Dill (gone to seed)

"Cultivation

Successful cultivation requires warm to hot summers with high sunshine levels; even partial shade will reduce the yield substantially. It also prefers rich, well drained soil. The seeds are viable for 3–10 years.[citation needed].
The seed is harvested by cutting the flower heads off the stalks when the seed is beginning to ripen. The seed heads are placed upside down in a paper bag and left in a warm dry place for a week. The seeds then separate from the stems easily for storage in an airtight container.
[edit]Companion Planting

When used as a companion planting, dill draws in many beneficial insects as the umbrella flower heads go to seed. Fittingly, it makes a good companion plant for cucumbers. It is a poor companion for carrots and tomatoes.[6]"-Wikipedia
