Many neotropical orchids are pollinated by male orchid bees, which visit the flowers to gather volatile chemicals they require to synthesize pheromonal attractants. Males of such species as Euglossa imperialis or Eulaema meriana have been observed to leave their territories periodically to forage for aromatic compounds, such as cineole, to synthesize pheromone for attracting and mating with females. Each type of orchid places the pollinia on a different body part of a different species of bee, so as to enforce proper cross-pollination.
This is not a type of orchid you’ll want to place on your windowsill, because the stems grow up to four feet high. Phaius orchids have large, strappy leaves, and they usually produce petals that are yellow, purple, or white. Also known as the Nun’s Cap orchid, it is a winter bloomer and makes a great addition to anyone’s garden, regardless of what else is planted there.
In the wild, Phalaenopsis are epiphytes and grow on trees in a constantly moist environment. They usually have long flower spikes and therefore look very graceful. These types of flowers have the power to add elegance to the home and brighten up a dull atmosphere, even if your boyfriend leaves his socks on the floor. Phalaenopsis are now widely grown as houseplants. Even though they usually bloom only once or twice a year, their flowers can often last for two to three months.

The petals of these orchids are a bit smaller than those of other orchids, and it consists of many spikes so there are a lot of those petals to look at. The Cymbidium orchid has won several international flower awards, and it comes in colors such as yellow and red (the Showoff), lime green (the Chica), and bright pink (the Frae). These and other Cymbidiums are excellent for first-time growers, because they are easy to grow and are low-maintenance. They also do better in cold climates than many other orchids do, and they make beautiful centerpieces.
The Coelogyne orchid genus gets a lot less attention than it deserves. The plants have beautiful, fragrant flowers, can tolerate drought and neglect, and rapidly develop into massive, impressive specimens. The best-known species come from the foothills of the Himalayas, where the elevation produces cool temperatures. The largest-flowered species in the genus, Coelogyne cristata, is one of these cool-growing types.
The sizes of the plant and its pot are also major factors to take into account in determining watering frequency. A smaller pot holding less potting mixture dries out more quickly than a larger pot holding more potting mixture. Meanwhile, a smaller plant takes up water less rapidly than a larger plant. Careful observation is, once again, the best way to know how to water your phalaenopsis orchid.
Always water early in the day so that your orchids dry out by nighttime. The proper frequency of watering will depend on the climatic conditions where you live. In general, water once a week during the winter and twice a week when the weather turns warm and dry. The size of your orchid container also helps determine how often you need to water, regardless of climate conditions. Typically, a 6-inch pot needs water every 7 days and a 4-inch pot needs water every 5 to 6 days.
The family encompasses about 6–11% of all seed plants. The largest genera are Bulbophyllum (2,000 species), Epidendrum (1,500 species), Dendrobium (1,400 species) and Pleurothallis (1,000 species). It also includes Vanilla–the genus of the vanilla plant, the type genus Orchis, and many commonly cultivated plants such as Phalaenopsis and Cattleya. Moreover, since the introduction of tropical species into cultivation in the 19th century, horticulturists have produced more than 100,000 hybrids and cultivars.

A very showy flower, this type of orchid comes in colors that include white, yellow, brown, purple, red, and a few varieties that are multicolored. They can be a challenge to grow, but they grow well if the temperature is below 80 degrees Fahrenheit because they are used to cool or cold climates. The Odontoglossum orchid has stems that can grow up to four feet high and blossoms that can reach up to six inches in width. Between 20 to 150 blossoms grow on each stem, and their petals are ruffled and very fragrant.
Speaking of cut Cymbidium flowers, my friend has several outdoor Cymbidium and the once-a-year flowering always brought her lots of joy and pride. It’s like an annual EXPLOSION of flowers that fills her whole back yard! Right before the prom, their teenage neighbor forgot to get his date some flowers, and for some reason, he thought it was okay to make a bouquet out of these Cymbidium flowers without any permission. She was so upset about the loss that the thoughtless boy had to make up the mistake by working in her garden for the rest of the year. The moral of the story? If you decide to steal someone’s orchids, you’d better not get caught! Learn more about Cymbidium orchids.
Orchid roots are surrounded by a tissue-paper thin membrane called velamen. This multi-purpose membrane soaks up large amounts of water quickly, adheres to rough surfaces, and promotes the exchange of minerals and salts. Like an expensive water meter, orchid velamen is an excellent indicator of your plant's water needs. Dry velamen is white or silvery, and freshly watered velamen is green or mottled (depending on the species).
Epiphytic orchids, those that grow upon a support, have modified aerial roots that can sometimes be a few meters long. In the older parts of the roots, a modified spongy epidermis, called a velamen, has the function of absorbing humidity. It is made of dead cells and can have a silvery-grey, white or brown appearance. In some orchids, the velamen includes spongy and fibrous bodies near the passage cells, called tilosomes.
I wish I could tell you exactly how often to water your phalaenopsis orchids and how much water to give them and be done with this post. Unfortunately, there is no one size fits all answer. When it comes to watering any plants there are lots of factors to consider that’ll make the amounts and regularity vary. I’ll go over all those factors so you can see what will be the best for your own situation.
The seeds are generally almost microscopic and very numerous, in some species over a million per capsule. After ripening, they blow off like dust particles or spores. They lack endosperm and must enter symbiotic relationships with various mycorrhizal basidiomyceteous fungi that provide them the necessary nutrients to germinate, so all orchid species are mycoheterotrophic during germination and reliant upon fungi to complete their lifecycles.
This type of orchid has over 200 species and has a star-shaped appearance. Most of them have small- to medium-sized blooms and come in colors such as yellow, white, or light green, although most of them are white. The flower has a wonderful fragrance, needs even amounts of water, and prefers temperatures between 60 and 80 degrees Fahrenheit, mainly because they are not a bulb plant and therefore cannot store water. They also look beautiful in hanging baskets and pots.
The structure of the leaves corresponds to the specific habitat of the plant. Species that typically bask in sunlight, or grow on sites which can be occasionally very dry, have thick, leathery leaves and the laminae are covered by a waxy cuticle to retain their necessary water supply. Shade-loving species, on the other hand, have long, thin leaves.
The quality of water used, whether for spraying or watering, is of great importance. Since tap water has often been chemically treated, generally with chlorine, it should be used with caution. The best water for orchids is undoubtedly rainwater. Rainwater, as it passes through the air, dissolves and absorbs many substances such as dust, pollen and other organic matter. This enriched rainwater contributes to the nourishment of the plant.
