The regal Cattleya, also known as the "Corsage Orchid" was extremely popular as a cut
flower in the United States
in the 1950's and yet its history dates back to the early 1800's when William Cattley first bloomed this orchid
cultivation. Large fragrant blooms are the signature of this classic orchid. The color "orchid" comes from the
color of many Cattleya although the genus actually includes a wide variety of colors. The genus Cattleya is
native to Central and South America.
The culture of the Cattleya orchid involves bright light while the pseudobulb is maturing. Their light demands
can prohibit successful blooming in a home unless supplemental lighting or summers outdoors are provided. The
term "Cattleya culture" is often applied to a group of related genera that have the same basic culture needs as
Cattleya and are often crossed with Cattleya to create delightful hybrids. These related genera include
Potinara, Laelia and Brassavola.
The Cattleya is a sympodial orchid which means that
it grows pseudobulbs along a central horizontal rhizome. Each year a Cattleya orchid will grow one or more new
pseudobulbs from which the bloom for that season will come. A Cattleya will not bloom on old pseudobulbs yet
those pseudobulbs will provide strength for the plant. In the seasonal bloom cycle of a Cattleya we are looking
for the emergence and growth of new pseudobulbs, bloom sheaths to appear from the top of the pseudobulb, and
blooms to appear from the sheath. This cycle is illustrated below.
The Cattleya is often in bloom for Mother's Day in the spring but many bloom in the fall as well. As the
pseudobulbs on our Cattleya mature we begin to look
for the bloom sheath that emerges from where the leaf meets the top of the pseudobulb. The sheath will cover the
developing bloom as it matures. Eventually the bloom spikes push their way through the
covering sheath and develop into flowers. In some cases a sheath may form without buds or the buds may appear
much later. Usually the developing buds can be seen, or at least felt, through the sheath.
As the pseudobulb matures the outer paper-thin layer turns brown and/or white and may begin to peel. This layer
is called a 'sarong' and it is perfectly fine to let it be or to peel it off as you prefer.
Peeling off the sarong eliminates one place where bugs may try to hide.
In some cases it can be beneficial to open the top of the sheath so that the developing bloom does not rot from
excessive moisture within the sheath.
When the time is right the developing buds will push their way up through the sheath extending upward into a
cluster of fragrant blooms.
Once the bloom is gone and the flowers have fallen off the sheath will begin to yellow. At this point we can cut
the sheath and bloom spike off just above the leaf.
The pseudobulb will continue to provide sustenance to the plant for at least a few seasons, even after it becomes
leafless. Think of these old pseudobulbs as energy storage tanks for the plant.
Once a pseudobulb has shrunk and become brown, it should be removed at the next repotting by cutting it off at
Next we will be looking for the next pseudobulb to begin to grow at the base of those that just bloomed as the
growth cycle starts once again.

“This fall I religiously followed your advice, creating an environment of shortened
days and lower temps in order to encourage blooming...I was successful. FINALLY!! Thank you, thank you!!
Both of my plants decided to bloom and they look beautiful. I wanted to share the good news and
my gratitude with you. Thanks again!”Laurie J.
“The potting medium you sent is gorgeous!! It's superior to the bark I've been
buying at Lowe's. I can't imagine what (my orchids) will do when I put them in your potting mix. It even
smells fresh!! Many, many thanks. I'll be ordering from you again.”
“Folks, My order [slotted pots and mix] arrived way before expected - and I am extremely happy with it! I harvested "babies" off my African violets to give as Christmas gifts this year - and they have tripled in size in the great potting soil and look so good - I can't wait to "gift" them!”Susan S.
“From beginning to end, rePotme has created a customer EXPERIENCE that is superior and delightful. The informative website contained many articles and videos that were extremely helpful to me as an orchid novice. There, I was guided to a potting mix (one of many!) that I wanted to try out. The checkout process was a breeze, and I especially enjoyed the fact that I could sign on with my Amazon account and did not have to create a brand new account”
“I have received my new Carousel Orchid Pot and Saucer in Orange Amber. I love it!! I would like to let you know that before I opened the wrapping to each piece (wrapped separately for those who may read this), rePotme won me over. Not only did I receive it within the expected time frame, your method and precise detail to packing it impressed me the most. It may not seem important to some, but I really appreciated it”
“My order arrived today and not only am I impressed with the speed of delivery, and how carefully it was all packed, but the quality of everything really surpassed my expectations. Between the supplies I ordered and your fantastic website with instructional texts, photos and videos, I feel very confident to move up to the next level of orchid growing”
