PRIMROSE BLUE CRESCENDO Primula eliator
One of the first flowers to bloom in spring! These plants produce stunning deep-blue flowers that hold their colour throughout spring. The plants will form a large clump over time. Plant under or near deciduous where they will receive sun in early spring, and shade in summer once they leaves fill out. This plant has been awarded the Award of Garden Merit (A.G.M.) from the Royal Horticultural Society.
Type: Hardy perennial
Height: 30cm, 12"
Location: Shade or part shade
Hardiness zones: 5-8
Note: This plant species is known to cause dermatitis in some individuals.
Seeds per pack: 5
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.
Alternatively, these seeds can also be planted outdoors in fall, winter, or early spring, while temperatures are still cold (but ground is workable) to germinate naturally in spring. Be sure to mark the area where you planted them, and that the soil is consistently moist.
