WHITE QUEEN Of THE PRAIRIE Filipendula ulmaria
An elegant perennial with large sprays of white flowers, held high above deeply serrated and lobed foliage. It is beautiful statement plant that can be grown in sun or shade. Plants can be used in a garden setting, or used to naturalize. Plants like regular soil, or slightly moist soil.
Type: Hardy perennial
Hardiness zones: 3-9, and some sources suggesting as cold as zone 1!
Height: Up to 5', 150 cm
Location: Sun or shade
Seeds per pack: 5
Germination: As with many perennial seeds, these seeds benefit from a period of moist cold to help them grow. 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 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.
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.
