Angelica, an Architectural Edible Herb
References
-
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.
