Jewelweed Identification Guide

Key Identifying Features

Jewelweed, also called Spotted Touch-me-not (Impatiens capensis), is a native North American annual famous for its exploding seed pods. Watch for:

• Pendant orange flowers with reddish-brown spots, dangling on thin stalks
• A distinctive backward-curving nectar spur behind each flower
• Succulent, translucent, watery stems that snap easily and look almost glassy
• Leaves that show a silvery shine underwater ("jewel" effect) when submerged
• Plants 2-5 feet tall, often in dense stands in wet shade

Leaves & Stems

Leaves are oval to elliptical, 1-4 inches long, with rounded or shallowly scalloped, slightly toothed margins. They are alternate, soft, and a bit blue-green, on slender stalks. The defining trait is the stem: smooth, hollow, juicy, and semi-transparent, often with a swollen, knee-like look at the nodes. Crushed stems release a watery, mucilaginous sap.

Flowers & Fruit

The flowers are the showstopper: orange (sometimes pale yellow), about 1 inch long, trumpet-shaped, and hanging horizontally like tiny lanterns. Each has a hooked spur at the back holding nectar that attracts hummingbirds and bees. Blooming runs summer into early fall (July-September). The fruit is a plump green capsule that, when ripe, explodes at the lightest touch, flinging seeds several feet, hence "touch-me-not." Testing a ripe pod with a fingertip is itself a near-certain ID confirmation.

How to Tell It Apart from Look-Alikes

• Pale Jewelweed (Impatiens pallida): nearly identical structure but yellow flowers with fewer or no spots and a shorter, more downward-bent spur. The two often grow together.
• Garden Impatiens / Touch-me-nots: cultivated relatives with flat, non-spurred or differently shaped flowers and usually upright blooms.
• Other wetland herbs lack the combination of translucent juicy stems + spurred dangling flowers + exploding pods, which together are diagnostic.

Where You'll Find It

Jewelweed loves moist, shady, low ground: stream banks, ditch edges, seeps, floodplain woods, pond margins, and damp roadside swales. It frequently grows in large colonies, often alongside stinging nettle and poison ivy in the same damp habitats.

Quick ID Checklist

• Dangling orange (or yellow) spotted flowers with a curled spur
• Translucent, hollow, watery stems that snap easily
• Oval, scalloped-toothed alternate leaves
• Ripe seed pods explode when touched
• Wet, shady habitat, often in dense stands
• Blooms midsummer to early fall
