Inside the seedpod are round seeds that at first are light-colored, soft and milky inside. Later they turn brown and develop a hard coat. Each plant can have several stems, each stem can have several flower stalks and each flower stalk can have ten seedpods with five seeds. It adds up to a lots of seeds. This makes me wonder why we only found one seedling this spring and last spring. Maybe I should experiment by planting a dozen seeds in small area so they are at the right depths in the soil and protected by mulch. Results next year.
