Jewelweed

Jewelweed (Impatiens capensis)

Jewelweed is a moisture-loving annual native wildflower of eastern and central North America, recognizable by its translucent succulent stems, dangling orange flowers, and seed capsules that explosively spring open when touched. It is especially valuable in wet woodland edges, floodplains, streambanks, rain gardens, and other places where many conventional garden flowers struggle. Its nectar-rich flowers have an important relationship with Ruby-throated Hummingbirds and bumble bees, while the succulent stems and leaves have a long history of topical use in North American folk herbalism.

Key Characteristics

A hummingbird flower built around a nectar spur
Each orange flower hangs like a tiny pendant and ends in a curved nectar-bearing spur. Ruby-throated Hummingbirds (Archilochus colubris) are important visitors, pushing into the flower for nectar and transferring pollen as they move between plants. Bumble bees also visit the flowers, making a large stand remarkably active during its long summer bloom.

Traditional topical use of the succulent plant
Fresh Jewelweed stems and leaves have traditionally been crushed and applied externally to irritated skin, including after encounters with poison ivy and stinging nettle. The juicy aerial parts have also been incorporated into washes, poultices, and soaps. Although Jewelweed is famous as a folk remedy for poison ivy, evidence for treating an established poison-ivy rash is limited, so its traditional reputation should not be presented as a guaranteed treatment.

An annual that moves through wet landscapes
Individual plants live for only one growing season, but Jewelweed is an enthusiastic self-sower. Mature capsules build internal tension and burst when disturbed, throwing seeds away from the parent plant—a mechanism called explosive dehiscence. This allows colonies to shift naturally through moist openings, particularly where periodic disturbance creates exposed soil for germination.

Excellent for streambanks and wet woodland transitions
Jewelweed thrives in the medium-wet to wet conditions found along streams, drainage corridors, pond margins, floodplains, rain gardens, and moist woodland edges. Its succulent growth can rapidly occupy seasonal openings among taller perennials, shrubs, sedges, and ferns. Because it can reseed heavily in favorable conditions, use it where a dynamic, naturalizing colony is desirable rather than where plants must remain in precise positions.

Late-season height from a single year's growth
Despite being an annual, Jewelweed can grow several feet tall in rich, moist soil. It develops quickly enough to create a substantial summer herbaceous layer, then disappears after frost, leaving seed to regenerate the population the following spring. This annual cycle makes it useful for adding temporary height and flowering structure between longer-lived wetland and woodland plants.

Product Details

• Native range: Eastern and central North America
• Plant life cycle: Annual; readily self-sows
• Sun requirements: Partial shade to full shade; tolerates more sun where soil remains consistently moist
• Soil requirements: Medium-wet to wet, rich, consistently moist
• Mature height: Approximately 2–5 feet
• Bloom time: June–October
• Bloom color: Orange to orange-red with darker spotting
• USDA Hardiness zones: 2–11 as a self-seeding annual

Give Jewelweed consistently moist soil and enough room to reseed naturally. It is particularly well suited to informal streambanks, rain gardens, wet woodland margins, and other areas where its shifting colonies become part of the design. Leave some seed-bearing plants standing through late season if maintaining the population is important—the exploding capsules will handle much of next year's planting themselves.
