Packet Size:10mg
Average Seed Count:250 Seeds


‘Noverna Deep Blue’ is a fascinating primula with the most intense, deep blue-violet flowers. The beautiful flared bell-shaped blooms emerge in summer in tight clusters at the top of an 8 to 10 inch stems.
This large alpine primula is native to Nepal and Tibet and is the last in the primula family to flower, throughout summer and into autumn.
The leaves are serrated and form a basal rosette with the blooms being held aloft on powdery silver-white stems. The buds and stems are covered in whitish powder called ‘farina’.

This outstanding primula needs no pre-chilling and if sown early, will flower in its first year. It is tolerant of poor weather and thrives in a humus-rich, well-drained soil in part shade. It will tolerate full sun if kept moist at all times.
Perfect for woodland gardens and partially shaded borders, the brightly coloured flowers will also add an eye-catching display to containers from summer into autumn.

Sowing: December to February or May to June
With no requirement for vernalisation, Noverna will flower from June onwards from a spring sowing. Overwinter later sowings for blooms the following year.
Sow December to February for flowering in the summer of the same year, or May to September for flowering early the following summer.

Sow seed 2.5cm (1in) apart in pots, trays or cells containing lightly firmed, moist seed compost. Sow on the surface of the compost. The seeds need light to germinate, so cover only with the lightest sprinkling of compost of vermiculite
Seal the container inside a polythene bag and place in a light position at a regular temperature of around 16 to 20°C (60 to 68°F). Germination should take place between 21 and 40 days.
Keep the surface of the compost moist but not waterlogged; germination can take 21 to 30 days and may be erratic.
Although most primula seed should germinate in 4 to 5 weeks, it is not unknown for seeds still to be germinating up a year after sowing. If any seeds have not germinated, remove the seedlings and place the pot in a shaded corner of the garden….just in case!
When seedlings have their first pair of true leaves and are large enough to handle, transplant into 7.5cm (3in) pots containing peaty compost. Hold the seedlings by their leaves, not stems and support their weight to ready prepared pots. Grow on, then gradually acclimatise to outdoor conditions for 10 to 15 days before planting out.

To get the best out of primulas plant them in humus-rich, moisture retentive soil and in partial shade. The roots should not be allowed to dry out, so incorporate plenty of organic matter when you plant and water regularly if they are in the open.Primulas can be used in most positions in a garden from bed or border to around ponds and alongside streams and even in bog and rock gardens.
Cut back after flowering. Mulch well in autumn and spring. Once established, they benefit from being lifted and divided every two years in early spring.

Plant Uses:
Shade and Woodland Gardens. Underplanting of trees. Beds and Borders. Ponds and Streams. Bog Gardens. Native and Natural planting schemes.

Many Primula species have what is known as farina; the flowers are covered with a white powdery-dusting, like flour. It is produced by many Primulas to protect them against moisture loss.

Primroses and Polyanthus.
What's the difference? Primroses have one flower per stalk, polyanthus many.
