About plant names...

False nettle is a native North American species. The name comes from is resemblance to stinging nettle, although it is not related, and lacks the stinging hairs of its namesake.

Plants: 4-63" (10-160 cm) high, and favor shady wooded areas. Stems are smooth, without the irritating hairs of stinging nettle.

Leaves: Usually opposite or nearly so. They are roughly egg-shaped, with sharp tips and teeth. (More precisely, they are elliptic, lanceolate to broadly ovate.) The leaves are 1¾-7" (5-18 cm) × ¾-4" (2-10 cm).

Flowers: The unusual flowers are the most unique feature of this species. They occur on straight spikes that emerge from the stem, in clusters of small, inconspicuous green flowers. Each spike is often tipped by a couple of small leaves. Flowers appear from July to August. The flowers are dioecious—each plant contains only male or female flowers.

Fruits: Spiky little balls.

Three-seeded Mercury
Plant 24-48" (60-121 cm) high. Stems have stiff white hairs that sting if you rub against them. 4-63" (10-160 cm) high, and favor shady wooded areas. Stems are smooth, without the irritating hairs of stinging nettle. 6-24" (15-60 cm) tall, with a stem that is hairless or covered with fine white hairs. Bracts beneath flowers, stems, and leaf undersides turn copper-colored.
Flowers Male flower clusters are white or greenish white, in loose branching clusters. Each flower is less than ⅛" (3.2 mm) across, with 5 petals. They appear from July to September. Flowers occur on straight spikes that emerge from the stem, in clusters of small, inconspicuous green flowers. Each spike is often tipped by a couple of small leaves. Flowers appear from July to August. Flowers are greenish-tan, and tiny—less than ⅛" (3.2 mm) across. They flower from July to October.
Leaves Alternate, up to 4" (10 cm) × 6" (15 cm), egg-shaped, with coarse serrations. Usually opposite or nearly so. They are roughly egg-shaped, with sharp tips and teeth. (More precisely, they are elliptic, lanceolate to broadly ovate.) The leaves are 1¾-7" (5-18 cm) × ¾-4" (2-10 cm). Leaves are alternate, lance-like or oval with sharp tips, 3½" (8.9 cm) × 1" (2.5 cm), with blunt serrations.
Fruit Oblique dry seeds. Spiky little balls. A 3-lobed roughly spherical fruit containing 3 seeds.

Stinging Nettle
Plant 6-24" (15-60 cm) high, with smooth, round, translucent stems. They do not have stinging hairs. 24-39" (60-100 cm) high, rarely up to twice that. The entire plant is covered in stinging hairs.
Flowers Both male and female flowers are on each plant. Fowers are ⅛" (3.2 mm) long, greenish-white or greenish-yellow, hanging in narrow bunches from the axils of the upper leaves. Plants are monoecious—male staminate flowers appear on the same plants as female pistillate flowers. Male flowers are grayish yellow, with four tepals. Female flowers have four tepals too, but in different-sized pairs. They are gray-green and hairy. The flower clusters resemble catkins.
Leaves Leaves occur in opposite pairs, each 1-5" (2.5-12 cm) long by ½-2½" (1.3-6.3 cm) wide. Leaves are oval-shaped and coarse-toothed, with three prominent veins and textured leaves. The leaves are bright green, usually shiny, and become yellow in the fall. Opposite, oblong, cordate, and serrate (with sawtooth edges). They are 1-6" (3-15 cm) long.
Fruit Tiny green seeds (achenes) sometimes have black stripes. Each inner pair of tepals encloses a single deltoid to ovoid seed.
Range/ Zones

Habitats Wet upland or floodplain forests, crevices in rocky canyons, and shady wetlands, streambanks. River deltas, floodplains, margins of deciduous woodlands, fencerows, and waste places
Type Wild Wild
