Circaea lutetiana, known as broad-leaved enchanter's nightshade, [1] is a plant in the evening primrose family, Onagraceae.
The genus name comes from the enchantress Circe of Greek mythology and the specific designation is derived from Lutetia, the Latin name for Paris, which was sometimes referred to as the "Witch City". Despite its name it is not especially toxic, but contains a lot of the astringent tannin. [2]
Circaea lutetiana is a perennial herbaceous plant with opposite, simple leaves, on slender, green stems. The flowers are white, borne in summer. It grows 20 cm to 60 cm, rarely up to 75 centimeters high. [3]
The leaves are rounded or slightly notched at the base, they narrow gradually to the pointed tip and are not strongly toothed, but have sinuate edges. The leaf stalks are equally hairy all round. [4]
The flower has 2 notched petals, 2 stamens and a 2-lobed stigma. The open flowers are well spaced along the stalk and there are no bracts at base of individual flower stalks. The fruit consists of 2 equal cells, and usually sets seed. The flower stalks become angled downwards before fruiting. [5] The fruit is a small bur 3.5-5mm [6] which aids the plant's dispersal via zoochory.
In winter the aerial parts die off leaving an underground rhizome.
Circaea alpina will hybridize with Circaea lutetiana producing sterile offspring that persists in vegetative colonies. [6]
The plant is native to Europe, Middle Asia, and Siberia. [7] North American populations are now considered to be a separate species, Circaea canadensis . It grows in woods in deep shade and moist environments on nitrogen-containing clay.
It is cultivated as an ornamental garden plant. It prefers a shaded position in rich, moist soil. [8] The cultivar 'Caveat Emptor' has leaves that are heavily mottled pink.
Abutilon pictum, syn. Abutilon striatum (disputed), is a species of flowering plant in the family Malvaceae. It is native to southern Brazil, Argentina, Paraguay and Uruguay. The plant has become naturalised in Central America, and is used in horticulture. Common names include redvein abutilon, red vein Indian mallow, redvein flowering maple, Chinese-lantern and red vein Chinese lanterns.
The Circaea, or enchanter's nightshades, are a genus of flowering plants in the evening primrose family Onagraceae. About two dozen taxa have been described, including eight species. Plants of the genus occur throughout the temperate and boreal forests of the Northern Hemisphere. Three taxa occur in North America: Circaea alpina, Circaea canadensis, and the hybrid Circaea × sterilis. The generic name Circaea refers to the enchantress Circe from Greek mythology who is said to have used the herb as a charm.
Pulmonaria longifolia, is a semi-evergreen clump-forming herbaceous perennial plant, native to western Europe, including Britain, France, Spain, Portugal. It grows in semi-shaded habitats, such as woodland and scrub, to 2000 m above sea level.
A bur is a seed or dry fruit or infructescence that has hooks or teeth. The main function of the bur is to spread the seeds of the bur plant, often through epizoochory. The hooks of the bur are used to catch on to for example fur or fabric, so that the bur, which contain seeds, then can be transported along with the thing it attached itself to. Another use for the spines and hooks are physical protection against herbivores. Their ability to stick to animals and fabrics has shaped their reputation as bothersome.
Mitella diphylla is a clump forming, open woodland plant native to northeast and midwest regions of North America.
Cephalotaxus harringtonia, commonly known as Japanese plum-yew, Harrington's cephalotaxus, or cowtail pine, is a coniferous bush or small tree in the family Taxaceae. It is native to Japan, but is occasionally utilised in western gardens and several cultivars exist for these purposes. Japanese plum yew has been in cultivation in Europe since 1829, and many modern horticulturists are familiar with this Japanese species, named in honor of Charles Stanhope, 4th Earl of Harrington, one of the first to grow the plant in a European garden, at Elvaston.
Stachys sylvatica, commonly known as hedge woundwort, whitespot, or sometimes as hedge nettle, is a perennial herbaceous plant growing to 80 cm (31 in) tall in woodland and unmanaged grassland. In temperate zones of the northern hemisphere it flowers in July and August. The flowers are purple. The leaves, when crushed or bruised, give off an unpleasant fetid smell.
