Spiranthes odorata | |
Spiranthes odorata, marsh lady's tresses [1] or common lady's tresses, [2] is a species of flowering plant in the orchid family, native to the southeastern United States, from Texas eastwards and northwards to Delaware. [1] It grows in moist, partially shaded environments with acidic or neutral soil.
An herbaceous perennial, this orchid grows up to 50 cm (20 in) tall and broad. The flowers are borne in dense vertical rows on sturdy green spikes, in a slightly twisted pattern (hence Spiranthes, "twisted flower"). This effect is due to uneven cell growth. The flowers, which appear in late summer and autumn, are white, hooded and fragrant (hence the specific epithet odorata).
This plant is pollinated by bumblebees, notably Bombus pensylvanicus , Bombus fervidus , Bombus impatiens , and Bombus nevadensis . [3]
In the UK, the cultivar ‘Chadd’s Ford’ has gained the Royal Horticultural Society’s Award of Garden Merit. [4] [5] Requiring a fertile soil in partial shade, it is hardy down to −10 °C (14 °F), but in frosty areas needs a dry mulch during the winter months.
Lapageria is a genus of flowering plants with only one known species, Lapageria rosea, commonly known as Chilean bellflower or copihue. Lapageria rosea is the national flower of Chile. It grows in forests in the southern part of Chile, being part of the Valdivian temperate rain forests flora.
Lamprocapnos spectabilis, bleeding heart or Asian bleeding-heart, is a species of flowering plant in the poppy family Papaveraceae, native to Siberia, northern China, Korea and Japan. It is the sole species in the monotypic genus Lamprocapnos, but is still widely referenced under its old name Dicentra spectabilis. It is valued in gardens and in floristry for its heart-shaped pink and white flowers, borne in spring.
Spiranthes is a genus of orchids in the subfamily Orchidoideae. They are known commonly as ladies tresses, ladies'-tresses, or lady's tresses. The genus is distributed in the Americas, Eurasia, and Australia. The genus name Spiranthes is derived from the Greek speira ("coil") and anthos ("flower"), and was inspired by the spirally arranged inflorescence.
Cypripedium acaule is a species of flowering plant in the orchid family Orchidaceae. The genus Cypripedium is one of the five genera in the sub-family Cypripedioideae, commonly known as lady's slipper orchids. First described in 1789 by Scottish botanist William Aiton, C. acaule is commonly referred to as the pink lady's slipper, stemless lady's-slipper, or moccasin flower. The pink lady's slipper is the provincial flower of Prince Edward Island, Canada, and the state wildflower of New Hampshire, United States. Its close relative, Cypripedium reginae, is the state flower of Minnesota.
Spiranthes spiralis, commonly known as autumn lady's-tresses, is an orchid that grows in Europe and adjacent North Africa and Asia. It is a small grey-green plant. It forms a rosette of four to five pointed, sessile, ovate leaves about 3 cm (1.2 in) in length. In late summer an unbranched stem of about 10–15 cm (3.9–5.9 in) tall is produced with approximately four sheath-shaped leaves. The white flowers are about 5 mm (0.20 in) long and have a green spot on the lower lip. They are arranged in a helix around the upper half of the stalk. The species is listed in Appendix II of CITES as a species that is not currently threatened with extinction but that may become so. Autumn lady's-tresses are legally protected in Belgium and the Netherlands.
Goodyera, commonly called rattlesnake plantain, jade orchids or ladies' tresses is a wide-ranging genus of orchids in the tribe Cranichideae. About 100 species of Goodyera have been formally described. They are native to Europe, Madeira, Mozambique, North and Central America, islands from the west Indian Ocean to the Pacific Ocean and to Australia. They have a rosette of leaves at their base and usually many small white resupinate flowers. They are similar to orchids in the genus Spiranthes but can be distinguished from them by the shape and colour patterns of the leaves.
