Key Ingredient In Love Potions

These orchids were grown in Thailand where there are many hybrid and wild orchid species. The larger orchid is called a Red Sonja, and the other hybrid is aptly named Candy Stripe. Israeli Ruscus, the greens accompanying your orchids, are grown in California and they will try very hard to outlast your orchids!

These orchids bloom in alternating sequences and under the proper conditions, they take quite a long time to wither. In fact, the last time we sent out similar hybrid orchids, we had several customers call to tell us that theirs had lasted more than 4 weeks! They must have had excellent care, and perhaps the location of the vase was just right to sustain them. For any cut flower to last four weeks is very unusual! On the other end of the spectrum, some wild orchid species bloom and wither all at once… needless to say we won't be sending you those!

The Greeks used Orchids as an aphrodisiac

I used to think that orchids were very fragile and all very similar, but no plant family is more diverse. Actually, the orchid family is the largest plant family we know about, and orchids can be grown in almost all possible environments! They actually grow wild on every continent except Antarctica. (No surprise to me… does anything grow there beside algae?)

Orchids have some unbelievably unique characteristics. The mere fact that their roots can live on air is enough to make us wonder how they can sustain themselves. Their roots are actually quite different from those of any other plants. A special sponge-like layer of tissue called "velamen" completely covers each root. This special sheathing acts as a moisture collecting device while protecting the roots from direct sunlight. Wild orchids often find bizarre places to grow. It's not uncommon to find them in the crevices of rocks on the side of a cliff!

About 25,000 orchid species have been identified!


This family is amazingly diverse… from the thimble-sized Mystacidium Caffrum to the 20-foot-tall Renanthera Storei. Some orchids produce blossoms no larger than a mosquito, while others are as large as a 12" dinner plate. And our Twenty First Century propagation methods and hybridizing trends are offering us more choices than ever before. The many species have different shapes, forms and growth habits. Some bare large flowers of bright hues, while others have little flowers of softer tones. They may flower singly or in small groups of two or three per stem. Some will bloom in a big cluster or a branch, yet others bend down in a flowing cluster. Their scents also run a wide gamut, ranging from those without any smell, to a soft and subtle scent, and to a more full-bodied and pungent fragrance. (No wonder people grow orchids for a hobby… they are so interesting.)

TEMPERATURE is the most critical factor in blooming

Orchids are native to the foothills of the Himalayas and are accustomed to cool conditions. Their tall spikes have from 10-25 flowers ranging from 2 ½" to 6" which last from one to three months when planted. Many are fragrant and their long leaves make them very distinctive and sophisticated indoor plants.

These orchids grow at fairly high altitudes in many areas of the world… China, India,Thailand, Burma, Taiwan, and parts of Australia. We need to emulate their natural habitat if we are to grow these orchids successfully at home. They are among the easier orchids for beginners and their spectacular long lasting flowers make the effort really worthwhile.

We can trace orchids back to the Early Greeks who regarded their delicately constructed blossoms as an icon representing beauty and love.

How To Grow Orchids

WHERE - Orchids are best kept outdoors from May to September, but bring them in before the danger of frost. Shelter them from hot sun and from the rain as well, since you need to control the watering. During the winter, a cool room is the best spot for your orchids. If the room is too warm, the flower buds may drop off and you will have to wait another year to see the effort of your labor!

HUMIDITY - All orchids need humidity so put your pots on a stand or tray so they won't have wet feet, and then put the stand and pot in a larger container with pebbles and water. In the hot summer weather it's a good idea to mist your plants every day, but not in the winter.

TEMPERATURE - In summer the plants will tolerate temperatures up to about 85'F (30'C) and in winter they are happiest with a night temperature of 5O'F(IO'C).

WATER - The plants require quite a lot of water in summer, roughly about a pint a week and in exceptionally hot weather even two pints twice a week (providing the plants are in open bark which will drain immediately). In winter they need much less - about a half a pint every week to 10 days. The large amount of water is necessary in the summer to maintain very large pseudobulbs and to help with new growth.

FEEDING - These plants are quite hungry for orchids and need to be fed all the year round. They should be fed every week to ten days. On the fourth week hold the food and give them plain water to avoid any build up of undesirable chemicals around the roots.

