Caltha palustris alba
MARSH MARIGOLD WHITE
Marsh Marigold is a water-loving plant, growing readily in wet or boggy soils. Plants appear early in the spring. White flowers, with bright yellow centers, appear on top of large shiny leaves! Plants look lush, and are a welcomed sign in spring. These plants are often used in water-gardens and ponds, and are found naturalized in boggy areas. They are extremely cold resistant, too! Plants behave, and do not become invasive.
Type: Bog plant, water plant, moist soil area
Height: 60cm, 24"
Hardiness zones: 5-8
Note: These seeds and plants can be harmful if eaten. Ingestion can cause illness such as vomiting or diarrhea.
Seeds per pack: 10
Germination: As with many hardy perennials, 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:
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 very wet 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 wet.
