Anna is back to tell you about seed dormancy. Why don’t seeds sprout as soon as they fall from their parent plant? In many cases, it’s simply too early. In cold climates, the fragile seedlings wouldn’t have a chance of surviving the winter. Instead, they rest until certain conditions are met.

Speaking of money, Idaho Botanical Garden has a grant named after this plant – The Lunaria Grant – which helps other organizations fund their plant-themed education projects.