Ligularia dentata, the summer ragwort or leopardplant, is a species of flowering plant in the genus Ligularia and the family Asteraceae, native to China and Japan.
Lathyrus palustris is a species of wild pea known by the common name marsh pea. It is native to Europe, Asia, and North America. It is a perennial herb with leaves made up of oval-shaped or oblong leaflets a few centimeters long. It has branched, coiled tendrils. The plant bears an inflorescence of two to eight pinkish purple pea flowers each up to two centimeters wide. The fruit is a dehiscent legume pod.
Lonicera tatarica is a species of honeysuckle known by the common name Tatarian honeysuckle. Native to Eurasia, the plant is one of several exotic bush honeysuckles present in North America, being considered an invasive species there.
Potentilla norvegica is a species of cinquefoil known by the common names rough cinquefoil, ternate-leaved cinquefoil, and Norwegian cinquefoil. It is native to Europe, Asia, and parts of North America, and it can be found elsewhere as an introduced species.
Anemonoides blanda, syn. Anemone blanda, the Balkan anemone, Grecian windflower, or winter windflower, is a species of flowering plant in the family Ranunculaceae. The species is native to southeastern Europe and the Middle East. The specific epithet blanda means "mild" or "charming". The genus name is derived from the Greek word anemos, or wind.
Bergenia crassifolia is a species of flowering plant of the genus Bergenia in the family Saxifragaceae. Common names for the species include heart-leaved bergenia, heartleaf bergenia, leather bergenia, winter-blooming bergenia, elephant-ears, elephant's ears, Korean elephant-ear, badan, pigsqueak, Siberian tea, and Mongolian tea.
Mompha terminella is a moth in the family Momphidae found in Europe and North America.
Cyclachaena xanthiifolia, known as giant sumpweed, or rag sumpweed is a North American plant species in the sunflower family, Asteraceae. It is the only species in the genus Cyclachaena. Giant sumpweed is believed to be native to the Great Plains but is now found across much of southern Canada and the contiguous United States, though rarely in the Southeast.
Actaea elata is a species of flowering plant in the buttercup family known by the common name tall bugbane. It is native to the Pacific Northwest of North America, where it can be found in British Columbia, Washington, and Oregon.
Hesperocodon hederaceus, synonym Wahlenbergia hederacea, also known as the ivy-leaved bellflower, is a species of flowering plant that is found throughout Europe. It is the only species in the genus Hesperocodon. The delicate, patch-forming, hairless perennial herb has thin, creeping stems about 20 cm in length. Its pale green leaves are long-stalked and have an ivy-shaped, rounded structure. These leaves can be described as having a cordate shape and are approximately 5–12 mm long and wide. The plant has erect, solitary, pale blue flowers in summer and autumn, with bell-shaped corolla with 5 short lobes. The flowers are 6–10 mm long x 5–8 mm wide and sit on fine stalks 1–4 cm long. It is suggested that the long pedicels are an adaptation to assist in seed dispersal.
Circaea alpina, commonly called alpine enchanter's nightshade or small enchanter's nightshade, is a 10–30 cm tall perennial herb found in cool forests of the Northern Hemisphere.
Alternanthera brasiliana, also known as large purple alternanthera, metal weed, bloodleaf, parrot leaf, ruby leaf, Brazilian joyweed, purple alternanthera, purple joyweed, is a flowering plant of the amaranth family that is native to the forests of South America and as well as Central America. Grown as an ornamental plant, it is very similar in appearance to Alternanthera dentata, which is listed as one of this species's synonyms.
Circaea canadensis, known as eastern enchanter's nightshade, Canada enchanter's nightshade, broad-leaved enchanter's nightshade, is a perennial herbaceous plant found in forests of eastern North America. It is very similar to its sister species, Circaea lutetiana, and was formerly considered conspecific.
