Dill

Dill (Anethum graveolens) is a fast-growing, aromatic annual herb in the celery family, featuring 3–5 foot, hollow, erect stems and feathery, blue-green, dill weed foliage. Known for its delicate texture, it produces flat, yellow, umbrella-shaped flower clusters (umbels) in summer, which turn into flavorful, pungent seeds. 
Key Characteristics:
Appearance: Fine, plume-like, fern-like leaves that are soft to the touch.
Structure: Single, main, slender, hollow stem, similar to fennel.
Flowers/Seeds: Small, bright yellow flowers arranged in large, flat-topped, 10-inch diameter umbels.
Aroma/Flavor: Strongly scented and tangy, with a pungent, grassy flavor.
Size: Typically grows to a height of 2 to 5 feet, with a spread of about 1 to 2 feet.
Lifecycle: An annual, often self-seeding for a return in subsequent years. 
Growing Conditions:
Light: Full sun (6+ hours per day) is essential.
Soil: Thrives in well-drained, moderately rich soil, but is adaptable.
Water: Needs regular, moderate moisture to avoid premature bolting.
Uses: Used as a culinary herb (fresh or dried) for leaves and seeds, in pickling, and as a beneficial insect attractor (e.g., caterpillars, bees, wasps).
