Self-Seeded

A plant's habit of shedding seeds in the immediate area. They then germinate without outside help. Both annuals (i.e. cleome and marigolds) and perennials (i.e. purple cone flower, rose campion and columbine) self sow. To eliminate or cut down on this (as some perennials can really become weeds if left to continually self sow), dead head spent blooms. This will not only keep the garden more tidy, but will also reap more blooms.
