POTTED PLANTS

The Potted Plants Gallery pays homage to the Conservatory’s late 1800’s Victorian roots when plant collectors stored their exotic tropical treasures in opulent glass greenhouses to protect them from cold European climates. Rare flowering plants are potted in an incredible assortment of decorative urns and containers from all over the world including copper containers from India, Javanese palm pots, ceramic pots from Burkina Faso and a historic urn from San Francisco’s 1915 Panama-Pacific International Exposition.

Acalypha hispida
Common Name: Chenille Plant
Family Name: Euphorbiaceae
Native to: New Guinea, Malaysia

The common name, chenille, means caterpillar in French. The fuzzy, pendulous inflorescence of the chenille plant range in color from vibrant red through a creamy white. The chenille plant is dioecious, meaning the male (staminate) and female (pistillate) flowers are on separate plants. The individual flowers which make up the inflorescence are very tiny, have no petals, and are made up of feathery pistils. These pistils are tightly packed into cylindrical flower clusters along the raceme called catkins. Flowers with catkins, including the chenille, are predominantly pollinated by the wind, and occasionally by insects.

Dioscorea mexicana
Common Name: Tortoise Plant, Mexican Yam
Family Name: Dioscoreaceae
Native to: Mexico, Panama, El Salvador

Dioscorea mexicana is a member of the Dioscorea genus which is composed of approximately 600 species, including several species of yams. D. mexicana’s native range spans from Veracruz, through Mexico and down to Panama. Dioscorea mexicana gets its common name, tortoise plant, from the caudex which resembles a tortoise shell with polygonal plates that are separated by deep fissures. The caudex is a modified stem that stores water and nutrients that help the plant adapt to dry conditions. Vigorous vines emerge from the top of the caudex and bear heart-shaped leaves. The tortoise plant is dioecious, meaning individual plants are either male or female.

Dioscorea mexicana plays an important medicinal role. The plant contains diosgenin, a steroid that is a precursor for the synthesis of hormones, including progesterone and cortisone. Traditionally, D. mexicana and other plants of this genus were used by natives as a natural birth control and as an ailment for sore joints. In the mid-1950s a chemist, Russell Marker, developed the synthesis process of progesterone from the naturally produced diosgenin in D. mexicana. This discovery led to the affordable production of birth control.

Ficus deltoidea
Common Name: Mistletoe Fig
Family Name: Moraceae
Native to: Southeast Asia

The mistletoe fig is a slow-growing tree native to the rainforests of Southeast Asia, widely naturalized in other parts of the world, and prominent in Malaysia for its medicinal properties. It is distinctive for its slender silver trunk, gray-green foliage that differs in shape depending on its sex (larger and rounder for females, smaller and oblong for males), and long aerial roots that hang down in tendrils. Ficus deltoidea’s nickname “mistletoe fig” comes from its small orange and red fruits, which resembles mistletoe berries.

The plant is also known as mas cotek in Malaysia and is recognized in both traditional and worldwide medicine for its healing and health benefits. Ongoing scientific research by various institutions including the Malaysian Agriculture Research and Development Institute (MARDI) shows that the plant possesses compounds that help lower glucose levels in diabetic patients, works as an antioxidant and maintains healthy blood circulation. Traditionally, mas cotek has been used for strengthening the uterus, regulating blood pressure and nervous system, reducing fatigue, and enhancing libido.

Globba
Common Name: Dancing Lady Ginger
Family Name: Zingiberaceae
Native to: China, India, Southeast Asia, New Guinea, Bismarck Archipelago, Queensland

Plants in the Globba genus are commonly known as the dancing lady ginger due to their yellow flowers that dangle and dance in the wind. This dance is likely performed to attract the plant’s pollinators. The purple petal-like structures are called bracts. Bracts are modified leaves that protect the flowers as they emerge and may also attract pollinators by providing a colorful backdrop for the flowers. A greatly elongated, arched stamen contains the plant’s pollen. Notice that the flowers are symmetrical when divided in half, much like a face or an orchid flower. Globbas are members of the ginger family, Zingiberaceae, and like all gingers, they grow from creeping rhizomes that form clumps underground.

Ixora coccinea
Common Name: Scarlet Jungle Flame, Flame of the Woods
Family Name: Rubiaceae
Native to: India, Sri Lanka, and Southeast Asia

Ixora coccinea, commonly known as scarlet jungle flame, is native to Southeast Asia, India, and Sri Lanka, but is widely grown in tropical areas as a popular ornamental shrub. Ixora coccinea is a dense multi-branching evergreen shrub that is notable for its brightly colored blooms. The scarlet, tubular flowers grow in dense rounded clusters and can bloom year-round in the right conditions. Ixora coccinea is a member of the Rubiaceae family and is a showy relative of coffee. The genus name Ixora is a Portuguese translation of Isvara meaning ‘lord’ in Sanskrit and is a reference to the god Siva. The species name coccinea translates to scarlet and is a reference to the blooms. 

Phalaenopsis
Common Name: Moth Orchid
Family Name: Orchidaceae
Native to: India, China, Korea, Japan, Thailand, Indochina, Malaysia, Indonesia, Philippines, Australia, New Guinea

Phalaenopsis orchids are perhaps the most easily recognizable orchids and the most popular orchid genus in cultivation. The genus is composed of approximately 40-50 species that grow natively across Southeast Asia from the Himalayan Mountains to Australian. Phalaenopsis thrives in three distinct habitats: seasonally dry, seasonally cool, and constantly humid and warm.

Phalaenopsis orchids produce a large spray of flowers that can bloom for several weeks. There is a great diversity of color between species with flowers showing spotted, marbled, or barred color patterns. The shape of the flower is thought to resemble moths in flight, which contribute to the common name the moth orchid. The beautiful blooms and hardiness, in combination with the ease of hybridization, have contributed to their success as popular houseplants. Phalaenopsis orchids were some of the first tropical orchids in Victorian collections.

Sarracenia
Common Name: North American Pitcher Plants
Family Name: Sarraceniaceae
Native to: Southeastern United States to Southern Canada

Sarracenia is a genus comprising of about 10 species of North American pitcher plants. Like the more famous Venus flytrap, these plants are carnivorous. But unlike the fly trap, which moves to trap its prey, the Sarracenia has a passive trap. The plant’s leaves have evolved into a funnel-shaped pitcher. Insects are attracted by a nectar-like secretion on the lip of pitcher, as well as a combination of color and scent. Slippery footing at the pitchers’ rim causes the insect to fall in. Once inside, tiny downward-facing hairs make it nearly impossible for an insect to crawl back out, and liquids at the bottom of the pitcher make tiny wings too wet to fly.

Sarracenia are often found in hot, sunny bogs of Texas and the east coast of the United States. Bog soil is acidic and lacks nutrients so digested insects serve as an important source of nourishment for the plants. When blooming, the Sarracinia’s dramatic umbrella-like flowers are usually on long stems well above the pitcher, to avoid trapping potential pollinators.
