DRUMSTICK PRIMROSE MIX Primula denticulata
Drumstick Primula flowers are unique, in that they form balls of flowers on tall stems! Primulas are one of the first perennial to bloom in the spring, and blooms are tolerant of the cold frosts. Grow plants in part . They are ideal for planting under deciduous trees that allow sun to pass through in the spring before the leaves emerge, and later provide during the hot summer. Colors include red, pink, blue, purple, yellow and white.
Location: or part .
Hardiness zones: 4-8
Bloom time: Spring
Seed size: Small
Note: This plant species is known to cause dermatitis in some individuals.
Seeds per pack: 20
Germination: As with many perennials, these seeds require 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 just under the surface of your growing medium, and water. Place your container in a cold area (but not freezing, perhaps a refrigerator) for 5-6 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 couple of 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.
