Marbleseed Seeds

Onosmodium molle

  • FAST FACTS

HOW TO GROW

Sowing: To soften the hard coating on these Onosmodium Molle seeds and speed germination, pour hot water over the seeds and allow them to soak for 24 hours before planting. Direct sow in early spring, planting the marbleseed seed just below the surface of the soil. Keep the soil lightly moist until germination. This seed can also be started indoors 6-8 weeks before planting in the spring.

Growing: Water the seedlings until they become established; mature plants are extremely drought tolerant and rarely need watering. The marbleseed plant needs little care, though it does not appreciate competition and will grow best if the surrounding area is kept free of weeds.

Harvesting: These blossoms do not perform well as cut flowers, and are best enjoyed outdoors.

Seed Saving: After the flowers fade, the smooth seeds will begin to ripen from brown to white. The seeds easily fall to the ground, and should be collected as soon as they have ripened to their mature white color. Store the Onosmodium Molle seeds in a cool, dry place.

DESCRIPTION

IN-STOCK ORDERS SHIP WITHIN THE NEXT BUSINESS DAY. Named for its round white seeds, this native wildflower is becoming rare in some states. The white perennial flowers droop downward from soft, hairy stems, and prefers to grow in dry soils.
Its white, nearly round seeds earned this wildflower its common name. The marbleseed plant usually establishes itself in heavily grazed pastures or along dry roadsides where the lack of competition allows it to thrive. Noted French botanist Andre Michaux first included this genus in his 1803 publication of Flora Boreali-Americana, an authoritative work on the plant life of North America. The genus name "Onosmodium" comes from the name of a closely related herb, while the species name "molle" comes from a word meaning "soft."
