Bulbous Adder's-tongue
Ophioglossum crotalophoroides
Ophioglossum crotalophoroides is a tiny primitive fern (2 to 10 cm tall), with a single oval sterile leaf and a bulbous underground base (rather than a common cylindrical rhizome). It produces an elongated fertile spike resembling a rattlesnake's rattle, the origin of the epithet "crotalophoroides". It is ephemeral, appearing in spring (sporulating from March to June in the Northern Hemisphere) and disappearing shortly after. It occurs in disturbed lawns, open fields, and sandy soils of the southeastern United States. Like the entire Ophioglossaceae family, it depends closely on soil mycorrhizal fungi to germinate and develop, making it virtually impossible to cultivate outside its natural habitat.
Dwarf Lilyturf
Ophiopogon
Ophiopogon is a genus of evergreen, grass-like perennials in the family Asparagaceae, native to East and Southeast Asia, with Ophiopogon japonicus as the most widely cultivated species. It forms dense clumps of thin, arching, linear leaves resembling a coarse turf grass, creating a uniform dark-green mat. It is widely used as a shade groundcover, border edging, and filler between stepping stones, precisely because it tolerates spots where regular lawn grass fails from lack of sun. In summer it produces small, understated white-to-pale-lilac flowers, followed by ornamental cobalt-blue berries.
White Lilyturf
Ophiopogon jaburan
White lilyturf (Ophiopogon jaburan) is an evergreen perennial native to Japan and southern Korea, prized as a shade-tolerant groundcover and border plant. It forms dense clumps of long, arching, strap-like leaves — plain green or variegated with cream stripes — and sends up spikes of small white to pale lavender flowers in summer, followed by ornamental violet-black berries in fall. Low-maintenance and adaptable, it handles partial shade to full coastal sun and light frost.
Mondo Grass
Ophiopogon japonicus
Ophiopogon japonicus, commonly known as mondo grass or dwarf lilyturf, is an evergreen perennial groundcover native to Japan and East Asia. It forms dense, low-growing mats of dark green, grass-like foliage and is widely used in shaded gardens. In summer it produces small white to pale lilac flowers followed by ornamental cobalt-blue berries.
Fly Orchid
Ophrys insectifera
Ophrys insectifera, commonly known as the fly orchid, is a European terrestrial species notable for its pollination strategy. Its flowers have evolved to visually and chemically mimic the females of certain wasp and fly species, tricking males into performing pseudocopulation, which ensures pollen transfer. It is a small plant with a rosette of basal leaves and a slender inflorescence.
Prickly Pear Cactus
Opuntia
Opuntia, commonly known as prickly pear or nopal, is a genus of cacti native to the Americas, especially Mexico. Its flattened pads (cladodes), spines, and showy flowers make it one of the most recognizable plants in the world. It produces edible fruits (tunas) and pads (nopales) that have been used in Mexican cuisine for millennia.
Sweet Prickly Pear
Opuntia dillenii
Opuntia dillenii, commonly known as the Sweet Prickly Pear, is a robust cactus native to the Caribbean and coastal Americas. Its oval, spine-covered pads produce vibrant yellow flowers in spring and summer, followed by edible reddish-purple fruits. Exceptionally drought-tolerant and heat-resistant, it thrives in poor, sandy soils with minimal care.
Prickly Pear
Opuntia ficus-indica
Opuntia ficus-indica, commonly known as prickly pear or Indian fig, is a large tree-like cactus native to Mexico. It features flattened stem segments called cladodes (pads) armed with clusters of tiny glochids. It produces showy yellow to orange-red flowers in spring and summer, followed by edible fruits called tunas or prickly pears. One of the most economically important cacti in the world.
Brittle Prickly Pear
Opuntia fragilis
Opuntia fragilis, known as the brittle prickly pear, is a low-growing, mat-forming cactus native to prairies and rocky outcrops across western North America, from British Columbia to Texas. It is the most cold-hardy cactus species in North America, surviving winter temperatures below -30 C. Its small, easily detached stem segments (cladodes) break off at the slightest touch and root readily wherever they land, giving the plant its "fragilis" name and its efficient means of vegetative spread.
