GERANIUM Perennial Geranium pratense
This popular geranium has magnificent sky-blue flowers on hardy perennial plants that will bloom prolifically all season, and are also hardy enough to naturalize! Plants form large dense clumps, and are remarkably resistant to drought.
Height: 12-18" leaves, 24" flowers.
Hardiness zones: 4-9
Safe: Considered safe, non-toxic to children and people! This is our research, though we still suggest you confirm this yourself.
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 the seeds in. 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, and in a bright area (they require light), 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.
If you are planting your seeds in late winter or spring, these seeds can be planted outdoors while it is still cool out (once the ground is workable and unfrozen), to receive the cold period naturally in the garden. It is best to use this method only if you are able to keep the soil moist for the entire germination period. Be sure to label the planting area.
