Soil & Growing Conditions

Water: consistent moisture, dislikes waterlogging; performs best in woodland or streamside settings (RHS)

Soil pH range

6 7.5

Span reflects genuine variation between the cited authorities, not a single agreed figure.

Growth Stages

Stage	BBCH	Notes
Sowing	0	Sow fresh seed directly where plants are to grow, on the compost surface under light (seeds need light to germinate, do not cover), at 10-13C; germinates in 1-3 months. Dried seed needs 4 weeks cold stratification (RHS, NC State Extension).
Establishment	1	Dislikes root disturbance -- avoid transplanting once established; space plants 60-90cm apart (NC State Extension, RHS).
Stem and leaf growth	3	Grows to 2-3m tall with robust upright stems; performs best with consistent moisture (RHS).
Flowering and stem harvest	6	Flowers within 2-3 years; harvest young tender stems in late spring before flower stalks form (RHS).

Harvest & Storage

When to pick: Harvest stems young and tender in late spring before flower stalks form; young shoots, roots and leaves are also edible, and seeds can stand in for fennel (RHS, NC State Extension).

Angelica, an Architectural Edible Herb

Dome-shaped flower umbels

RHS: dome-shaped flower umbels in white, yellow-green, pink or purple-red, appearing summer through early autumn.

The main culinary product

The tender young stem is the main culinary product, harvested in late spring before flower stalks form.

Up to 3m tall

RHS: robust upright stems reaching up to 3m high, among the tallest plants on this site.

Sow where it's to grow

Angelica dislikes root disturbance -- seed is best sown directly where plants are to grow rather than transplanted.

Thrives near water

Performs best in woodland or streamside settings with consistent moisture -- its deep tap root dislikes waterlogging but also dislikes drying out.

   Tall, aromatic, architectural plants producing robust upright stems up to 3m high, with dome-shaped flower umbels in white, yellow-green, pink or purple-red, summer through early autumn. Native to Europe and central Asia (about 100 species worldwide). Sun or partial shade, performing best in woodland or streamside settings with consistent moisture. Well-drained, moist soil; deep tap roots dislike waterlogging. Height 2-3m typically (some varieties like 'Ebony' only 75cm), plants spaced 60-90cm apart. Flowers within 2-3 years. Sow fresh seed on the compost surface under light at 10-13C, germinating in 1-3 months; dried seed needs cold stratification (4 weeks refrigeration); self-seeds readily. Pests: aphids, slugs and snails, celery leaf mining fly. Diseases: powdery mildew during dry summers. Stems of A. archangelica and A. edulis are the culinary parts, harvested young and tender in late spring before flower stalks form.
