Orchids are primarily found in tropical and subtropical regions, with the largest concentration of species in Asia, the Americas, Africa, and the Pacific Islands. They prefer warm, humid climates, although some species can tolerate cooler temperatures. Orchids can be categorized into ephemeral orchids, which bloom for one day, and field orchids, which bloom for 2 to 7 days. North America has about 250 native orchid species, but approximately half are endangered or threatened due to habitat destruction and poaching.
Orchids thrive best in fast-draining growing mediums, and they can be found in every US state and much of Canada. To find native orchids in your region, contact your local native plant society or botanic garden. A step-by-step guide to mastering orchid care can help you learn about different types of orchids and their basic care.
Orchids are epiphytes that grow on trees, but some are terrestrial in the ground, while others are lithophytic and grow on rocks. They thrive outdoors, especially when it rains, but make sure they are shaded. Wild orchids can be found in various nature reserves, roadsides, dunes, or along ditches. Orchids also grow in “low rent” real estate, such as tree trunks, rocks, and cliffsides, due to their evolved behavior in tropical climates.
Orchids have diversified to grow in a wide variety of habitats, from arctic tundra to tropical rainforests, swamps to mountaintops, and more. Hardy orchids can be grown outdoors in various locations, such as raised beds, large pots, flower borders, rockeries, and in the shade of trees or shrubs.
A new extensive study of genetic relationships among orchids has clarified the relationships among orchid groups and their distribution. Orchids are found on all continents except Antarctica, but the vast majority, such as Dendrobium delacourii, are native to the tropics.

Do orchids grow anywhere?
The genus Orchidaceae is distributed across the globe, with species native to over 200 countries and territories, with the exception of Antarctica. To gain an understanding of the diversity of species in each country or region, one must undertake a comprehensive examination of the globe.
Do orchids grow in a field?
Orchids are epiphytes that grow on trees, with some terrestrial in the ground and others lithophytic on rocks. Most species are found in tropical to sub-tropical regions, with trees with rough bark and crevasses being favorite sites. Epiphytic orchids develop a pseudobulb that stores moisture and have thick leathery leaves with a protective cuticle. Terrestrial plants root in rich humus and have fleshy roots, while lithophytic varieties nest in organic material deposited on rocks.
Orchids’ natural habitat extends to all parts of the globe, except Antarctica, where it is too cold to support their growth. Every other continent hosts species of orchid, and they are known to migrate from their specific range.
North America boasts over 200 native species of orchid. The most cold-hardy orchids come from the cymbidium and dendrobium groups and can even survive brief freezes. One of the most commonly known and used orchids is the vanilla orchid, which hails from South and Central America and is considered semi-epiphytic. After flowering and proper pollination, the plants produce beans, which are the source of the sought-after flavor.
Where do orchids naturally grow?
Orchids are highly adaptable and can grow in almost all climates except for extremes. They are found in both pantropical and endemic habitats, with most species growing in tropical forests. Neotropical orchids are found in southern Central America, northwest South America, and countries along the Andes Mountains. However, most orchids depend on a single pollinating species, and if that species is eliminated, the orchid that depends on that species becomes threatened by extinction. This could lead to habitat fragmentation and rainforest destruction, potentially causing the extinction of many orchid species.
Can orchids grow in sandy soil?
Habitat Bog Orchids are hardy orchids native to eastern North America, primarily found in bogs, pocosins, and fens. They thrive in open, sunny wetland habitats with consistently damp peat/sand soil. These species can grow across multiple hardiness zones from Zones 3 to 9, making them adaptable to deep winter freezes to milder temperate winters. They often grow in association with sphagnum moss and carnivorous plants, making them excellent companions for bog gardens.
To grow Bog Orchids, use a standard CP soil mix of peat and sand, with chopped sphagnum and pine bark fines added for better growth. Mature bog orchids prefer a wider large pot, as their roots usually grow long and shallow. They thrive in evenly moist soil but not soaking wet.
During winter dormancy, allow the soil to become drier but remain somewhat moist. Water from below with mineral-free water or use the tray method. Provide full sun, and provide a winter mulch of 4-6″ of weed-free hay or pine needles.
Bog orchids can be propagated from mature rhizome divisions, and seeds do not need mycorrhizal associations. They can be propagated from mature rhizome divisions, and some require stratification for cool, damp winters. Fertilization is not necessary for Bog Orchids, but they can benefit from low doses.
