Опис
Scatter seed on the surface of moist, humus-rich, slightly acidic soil in partial to full shade in early spring; jewelweed is a tall native annual of moist woodlands, stream banks, and swampy areas throughout most of North America — one of the few native annuals that thrives in deep shade and moist conditions. The orange, trumpet-shaped flowers are uniquely constructed with a curved spur and are the primary nectar source for ruby-throated hummingbirds in eastern North America during their southward fall migration. The ripe seed pods burst explosively when touched (hence 'touch-me-not'), flinging seeds up to 3–4 feet. Fresh crushed stems and leaves are widely used as a folk remedy to relieve the itch of poison ivy contact, with some evidence supporting anti-inflammatory compounds in the juice. Jewelweed is a powerful self-sower that naturalizes in moist, shaded areas and requires no care once established.

Direct sow seed on the soil surface (seeds need light to germinate) in moist, slightly acidic soil in partial to full shade just before last frost; jewelweed self-sows prolifically and typically establishes as a self-sustaining colony once introduced — no further planting is needed after the first year.