Violet Prickly Pear
Opuntia gosseliniana
Opuntia gosseliniana is a shrubby prickly pear cactus native to the Sonoran Desert, from southern Arizona (Pima County) to Sonora, Chihuahua and Baja California, where it grows in desert scrub and grasslands at 700-1,600 m. Its rounded, flat pads are bluish-green and turn violet to deep purple in cold or dry weather. Long white to brownish spines appear mostly toward the pad edges, and with age it forms a short trunk. Bright yellow flowers open in spring (April-May), followed by purplish, spineless fruits. It usually reaches about 1-1.2 m tall and wide.
Eastern Prickly Pear
Opuntia humifusa
Opuntia humifusa, the Eastern Prickly Pear, is a low-growing, mat-forming cactus native to the eastern and central United States. It produces flat, paddle-shaped pads armed with glochids and occasional spines, stunning yellow flowers up to 4 inches wide in late spring and early summer, and edible red-purple fruits in late summer. One of the most cold-hardy cacti in the world, it thrives in USDA zones 4–9 and can survive temperatures as low as -12°C (10°F).
Aaron's Beard Cactus
Opuntia leucotricha
Opuntia leucotricha is a tree-like prickly pear from the Altiplano of central Mexico, growing a distinct trunk and a broad crown 3 to 5 m tall in the wild. Its grey-green pads are covered in a fine white fuzz, and the areoles carry flexible white spines that turn into long beard-like bristles on old trunks. In spring and summer it bears yellow flowers with a red style and green stigma lobes, followed by fragrant, edible white or red fruit.
Purple Pricklypear
Opuntia macrocentra
Opuntia macrocentra is a pad-forming cactus from the southwestern United States and northern Mexico, where it grows in desert grassland and scrub at 1000 to 1600 m. It forms low, trunkless clumps 60 to 90 cm tall and up to 1.8 m wide. The bluish-green pads turn purple or magenta in cold weather and drought, which gives the plant its name. Long dark spines grow mostly from the upper edges of the pads. In spring it bears large yellow flowers with a red center, followed by edible reddish-purple fruit.
Twistspine Pricklypear
Opuntia macrorhiza
Opuntia macrorhiza is a low-growing, mat-forming prickly pear cactus native to the central and southern United States and northern Mexico, from Colorado and Utah east to Wisconsin and Missouri and south into Texas. One of the most cold-hardy Opuntia species, it survives winters down to USDA zone 3a. Its flattened, blue-green pads (cladodes) are armed with twisted, often reflexed spines, and in early summer it produces bright yellow flowers with a red-orange eye, followed by fleshy edible fruit.
Bunny Ears Cactus
Opuntia microdasys
Native cactus from central and northern Mexico, known for its characteristic oval pads covered with white or yellow glochids that give it a velvety appearance. Forms dense bushes up to 60 cm tall and is highly valued as an ornamental plant both indoors and outdoors.
Angel's Wings Cactus
Opuntia microdasys var. albispina
Opuntia microdasys var. albispina is the white-tufted form of the bunny ears cactus, from central and northern Mexico. It has no true spines: its flat, oval green pads, 7.5 to 15 cm long, are dotted with tufts of white glochids, very fine barbed bristles that come off at the slightest touch and irritate the skin. In the common species these tufts are yellow. It forms a low clump 40 to 60 cm tall that can spread over 1 m wide in the ground and stays compact in a pot. Pale yellow flowers appear at the pad tips in late spring and summer, but they are rare in pots. It grows more slowly and is less cold hardy than the common bunny ears.
Drooping Prickly Pear
Opuntia monacantha
Opuntia monacantha, commonly known as the Drooping Prickly Pear, is a cactus native to South America (Brazil, Argentina, Uruguay, and Paraguay). It features flat, bright-green pads with yellow flowers and colorful edible fruits. A tough, drought-tolerant species, it thrives in full sun and well-draining sandy soil, making it an excellent choice for low-maintenance gardens and sunny interiors.
Prickly Pear
Opuntia orbiculata
Opuntia orbiculata is a paddle-type cactus belonging to the Cactaceae family, native to arid and semi-arid regions of the Americas. It forms shrubby clumps with flattened, succulent segments (pads) covered in glochids—tiny, fine, barbed spines that detach easily when touched. It is a hardy plant that grows in stacked segments, blooming in late spring and early summer with large, showy flowers followed by edible fruits (known as 'tunas').