Bog Orchids are best grown outdoors and should be repotted every few years in a fresh CP soil mix. Plant in the center of the pot with the crown about 1/2″ below the surface, and divide any multi-bud plants before active growth begins. A soil top dressing of living Sphagnum Moss works well, but repotting or transplanting may set flowering back by one year.
Can orchids be grown in the ground?
To grow orchids outside, you need to determine the orchids that thrive in your region and climate, regulate shade and water, and choose a suitable location. Common methods include pots, ground, raised beds, or trees. Find a variety of orchids suitable for your area by visiting local garden stores or searching for “orchids native to your area”. Cymbidiums are suitable for cooler summer nights, while vandas or cattleyas are suitable for consistently hot summer nights.
Do orchids naturally hang?
The orchid family, which includes over 880 genera and 22, 000 species, is the largest and most diverse flowering plant family. Most orchids are tropical plants, living as epiphytes or “air plants” hanging on to trees for support. Some are lithophytes or “rock plants” growing on or among rocks, while the remaining orchids are terrestrials growing in the loamy detritus of the jungle floor.
To give general guidelines on orchid care, there are only several dozen species widely produced and even fewer available at local nursery. Hybrids, created by crossing different species and genera, are often sold at nurseries, florists, hardware chain stores, and groceries. These hybrids are rewarding house plants to grow and are relatively easy to care for if taken a little time to understand their basic needs.
Orchid growth environments are crucial for understanding orchid care. In a jungle, an orchid clings to a tree, absorbing water from the humid air and using organic matter decaying in branches or animal droppings. In a typical home environment, the orchid has thick stems called “pseudobulbs” to store and hold water for dry periods. Understanding the natural conditions in which the orchid grows is critical to understanding what the orchid needs for its care. Orchid Starter Kits offer essentials for growing a happy, healthy orchid.
What is the natural environment of orchids?
Orchids are epiphytes that grow on tree trunks or branches, deriving support from the tree but not food from it. To flourish, orchids require a constant warm temperature, humid air, and ample water to facilitate the growth of roots in the hollows of tree branches and bark. The growth of orchids is slow and they are unable to withstand periods of drought or fluctuations in temperature.
Do orchids grow underground?
Underground orchids, which live in soil as small white rhizomes, are vulnerable to pollination by tiny fly larvae. The pollinator mistakenly lays eggs in the orchid, causing it to become a fungus. All Rhizanthella species are currently listed as critically endangered, with R. gardneri and R. johnstonii being critically endangered. R. slateri and R. omissa are also endangered. The most recently discovered species, R. omissa, has not yet been listed, but its scarcity makes it highly vulnerable.
What is the best environment for orchids?
Orchids require bright, indirect light, often from east or west-facing windowsills. They thrive in humid, tropical environments, so avoid direct sunlight. To maintain a humid atmosphere, mist foliage with tepid water or place the pot on a tray of damp gravel. Different types of orchids require different care, so keep the plant label after purchase. Grow orchids in specialist compost, avoid excessive watering, and feed with orchid fertilizer from spring to autumn. Follow essential orchid care tips to ensure long-lasting flowering and growth.
Do orchids exist in nature?
Orchids are a diverse group of flowering plants found in almost every habitat on Earth, except glaciers. They are one of the two largest flowering plant families, with about 28, 000 accepted species distributed across 763 genera. The Orchidaceae family encompasses 6-11 of all seed plant species, with the largest genera being Bulbophyllum, Epidendrum, Dendrobium, and Pleurothallis. It also includes Vanilla, the type genus Orchis, and commonly cultivated plants like Phalaenopsis and Cattleya.
Since the introduction of tropical species into cultivation in the 19th century, horticulturists have produced over 100, 000 hybrids and cultivars. The world’s richest diversity of orchid genera and species is found in the tropics.
Can you grow orchids in dirt?
Tropical orchids, like paphiopedilums and cymbidiums, grow in soil, while most tropical orchids are epiphytes, growing in the air. Their fleshy roots are covered with a layer of white cells called velamen, which absorbs water and protects the roots from heat and moisture loss. An orchid growing medium must provide good air circulation, allow quick water drainage, and provide a secure clinging to the roots. Orchids can grow in various materials, such as peat moss, fir bark, dried fern roots, rock wool, perlite, cork nuggets, stones, coconut fiber, lava rock, or a blend of these materials.
Fir bark nuggets are the most popular growing medium. Humidity is crucial for tropical orchids, with most preferring 60 to 80 percent. Growers often use a humidifier or set their orchids on rubber grids in waterproof trays or gravel-filled trays. Some orchids also benefit from being misted.
