Yellow Dead Nettle Lamium galeobdolon


Yellow Archangel (Lamium galeobdolon)

A European plant often cultivated here as a ground cover, but increasingly escaping into the wild. This plant was growing deep in the woods in Fox Chapel, on a hillside overlooking the Squaw Run, far from any cultivated planting. It is also commonly placed in the genus Lamiastrum, or “False Lamium.” So it is classified in the USDA PLANTS database, which records it as found in the wild in Pennsylvania. This particular plant, which shows the variegated leaves often found in cultivated varieties, was blooming in early May.

Gray describes the genus Lamium thus:

LAMIUM L. DEAD NETTLE. Calyx tubular-bell-shaped, about 5-nerved, with 5 nearly equal awl-pointed teeth. Corolla dilated at the throat; upper lip ovate or oblong, arched, narrowed at the base; the middle lobe of the spreading lower lip broad, notched at the apex, contracted as if stalked at the base; the lateral ones small, at the margin of the throat. Decumbent herbs, the lowest leaves small and long-petioled, the middle heart-shaped and doubly toothed, the floral subtending the whorled flower-cluster. (Name from lamos, throat, in allusion to the ringent corolla.)

This species is not described in the standard American botanical references, so we borrow a very thorough description from English Botany by James Sowerby.


Galeobdolon luteum, Ends. Sm. Engl. Bot. ed. i. No. 787. Koch, Syn. Fl. Germ. et Helv. ed. ii. p. 650. Galeopsis Galeobdolon, Linn. Sp. Pl. p. 810.

Perennial. Rootstock tufted or very shortly creeping. Barren shoots very long, trailing or arching, at length rooting. Flowering stems not rooting at the base, erect or ascending. Leaves stalked, ovate or deltoid-ovate, subcordate, slightly acuminate, acute, doubly or irregularly crenate-serrate. Verticillasters remote from each other. Lower bracts similar to the leaves, but narrower, and with shorter stalks; upper ones generally lanceolate, with a wedge-shaped base, more rarely similar to the lower ones. Calyx puberulent or sparingly bristly-hairy; teeth deltoid, abruptly acuminated into triangular points, sparingly ciliated or glabrous, and subspinous at the apex, spreading, not half the length of the tube; tube slightly curved and oblique at the mouth. Corolla tube rather longer than the calyx, with a conspicuous very oblique ring of hairs within, slightly curved upwards, without a projecting sac near the base on the lower side, suddenly enlarged towards the apex; upper hp greatly vaulted, obtuse, sparingly hairy; lower lip with the lateral lobes ovate-acuminate, the middle lobe a little larger, oblong, acuminated into a lanceolate point.

Cannabis sativa is believed to be a native plant of India, where it possibly originated in a region just north of the Himalayan mountains. It's a herbaceous annual that can grow to a height of between 13 and 18 feet (4 to 5.4 meters). The plant has flowers that bloom from late summer to mid-fall. Cannabis plants usually have one of two types of flowers, male or female, and some plants have both. Male flowers grow in elongated clusters along the leaves and turn yellow and die after blossoming. Female flowers grow in spikelike clusters and remain dark green for a month after blossoming, until the seed ripens

DALY: Use care when planting around septic drainfields  —
Shallow rooted annual and perennial herbaceous plants can be planted closer to the drain fields since they do not have invasive roots. Turfgrass can be grown over the drain field and is beneficial since it helps hold the soil in place.