Blind Prickly Pear
Opuntia rufida
Opuntia rufida is a shrubby, many-branched cactus native to the Chihuahuan Desert of Big Bend, Texas and northern Mexico. Its flattened, blue-green pads (cladodes) are spineless but densely covered in reddish-brown glochid clusters that give the plant its cinnamon-colored look and its common name, since livestock that brush against the glochids can be blinded. In summer it produces yellow flowers that fade to apricot or red, followed by reddish edible fruit.
Erect Prickly Pear
Opuntia stricta
Opuntia stricta is an upright to spreading succulent shrub from the Cactaceae family, native to tropical and subtropical America including Florida, Cuba, and eastern Mexico. Typically 50-100 cm tall but can reach 2 m in height. The plant bears flat, paddle-shaped stems (cladodes) 10-35 cm long covered in sharp spines and microscopic barbed glochids. It produces bright yellow flowers in spring and summer, followed by edible red or purple fruits. Now classified as one of the 100 worst invasive species globally, it has spread throughout Africa, Australia, Mediterranean regions, and Asia.
Woollyjoint Prickly Pear
Opuntia tomentosa
Opuntia tomentosa, the woollyjoint prickly pear, is a tree-forming cactus native to central Mexico's semi-arid highlands. Over years it develops a short, thick trunk topped with broad, velvety green pads covered in fine, felt-like hairs (hence 'tomentosa'), eventually reaching 3-6 m and occasionally up to 8 m in the wild. In spring and summer it bears yellow-to-orange, sometimes red-tinged flowers followed by sweet, edible reddish-purple fruit ('tunas'). Extremely drought tolerant once established, it thrives in full sun and sandy, fast-draining soil, and is grown both ornamentally and for its edible pads and fruit.
Tuna Prickly Pear
Opuntia tuna
Opuntia tuna, commonly known as tuna prickly pear or Caribbean prickly pear cactus, is a robust columnar cactus native to the Caribbean and tropical Americas. Its flattened pads (cladodes) are armed with spines and glochids, and it produces showy yellow-to-orange flowers in spring and summer, followed by edible reddish fruits.
Schweinfurth's Carrion Flower
Orbea schweinfurthii
Orbea schweinfurthii is a low, mat-forming succulent in the milkweed subfamily of the Apocynaceae, native to the savannas and rocky grasslands of eastern and southern Africa -- from Botswana and Namibia through Zimbabwe, Zambia, Malawi, the Democratic Republic of Congo, Tanzania, Rwanda and Uganda. Its leafless, four- to five-angled stems creep and branch along the ground, rarely exceeding 15 cm, with widely spaced tubercles that taper to a small conical tooth and often blush purple-red under strong sun or stress. In summer and autumn it produces star-shaped flowers with a deep yellow, densely papillate corolla marked with dark maroon spots and a cream corona flecked with purple. Unlike most of its carrion-flower relatives, its scent is mild and fruity rather than foul, resembling overripe orange, pineapple or red wine, and it draws small fruit flies rather than blowflies as pollinators.
Carrion Flower
Orbea variegata
Orbea variegata, commonly known as Carrion Flower or Starfish Plant, is a low-growing succulent native to the Cape Province of South Africa. It produces striking star-shaped flowers up to 8 cm across, yellow or off-white with dark maroon spots, that emit a carrion odor to attract fly pollinators.
Orchid
Orchidaceae
Orchidaceae is one of the largest families of flowering plants, with over 25,000 species of mostly epiphytic and terrestrial perennials prized for their intricate, long-lasting blooms. The Phalaenopsis, or moth orchid, is the most widely grown houseplant representative of the family, valued for its arching sprays of waxy flowers that can stay open for months. Most cultivated orchids are epiphytes native to tropical and subtropical forests, where they cling to tree bark and absorb moisture and nutrients through thick, exposed aerial roots rather than soil.
Early-purple orchid
Orchis mascula
Orchis mascula is a tuberous terrestrial orchid native to Europe, North Africa, and parts of Asia. It produces dense spikes of purple to pinkish flowers in the spring, rising above a rosette of leaves that are often spotted with dark purple. Unlike tropical orchids grown as houseplants, this is a wild species of woodlands and meadows that relies on a symbiotic soil fungus (mycorrhiza) to survive, making it notoriously difficult to cultivate outside its natural habitat. In many European countries, it is a protected wildflower and should never be removed from the wild.
