Paphiopedium orchid at Pennyslvania’s Longwood Gardens
Years ago I was touring the Filoli mansion in Woodside, California when I came across an unusual flowering plant. It perched high on a table in an upstairs hallway and sported tiny, reddish-brown blossoms. Plunging my nose into the petals, I discovered it smelled exactly like chocolate.
Our guide explained that the plant was ‘Sharry Baby,’ or Chocolate Oncidium; an orchid admired for its lovely shape and abundant flowers. This was news to me, because like many people, I knew mainly only one variety and that was called Phalaenopsis.

I’ll admit I was naive. There’s a lot more to the species than the common moth orchid. And thus I began my immersion into the world of these beautiful tropical plants, a journey that continues today.
Who knew orchids grew on trees?
Branching out, I began searching for opportunities to grow my knowledge. So a year later I found myself touring an orchid garden called Lo de Perla located high on a mountainside in Mexico. There, deep in the jungle, thousands of orchids known as epiphytes grew wild on tropical trees.
Indeed, I learned that most orchids are epiphytes, meaning they grow on top of other plants. Moreover, Lo de Perla had a seemingly endless number of varieties. Additionally, the garden had a small greenhouse that housed other rare and unusual species. It was a great way to study the flowers.

The U.S. Botanic Garden Annual Orchid Show
Then last year, I heard about a show being held at Washington, DC’s Hirshhorn Museum. Located in the building’s main lobby, the annual exhibition is curated jointly by the U.S. Botanic Garden and Smithsonian Gardens. The display, which was created by the museum’s own designers, featured hundreds of orchids in a customized gallery. Each species was presented in its own cubby hole in a single white pot.

However last February, I received my best education yet at Longwood Gardens, where each year in late winter the property hosts an orchid exhibition. Not only was the show instructional, but it was also astonishing. The place was brimming with jaw-dropping installations.

In particular, I noticed the many moth orchids hanging above us throughout the conservatory.
Ample signage displayed throughout the garden confirmed that the orchid family is a big one. One of the largest families of flowering plants, it is considered the most evolutionary advanced plant family in the world, due to its highly specialized floral structure.
Learning from the collection at Longwood Gardens
Longwood is known for showcasing unusual species. Consequently, I was delighted to discover an exhibition of rare Phalaenopsis hybrids from Taiwan along a passageway. They demonstrated a specialized technique perfected by experts in that country for growing these flowers. The plants, which featured strands of flower-pairs blooming in unison on single stalks, are notable for the length of time they hold their blossoms.

However the real education began when, winding my way through a maze of greenhouses, I spotted an area devoted entirely to instruction. To the left of the staff potting room, I found hundreds of varieties from Longwood’s own collection.
Here at last was orchids for beginners! Furthermore, attached to the wall were signs describing the main characteristics of each species. So if you, like me, are looking to learn, then see below.
The main orchid varieties
Cattleya orchids, also known as corsage orchids, are exceptionally showy and often fragrant. They were the most popular variety in the early 20th century.
Miltoniopsis orchids, commonly known as pansy orchids, are native to Central and South America. They are most notable for their large flowers and long stems that can carry up to seven or more blooms at a time.
Vanda orchids are native to tropical and subtropical Asia and Australia. They are known to be some of the bluest flowers in the orchid world (although they looked purple to me.) Aside from blue, they range in color from dark purple to red, pink, yellow and white.
Unlike many varieties, cymbidium orchids need cool temperatures and bright light to flower. Most carry many flowers on a single stem. They are often used in cut flower arrangements.
Dendrobium orchids are native to tropical and subtropical Asia and Oceana. They are unusual in that they grow on rocks in addition to trees. A large genus with over 1,000 species, they are sometimes referred to as ‘rock orchids.’
Masdevallia orchids can bloom year round in the right conditions. Native to Mexico and Central and South America, they are sometimes referred to as ‘little flag orchids.’
Paphiopedium orchids, also known as slipper orchids, have a large pouch that resembles a shoe. Native to China and tropical Asia, they usually carry just one flower per stem.
Oncidium orchids (of which the aforementioned chocolate-scented Sharry Baby is one) are a large genus of over 300 species. Commonly known as Dancing Ladies, they are native to South America.
Finally, the most common variety Phalaenopsis are the easiest to grow. Moth orchids have large, flat blooms and thick green upright leaves. Native to tropical and subtropical Asia and Australia, they grow mainly as epiphytes.
Planning to head to the store? Many orchids are easier to care for than you might think. Just remember, since most of them are used to growing in air, they don’t like lots of water or heavy soil around their roots.
Water once a week in the morning, allowing the plant to completely dry out between waterings. Most importantly, never leave your orchid standing in water, which will quickly rot the roots.