The plants seem to thrive on foliar feeding, and if you are using this method both sides of all leaves need to be sprayed. Any suitable half strength feed will do, or special orchid food from nurseries and garden centers. Your orchids will benefit more by giving them a higher nitrogen feed early in Spring to help with the growth of new pseudobulbs. By giving a food such as Tomarite or Phostrogen from late June or beginning of July, you will help to ensure that flower spikes are formed. These usually peep through sometime in August or September.

Standard orchids can become very large and take up lots of room, but they are very beautiful and their flowers last for many weeks even when cut. The plants are well worth a little tender loving care. If you have tight quarters, miniature orchids are now available, and both kinds of plants can be divided to provide new plants.

POTTING is usually done in the spring after blooming, usually every two years or when the potting medium decomposes. Shake all the old potting mix off the roots, dividing the plant if desired. Divisions of green bulbs with leaves must have 3 to 4 bulbs minimum to bloom. Bulbs without leaves are called backbulbs, and need special care to grow.

Pick a potting mix that will hold moisture well… a medium-grade fir bark with peat moss and perlite is a common mix. Select a pot that will allow for at least 2 to 3 years of pseudobulb growth before crowding the pot. Placi the active growing bulb(s) of the division farthest from the side of the pot. Spread the roots over a cone of the mix in the bottom of the pot, and fill the pot with medium, working it among the roots, tamping firmly. The junction of roots and pseudobulbs should be about 1/2" to 1" below the top of the mix. Keep shaded, drier at roots but humid, until new roots grow.

Note: Backbulbs may be left on the division to add strength, or removed to propagate. Take single backbulbs, and bury halfway in a bark or peat/sand mix. Keep shaded and warm until new growth sprouts, and pot as above. It may take up to three years to produce a blooming-size plant from this method.

Qrchid Q & A

Where can I get more information?
There are many excellent books available to help a novice grower learn more. The American Orchid Society (AOS) offers an extensive book list, all of which can be ordered online at their Bookshop. Among the many publications in this listing is a variety of illustrated handbooks published by the AOS covering many topics, including the control of common orchid pests and diseases, orchid photography, and procedures for judging and exhibition. The AOS also offers a series of cultural video tapes, all providing the most updated information. Perhaps the most useful learning step is to become a member of your local orchid society. Currently, there are more than 550 Affiliated Societies scattered around the globe.

What sort of soil do orchids need?

Would you believe that most don't require any soil! Orchids can be divided into four types according to growing conditions. Most are classified as "epiphytes," or air plants, which grow chiefly on trees. "Lithophytes" cling to the surfaces of rocks. "Saprophytes" grow in decaying vegetation on the forest floor, and terrestrials anchor themselves in soil or sand. Since most orchids are epiphytes, they can be grown on tree bark (fir or redwood), crumbled charcoal, pebbles, or on tree-fern or cork plaques.

Are orchids hard to grow?

No more difficult than many popular flowering plants… if you grow other ornamental plants either in the garden or indoors, you can grow orchids. Once a hobby for the wealthy, orchids are now reasonably priced because of modern reproductive methods. A little word for the wise… the hardest thing about orchids is to not become addicted. Trying to own one orchid is like trying to eat one peanut!

Should orchids be protected from drafts?

No. As a matter of fact, orchids require moving air. They do best where there is a steady, moist breeze. However, if grown indoors, blooming plants should be positioned away from air-conditioning or hot-air vents.

Are most orchids fragrant?

Some are so powerfully scented they will perfume an entire greenhouse or living room. A few orchid fragrances defy description, while others mimic familiar aromas… raspberry, coconut, lilacs and citrus. Others have no scent, but rely on shape and color to attract insects or birds for pollination, thereby continuing the life cycle of the species.

Are orchids short-lived?

Most are long-lived. In fact, some species are virtually immortal, given the proper attention. Divisions or propagations of orchids discovered in the 19th century are still growing and flowering today.

How often do orchids bloom and how long do orchid blooms last?

Some bloom once a year, others bloom several times a year, and some even bloom continuously. Blooms of hybrids of the genus "Cattleya" may last from one to four weeks on the plant. Those of the genus "Phalaenopsis" commonly last from one to four months.

Is conservation of orchids an important issue?

Absolutely! Sadly, orchid species are becoming extinct faster than they can be described and classified. Threats to orchids originate primarily from loss of habitat and collecting. The American Orchid Society (AOS) advocates the purchase of only artifically propagated orchids, either from meristems or seeds, which will help discourage the collecting of orchid species at home and abroad. The AOS also encourages orchidists to pollinate orchid species already in their collections and to share the seedlings with their fellow orchidists.
