The Story
Plant Bio
Anethum graveolens, dill, is an erect branching annual herb from the Mediterranean and western Asia, reaching two and a half to five feet in flower. Hollow ridged stems carry very finely divided blue-green feathery leaves, and broad flat umbels of tiny yellow flowers open in summer, followed by the flat ribbed seeds.
It is the larval host of the black swallowtail butterfly, so caterpillars stripping the foliage are worth planting extra for rather than removing. Dill bolts to flower quickly in heat and once it does the leaf crop is over, so sow a short row every three weeks through the season rather than one large sowing.

Common Questions
Dill questions
What zones can Dill grow in?
Dill is hardy in USDA Zones 5–8. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.
Is Dill deer resistant?
Yes — Dill is rated deer-resistant. Deer typically pass it over, though extreme hunger can override any plant's defenses.
When does Dill bloom?
Dill typically blooms in summer through late summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Dill need full sun?
Dill does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
Is Dill drought tolerant?
Yes — once established (usually after the first full season), Dill handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
