Physostegia virginiana (L.) Benth. | |
Physostegia virginiana, the obedient plant, obedience or false dragonhead, [2] is a species of flowering plant in the mint family, Lamiaceae. It is native to North America, where it is distributed from eastern Canada to northern Mexico. [2] Physostegia are known commonly as obedient plants because a flower pushed to one side will often stay in that position. [3] The name “false dragonhead” refers to the dragonheads of the related Dracocephalum , [3] a genus to which the plant once belonged. [1]
It is a rhizomatous herbaceous perennial producing clumps of stiff, squared stems 2–4 ft (0.61–1.22 m) tall. The leaves are lanceolate and toothed. The inflorescence is a long, dense raceme containing many tubular pink flowers which resemble snapdragons. The open fruit is shaped like a vase and contains four triangular, black seeds.
There are two recognized subspecies. They are:
Cultivars of P. virginiana often do not fit well into either of the two varieties and are intermediate in characters. They are thought to have originated from hybridization between the two subspecies. [5] [6]
It is considered a good plant for adding late-season flowers to a garden. Fertile soils produce robust growth and wide spreading, and the plant may require staking. When it grows tall it has a "tendency toward floppiness" that can be controlled with pruning. It can be aggressive and dominate a landscape. [3]
Several cultivars have been bred for color variety. [7] Some (agm) have earned the Royal Horticultural Society's Award of Garden Merit. [8]
Cultivars include.
Epilobium canum, also known as California fuchsia or Zauschneria, is a species of willowherb in the evening primrose family (Onagraceae). It is native to dry slopes and in chaparral of western North America, especially California. It is a perennial plant, notable for the profusion of bright scarlet flowers in late summer and autumn.
Alstroemeria, commonly called the Peruvian lily or lily of the Incas, is a genus of flowering plants in the family Alstroemeriaceae. They are all native to South America, although some have become naturalized in the United States, Mexico, Australia, New Zealand, Madeira and the Canary Islands. Almost all of the species are restricted to one of two distinct centers of diversity; one in central Chile, the other in eastern Brazil. Species of Alstroemeria from Chile are winter-growing plants, while those of Brazil are summer growing. All are long-lived perennials except A. graminea, a diminutive annual from the Atacama Desert of Chile.
Osteospermum, is a genus of flowering plants belonging to the Calenduleae, one of the smaller tribes of the sunflower/daisy family Asteraceae. They are known as the daisybushes or African daisies.
Dasiphora fruticosa is a species of hardy deciduous flowering shrub in the family Rosaceae, native to the cool temperate and subarctic regions of the northern hemisphere, often growing at high altitudes in mountains. Dasiphora fruticosa is still widely referenced in the horticultural literature under its synonym Potentilla fruticosa. Common names include shrubby cinquefoil, golden hardhack, bush cinquefoil, shrubby five-finger, widdy, and kuril tea.
Lavandula stoechas, the Spanish lavender or topped lavender (U.S.) or French lavender (U.K.), is a species of flowering plant in the family Lamiaceae, occurring natively in several Mediterranean countries, including France, Spain, Portugal, Italy, Turkey and Greece.
Lavandula angustifolia, formerly L. officinalis, is a flowering plant in the family Lamiaceae, native to the Mediterranean. Its common names include lavender, true lavender and English lavender ; also garden lavender, common lavender and narrow-leaved lavender.
Cyperus alternifolius, the umbrella papyrus, umbrella sedge or umbrella palm, is a grass-like plant in the very large genus Cyperus of the sedge family Cyperaceae. The plant is native to West Africa, Madagascar and the Arabian Peninsula, but widely distributed throughout the world. It has gained the Royal Horticultural Society's Award of Garden Merit. The subspecies Cyperus alternifolius ssp. flabelliformis is also known as Cyperus involucratusRottb..
Fuchsia magellanica, commonly known as the hummingbird fuchsia or hardy fuchsia, is a species of flowering plant in the evening primrose family Onagraceae, native to the lower Southern Cone of southern South America.
Dicentra formosa is a flowering plant with fern-like leaves and an inflorescence of drooping pink, purple, yellow or cream flowers native to the Pacific Coast of North America.
Physostegia, the lionshearts or false dragonheads, is a genus of flowering plants in the family Lamiaceae, native to North America. They are erect rhizomatous herbaceous perennials inhabiting damp, sunny places. They grow up to 2 m (7 ft) tall with purple or pink tubular flowers in racemes in summer.
Romneya coulteri, the Coulter's Matilija poppy or California tree poppy, is a perennial species of flowering plant in the poppy family Papaveraceae. Native to southern California, USA, and Baja California, Mexico, it grows in dry canyons in chaparral and coastal sage scrub plant communities, sometimes in areas recently burned. It is a popular ornamental plant, kept for its large, showy flowers.
Symphyotrichum ericoides, known as white heath aster, frost aster, or heath aster, is a species of flowering plant in the family Asteraceae native to much of central and eastern North America. It has been introduced to parts of Europe and western Asia.
Iris pallida, the Dalmatian iris or sweet iris, is a hardy flowering perennial plant of the genus Iris, family Iridaceae. It is native to the Dalmatian coast (Croatia) but widely naturalised elsewhere. It is a member of the subgenus Iris, meaning that it is a bearded iris, and grows from a rhizome.
Hydrangea aspera is a species of flowering plant in the family Hydrangeaceae, native to the region between the Himalayas, across southern China, to Taiwan. It is a large, erect deciduous shrub growing to 3 m (10 ft) tall and wide, with broadly oval leaves. The flowers are typically borne in large flat heads in late summer, and are in variable shades of pale blue and pink, fringed by white or pale pink sterile florets.
Crocus chrysanthus, the snow crocus or golden crocus, is a species of flowering plant of the Crocus genus in the family Iridaceae. Native to the Balkans and Turkey, it bears vivid orange-yellow bowl-shaped flowers. It has smaller corms and a smaller flower than the giant Dutch crocus, although it produces more flowers per corm than the latter. Its common name, "snow crocus", derives from its exceptionally early flowering period, blooming about two weeks before the giant crocus, and often emerging through the snow in late winter or early spring. The leaves are narrow with a silver central stripe. Height: 3–4 inches (7.6–10.2 cm).
Crocus sieberi, Sieber's crocus, also referred to as the Cretan crocus or snow crocus, is a plant of the genus Crocus in the family Iridaceae. A small, early blooming crocus, it easily naturalises, and is marked by a brilliant orange which is mostly confined to the stamens and style, fading through the bottom third of the tepal. It grows wild generally in the Balkans and Greece, especially in the island Crete. There are four subtypes: sieberi (Crete), atticus, nivalis and sublimis. Its cultivars are used as ornamental plants. Height: 3–4 inches (7.6–10.2 cm).
