One of the easiest primula to grow! Primula vulgaris is a hardy perennial plant and it has gained the Royal Horticultural Society's Award of Garden Merit! Plants will gently form colonies if they are allowed to self seed. An excellent plant for difficult shady areas.

Type: Hardy perennial

Height: 15cm, 6"

Location: Shade or part shade

Hardiness zones: 3-8

Note: This plant species is known to cause dermatitis in some individuals.

Seeds per pack: 10

Germination: As with many perennials, these seeds can benefit from a period of moist cold to help them break dormancy. This is done by giving them a cold 'winter' period (artificial or natural), and then a warming to simulate 'spring', and time to grow! Here's how this can be done:

Obtain a planting container that has holes in the bottom for excess water to drain. Place the seeds on the surface of your growing medium, and water. Place your container in a cold area (but not freezing, perhaps a refrigerator) for 4-6 weeks. Once the cold period is completed, place the container at room temperature for them to germinate. Be sure to keep the soil moist during this entire germination period. Seedlings will sprout a few weeks, or occasionally several months, after the warming period.
