Bloom Time: May to September
Urtica dioica is a dioecious herbaceous perennial with a straight stem up to 5 feet (1.5 m) tall. The leaves are heart-shaped, up to 6 inches (15 cm) long. The leaves and stems are very hairy with non-stinging hairs. Flowers are very small, greenish, sometimes tinged pinkish, inconspicuous, up to 0.08 inches (2 mm) long, with 4 tiny sepals and no petals. Individual flowers are either male or female, but only one sex is to be found on any one plant so both male and female plants must be grown if seed is required.
How to Grow and Care
Nettles prefer rich soil with good moisture content and especially favors the edges of streams or nutrient-dense pastures.
Nettle seeds are tiny, light dependant germinators that can be started indoors or out. However, select your location carefully as Nettles are very hardy and can spread quickly with the right conditions. Nettle can be assisted with stratification, but it is not necessary.
To start, tamp the small seeds lightly into the soil or cover with a thin layer of soil (0.25 inch/6 mm). If starting indoors, sow in flats in late winter and transplant in early spring. Space plants approximately 8 inches (20 cm) apart.
If direct sowing, seed in spring and thin as desired and plant rows 1 inch (2.5 cm) apart. It recommended to find a permanent spot with rich, moist conditions a little away from (or on the periphery of) your other herbs… – See more at: How to Grow and Care for Stinging Nettle.
