selfseeds

Selfseeds refers to the phenomenon of plants producing viable seeds that disperse, germinate, and grow into new plants with little or no human intervention. In gardening and horticulture, self-seeding plants are often valued for their ability to renew themselves from year to year, providing ongoing color and continuity in borders, meadows, or wildflower plots. They can also produce volunteers in nearby beds or containers.

Seeds reach new locations through various dispersal mechanisms, including gravity, wind, water, and animals. Some plants shed dry seed heads that persist into autumn, while others rely on fruit capsules that split open. Seed dormancy and environmental cues such as temperature and moisture influence when and where germination occurs. In managed settings, gardeners may encourage self-seeding by leaving seed heads intact, or intentionally collect seeds for future sowing.

Ecologically, self-seeding contributes to plant community resilience by supporting genetic diversity and enabling rapid recolonization after disturbance. It can provide habitat and food for wildlife, but it may also lead to volunteer growth that competes with desired plants or spreads beyond intended areas.

Common examples of self-seeding garden plants include cosmos, calendula, nigella (love-in-a-mist), poppies, lupines, zinnias, and bachelor’s button. Some species, like dandelions, readily self-seed in lawns and wild spaces. In ornamental mixes, a high self-seeding rate can create a naturalistic look, though it may require management to prevent unwanted spread.

Management tips include leaving selected seed heads to mature, harvesting seeds for future plantings, or removing spent plants before seed set if self-seeding is not desired.
