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.
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.

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.
Oregano
Origanum
Origanum is a genus of aromatic Mediterranean herbs in the Lamiaceae family, widely known for culinary and medicinal use.

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.
Green Dunce Cap
Orostachys malacophylla
Orostachys malacophylla is a hardy, monocarpic succulent from the Crassulaceae family (the same family as stonecrops and sedums). The plant forms dense rosettes of fleshy, bluish-green to green leaves with a diameter of 4-15 cm and spreads via runners (stolons), forming dense mats of rosettes. In the autumn, mature rosettes produce a conical inflorescence up to approximately 20 cm with white to greenish flowers and yellow stamens—after which the specific flowering rosette dies, while the numerous offsets ensure the colony lives on. The species is very hardy (USDA zones 3a-8b) and tolerates heavy frost, and the plant is not considered toxic to humans or pets.
Rice
Oryza sativa
Rice (Oryza sativa) is an annual grass in the Poaceae family, native to Asia, where it has been cultivated for thousands of years as the dietary staple for more than half of the world's population. The plant forms clumps of slender stalks and long, narrow leaves, producing panicles with hundreds of small flowers that give rise to the grains. It is traditionally grown in flooded fields (paddies), where the water level controls weeds and maintains the constant moisture required by the species.
Deltoid Pumpkin
Oscularia deltoides
Oscularia deltoides is a succulent groundcover from the Aizoaceae family, native to the rocky and arid areas of the Western Cape in South Africa. It forms creeping cushions of triangular (deltoid) blue-green leaves, often with pinkish tints, edged with tiny translucent teeth that give it a frost-covered appearance. In spring and summer, it produces an abundant bloom of daisy-like flowers in magenta-pink or lavender hues, which are lightly scented and open during the day. Due to its extreme drought tolerance and ease of cultivation, it is highly valued as a groundcover, in rock gardens, and in containers.
Sweet Olive
Osmanthus fragrans

Renowned for its intensely fragrant, tiny white or yellow flowers, it is one of the most celebrated ornamental plants in Chinese culture. The flowers are used to scent teas, wines, and perfumes, and the plant holds deep cultural significance in China, where it is associated with the Mid-Autumn Festival.
Goshiki False Holly
Osmanthus heterophyllus 'Goshiki'
Osmanthus heterophyllus 'Goshiki' is an evergreen shrub in the Oleaceae family, native to Japan and Taiwan. The cultivar 'Goshiki' (literally meaning "five colors" in Japanese) is distinguished by its variegated foliage: the leathery, spiny leaves, similar to those of holly, emerge in shades of bronze-pink before maturing into green mottled with cream, yellow, and pink. In autumn, it produces small white flowers that are discreet but highly fragrant, often hidden among the leaves. Slow-growing with a compact habit, it is prized as a specimen plant, in informal hedges, or in mixed borders.
African Daisy
Osteospermum
Osteospermum, commonly called African daisy or Cape daisy, is a genus of roughly 70 species of daisy-like flowering plants native to South Africa and the surrounding region, belonging to the sunflower family (Asteraceae). Grown as mounding, spreading subshrubs or herbaceous perennials, they produce abundant 5 cm blooms in white, yellow, orange, red, coral, pink and purple, often with a striking dark or iridescent-blue center disc. In warm climates (USDA zones 9-11) they behave as tender perennials that flower nearly year-round; in cooler regions they are grown as fast-growing annuals or overwintered indoors. Prized for heat and drought tolerance once established, African daisies are popular as border edging, container spillers and ground cover in sunny, well-drained garden beds.
Bietou
Osteospermum moniliferum
Bietou (Osteospermum moniliferum) is a fast-growing, evergreen shrub in the Asteraceae family, native to the coastal regions of southern Africa—from the Cape Peninsula through KwaZulu-Natal to Mozambique and Zimbabwe. The plant grows up to 2 meters tall and equally wide, forming a compact, rounded growth habit with dark green, slightly serrated leaves. The characteristic yellow flower heads, with a diameter of up to 40 mm, bloom primarily in late autumn and winter, and are highly attractive to bees and other pollinators. After flowering, berry-like fruits develop that ripen into dark brown or black spheres, which are a favorite for birds. The plant is extremely drought-tolerant due to its semi-succulent nature and thrives in well-drained, sandy soil in full sun. It is easy to grow, grows rapidly, and has a lifespan of 8–12 years.
European hop-hornbeam
Ostrya carpinifolia
The European hop-hornbeam (Ostrya carpinifolia) is a deciduous tree of the Betulaceae family, widespread in the hilly and sub-mountainous areas of Southern Europe, the Balkans, and Southwestern Asia. It grows wild from sea level up to about 1300 m, often on calcareous soils and arid slopes, where it acts as a pioneer species capable of colonizing poor and degraded soils. It typically reaches 15-20 meters in height, with an oval crown, reddish-brown bark that flakes into thin plates, ovate serrated leaves similar to those of the common hornbeam but with more pronounced veins, and fruits enclosed in membranous bracts gathered in infructescences resembling hop cones, from which its English name "hop-hornbeam" is derived.
Ruby Necklace
Othonna capensis
Othonna capensis, popularly known as Ruby Necklace, is a creeping and trailing succulent native to the arid regions of the Eastern Cape, South Africa. Its cylindrical, finger-shaped leaves are grayish-green and develop intense ruby tones at the tips when exposed to plenty of sun and little water.
