PINK EVENING PRIMROSE Oenothera speciosa
Large pink flowers bloom in mass, on medium sizes plants. Spent flowers close, and turn red, providing a nice contrast!
Hardiness zones: 5-9
Location: Sun or part shade
Seeds per pack: 20
Note: Ornamental use only. This plant and/or seeds may be poisonous.
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 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 few weeks, or occasionally several months, after the warming period.
