Hedychium is a genus of flowering plants in the ginger family Zingiberaceae, native to lightly wooded habitats in Asia. There are approximately 70-80 known species, native to India, Southeast Asia, and Madagascar. Some species have become widely naturalized in other lands, and considered invasive in some places. [1] [2]

Contents

The genus name Hedychium is derived from two ancient Greek words, hedys meaning "sweet" and chios meaning "snow". This refers to the fragrant white flower of the type species H. coronarium . [3] Common names include garland flower, ginger lily, and kahili ginger.

Members of the genus Hedychium are rhizomatous perennials, commonly growing 120–180 cm (47–71 in) tall. Some species are cultivated for their exotic foliage and fragrant spikes of flowers in shades of white, yellow and orange. [4] Numerous cultivars have been developed for garden use, of which 'Tara' has gained the Royal Horticultural Society's Award of Garden Merit. [5] [6] Though reasonably hardy down to −10 °C (14 °F), it requires a sheltered position and a deep mulch in winter.

Species

Taxonomy and phylogeny

In 2000, Tom Wood et al. published the first phylogeny of the genus Hedychium represented by 29 taxa. [7]

Reproductive biology

Hedychium has multiple modes of reproduction: sexual, via rhizomes and via bulbils. Some species of Hedychium are reported to exhibit facultative vivipary. [8]

<span class="mw-page-title-main">Zingiberaceae</span> Family of plants

Zingiberaceae or the ginger family is a family of flowering plants made up of about 50 genera with a total of about 1600 known species of aromatic perennial herbs with creeping horizontal or tuberous rhizomes distributed throughout tropical Africa, Asia, and the Americas. Many of the family's species are important ornamental, spice, or medicinal plants. Ornamental genera include the shell gingers (Alpinia), Siam or summer tulip, Globba, ginger lily (Hedychium), Kaempferia, torch-ginger Etlingera elatior, Renealmia, and ginger (Zingiber). Spices include ginger (Zingiber), galangal or Thai ginger, melegueta pepper, myoga, korarima, turmeric (Curcuma), and cardamom.

<i>Lilium</i> Genus of plants

Lilium is a genus of herbaceous flowering plants growing from bulbs, all with large prominent flowers. They are the true lilies. Lilies are a group of flowering plants which are important in culture and literature in much of the world. Most species are native to the Northern Hemisphere and their range is temperate climates and extends into the subtropics. Many other plants have "lily" in their common names, but do not belong to the same genus and are therefore not true lilies.

<i>Iris</i> (plant) Genus of flowering plants in the family Iridaceae

Iris is a flowering plant genus of 310 accepted species with showy flowers. As well as being the scientific name, iris is also widely used as a common name for all Iris species, as well as some belonging to other closely related genera. A common name for some species is flags, while the plants of the subgenus Scorpiris are widely known as junos, particularly in horticulture. It is a popular garden flower.

<span class="mw-page-title-main">Daylily</span> Genus of flowering plants

A daylily or day lily is a flowering plant in the genus Hemerocallis, a member of the family Asphodelaceae, subfamily Hemerocallidoideae, native to Asia. Despite the common name, it is not in fact a lily. Gardening enthusiasts and horticulturists have long bred daylily species for their attractive flowers. Thousands of cultivars have been registered by local and international Hemerocallis societies. Daylilies are perennial plants, whose name alludes to its flowers, which typically last about a day.

<i>Agapanthus</i> Genus of flowering plants in the family Amaryllidaceae

Agapanthus is a genus of plants, the only one in the subfamily Agapanthoideae of the family Amaryllidaceae. The family is in the monocot order Asparagales. The name is derived from Greek: ἀγάπη, ἄνθος.

<i>Alstroemeria</i> Genus of South American flowering plants

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.

<i>Phalaenopsis</i> Genus of orchids

Phalaenopsis, also known as moth orchids, is a genus of about seventy species of plants in the family Orchidaceae. Orchids in this genus are monopodial epiphytes or lithophytes with long, coarse roots, short, leafy stems and long-lasting, flat flowers arranged in a flowering stem that often branches near the end. Orchids in this genus are native to India, Taiwan, China, Southeast Asia, New Guinea and Australia with the majority in Indonesia and the Philippines.

<i>Nymphaea</i> Genus of aquatic plants

Nymphaea is a genus of hardy and tender aquatic plants in the family Nymphaeaceae. The genus has a cosmopolitan distribution. Many species are cultivated as ornamental plants, and many cultivars have been bred. Some taxa occur as introduced species where they are not native, and some are weeds. Plants of the genus are known commonly as water lilies, or waterlilies in the United Kingdom. The genus name is from the Greek νυμφαία, nymphaia and the Latin nymphaea, which mean "water lily" and were inspired by the nymphs of Greek and Latin mythology.

<i>Hosta</i> Genus of flowering plants in the family Asparagaceae

Hosta is a genus of plants commonly known as hostas, plantain lilies and occasionally by the Japanese name gibōshi. Hostas are widely cultivated as shade-tolerant foliage plants. The genus is currently placed in the family Asparagaceae, subfamily Agavoideae, and is native to northeast Asia. Like many "lilioid monocots", the genus was once classified in the Liliaceae. The genus was named by Austrian botanist Leopold Trattinnick in 1812, in honor of the Austrian botanist Nicholas Thomas Host. In 1817, the generic name Funkia was used by German botanist Kurt Sprengel in honor of Heinrich Christian Funck, a collector of ferns and alpines; this was later used as a common name and can be found in some older literature.

<i>Roscoea</i> Genus of flowering plants

Roscoea is a genus of perennial plants of the family Zingiberaceae. Most members of the family are tropical, whereas Roscoea species are native to mountainous regions of the Himalayas, China and its southern neighbours. Roscoea flowers superficially resemble orchids, although they are not related. The flowers of Roscoea have a complicated structure, in which some of the showy coloured parts are not formed by petals, but by staminodes, sterile stamens which have evolved to become like petals. Some species are grown as ornamental plants in gardens.

<i>Cautleya</i> Genus of flowering plants

Cautleya is a small genus of perennial plants of the family Zingiberaceae, found in the eastern Himalayas through to China and Vietnam. It consists of two species of high-altitude tropical and temperate plants, native to cool forest areas – an unusual habitat for members of the Zingiberaceae. They are grown as ornamental flowering plants.

<i>Roscoea cautleyoides</i> Species of flowering plant

Roscoea cautleyoides is a perennial herbaceous plant occurring in the Sichuan and Yunnan provinces of China. The scientific name is also spelt Roscoea cautleoides. Most members of the ginger family (Zingiberaceae), to which it belongs, are tropical, but R. cautleyoides, like other species of Roscoea, grows in much colder mountainous regions. It is sometimes grown as an ornamental plant in gardens.

<i>Roscoea wardii</i> Species of flowering plant

Roscoea wardii is a perennial herbaceous plant occurring from eastern Arunachal Pradesh in India to western Yunnan in China. Most members of the ginger family (Zingiberaceae), to which it belongs, are tropical, but like other species of Roscoea, R. wardii grows in much colder mountainous regions.

Rosemary Margaret Smith (1933–2004) was a Scottish botanist and illustrator who specialized in the taxonomy of the Zingiberaceae, or ginger family. Many of the species she classified and identified as being placed into improper genera were found in Asian countries, especially in the isolated island of Borneo.