Old Man of the Andes
Oreocereus celsianus
A slow-growing columnar cactus native to the Andes of Bolivia, Peru, and Argentina, where it grows at altitudes between 2,900 and 3,600 meters. Its upright stems, which branch at the base, are covered in dense white wool and long yellowish spines. They can reach up to 3 meters in height in the wild, though they rarely exceed 1 meter in cultivation. The white 'beard' covering the top of the stems protects the plant from intense solar radiation and the extreme temperature fluctuations of its high-altitude habitat, giving it its popular names. In spring, it produces tubular pinkish-purple flowers, usually pollinated by hummingbirds, followed by small globose fruits.
Old Man of the Andes
Oreocereus trollii
Oreocereus trollii is a woolly cactus from the high Andes of southern Bolivia and northern Argentina, where it grows on dry mountain slopes between about 2,900 and 4,300 m. It branches from the base into small clumps of short, thick stems 6-10 cm across. Young stems are almost round; older ones become columnar and can reach 1 m in the wild, though in pots they usually stay under 50 cm. Each stem has 15-25 low, knobbly ribs and is wrapped in dense white wool, which is really a mass of fine, hair-like radial spines up to 7 cm long. Through this wool push 3-5 stout central spines up to 5 cm long, in yellow, orange, red or brown with darker tips. The wool shields the plant from strong mountain sun and light night frosts. Mature plants produce pink to crimson, tube-shaped flowers up to 4 cm long in summer, followed by round fruits. It grows slowly and takes 5-10 years to reach full size.
Oregano
Origanum
Origanum is a genus of aromatic Mediterranean herbs in the Lamiaceae family, widely known for culinary and medicinal use.

Ornithogalum
Ornithogalum
Ornithogalum is a genus of about 200 bulbous plants in the asparagus family (Asparagaceae), native to Europe, the Mediterranean, western Asia and especially southern Africa. Each bulb produces a tuft of narrow, strap-shaped leaves and stems topped with clusters or spikes of star-shaped flowers, usually white with a green stripe on the back, and orange or yellow in some species. The most grown species are O. umbellatum (Star of Bethlehem, a hardy garden bulb), O. thyrsoides (chincherinchee, a long-lasting cut flower), O. dubium (sun star, sold as a pot plant) and O. arabicum; the care on this page is valid for them.
Sun Star
Ornithogalum dubium
Ornithogalum dubium, popularly known as the sun star or orange star plant, is a bulbous perennial native to South Africa prized for its clusters of vivid orange to yellow star-shaped flowers held above strap-like leaves. A favorite of florists and potted gift plants, it blooms from late winter through spring before entering a summer dormancy.
Chincherinchee
Ornithogalum thyrsoides
Chincherinchee (Ornithogalum thyrsoides) is an ornamental bulb native to South Africa, prized for its immaculate white or cream flowers arranged in dense pyramidal clusters. Highly valued as a cut flower for its exceptional longevity — blooms remain fresh for weeks after cutting. WARNING: all parts of the plant, especially the bulb, are toxic to humans and pets.
Star-of-Bethlehem
Ornithogalum umbellatum
Star-of-Bethlehem (Ornithogalum umbellatum) is a small bulbous perennial native to Europe, the Mediterranean, and southwestern Asia. It produces star-shaped white flowers with green stripes on the outer petals, blooming in spring in umbel-shaped clusters. The plant goes dormant in summer after flowering. WARNING: All parts, especially the bulbs, are highly toxic to humans, cats, and dogs due to cardiac glycosides.
Ivy Broomrape
Orobanche hederae
Ivy broomrape (Orobanche hederae) is a holoparasitic plant that lacks chlorophyll. It grows exclusively on the roots of ivies (Hedera spp.), from which it absorbs all its necessary water, nutrients, and carbohydrates. The stem ranges from yellowish to purple in color, reaching up to 60 cm in height, and the flowers are cream-colored with reddish-brown veins. The plant blooms from spring to summer and produces a vast number of tiny seeds. It is native to Central and Northern Europe as well as parts of Asia.
