pot in partial shade or in the sun and water regularly to keep the soil always slightly moist to sustain flowering. Every two week, add a little fertilizer for flowering plants to the irrigation water and remove faded flowers to extend the flowering period.
