Expect to find these delightful volunteers in pathways, containers, and tucked between larger plants throughout your garden.
8. Larkspur (Delphinium elatum)
Spikes of intense blue flowers reach toward the sky, then generously scatter their future generations below. Seed pods develop along the tall stems, releasing seeds when mature.
These plants prefer cool, moist conditions and will establish colonies in suitable microclimates. Young seedlings often appear in fall and overwinter as small rosettes.
Annual larkspur varieties are particularly good self-seeders, creating stunning displays that improve with each passing year.
9. Love-in-a-Mist (Nigella damascena)
Feathery foliage surrounds delicate flowers that transform into inflated, striped seed pods resembling tiny hot air balloons. These ornamental pods are as beautiful as the flowers themselves.
Seeds rattle inside the papery pods until they split open, releasing numerous black seeds. Plants readily self-seed in loose, well-draining soil and full sun.
Both flowers and seed pods make excellent additions to fresh and dried flower arrangements.
10. Lunaria (Honesty Plant)
Heart-shaped leaves give way to clusters of purple flowers, but the real magic happens afterward. Flat, round seed pods develop that look like silver coins when dried.
These translucent pods eventually split to reveal dark seeds that scatter naturally. Plants often skip a year between major flowering, but scattered seedlings ensure continuous presence.
Dried seed pods are treasured for winter arrangements, earning this plant the nickname “money plant” or “silver dollars.”

White varieties are especially fragrant and tend to be the most reliable self-seeders in the garden.
12. Poppies (Papaver)
Papery petals unfurl to reveal silky flowers that seem too delicate to be such determined spreaders. Distinctive pepper-shaker seed pods develop after blooms fade.
Wind shakes seeds through tiny holes in the pod tops, dispersing them naturally. Iceland poppies and Oriental poppies are particularly good at establishing new colonies.
Seeds often remain dormant until soil conditions are perfect, sometimes surprising gardeners years later with unexpected blooms.

Native plant enthusiasts love this species for its wildlife value and low-maintenance spreading habit in naturalized areas.
17. Yarrow (Achillea millefolium)
Feathery foliage and flat-topped flower clusters make this drought-tolerant perennial both beautiful and practical. Flowers dry naturally on the plant, releasing seeds gradually.
Seeds germinate easily in disturbed soil and quickly establish new plants. Yarrow spreads by underground rhizomes as well, creating dense colonies over time.
This tough plant thrives in poor soil and full sun, making it perfect for low-maintenance areas that need reliable color.
18. Catmint (Nepeta)
Fuzzy gray-green leaves and spikes of lavender-blue flowers create a soft, romantic garden presence that cats absolutely adore. Spent flower spikes produce small nutlets containing seeds.
Seeds scatter naturally when dried flower heads are disturbed by wind or animals. Plants also spread by underground stems, forming attractive clumps.
Regular shearing after flowering encourages fresh growth and prevents excessive self-seeding while maintaining the plant’s neat appearance.
19. Shasta Daisy (Leucanthemum x superbum)
Classic white petals radiating from golden centers embody the essence of traditional garden daisies. After blooming, seed heads develop that eventually release numerous seeds.
These cheerful flowers readily self-seed in sunny locations with well-draining soil. New plants often appear around the parent clumps, gradually expanding the colony.
