The short answer to your question is: It is too early to tell.

The longer answer is: What you are asking about is the newest growth, a new pseudobulb. It is not mature enough to have opened its leaf. The sheath, if it produces one, will emerge from the place that the leaf joins the top of the pbulb. But, that will not happen until the growth has reached full height and the leaf has spread open.

I see, I thought the new growth was a sheath. This is torture! My mom brought this back from Florida for me this past winter and I didn't think I'd get it to bloom but I'm trying my hardest!

It will flower with the right treatment. Fertilize that new growth. That growth will produce any flowers you will get. Give it plenty of light and water when almost dry. Don't overwater!

It's most likely a winter bloomer, so keep up the care into the cool weather. Most winter bloomers like the temperature drop in Fall. Since you are in zone 7 you can probably leave it outside through Sept/Oct. Not sure where you live.

Jane, What makes you think it is a winter bloomer?

Based on color of leaves, I'd say it is getting plenty of light.

Patience grasshopper...

I personally find that "most" mature catts grown outdoors and indoors bloom multiple times a year. In my opinion it may have to do with the changing conditions when switched between those environments, but I know there are also catts that bloom intermittently naturally.

Good luck,

Bob

I think there is a species of a cattleya in bloom somewhere at any given time...

it is c. leudemanniana x sib from the botanical gardens in Sarasota for what it's worth... It was in bloom when it was given to me in March. The corner of the deck where it is lounging for the summer gets morning sun, shade from 12-3 when a part of the roof blocks the sun, and then the very corner of the deck where the cattleya, catasetum and dendrobium are gets some more afternoon sun. Unfortunately I can't find dappled sun on the property so this was the best I could come up with!

If it was in bloom when you got it, expect that it won't bloom again fro 6-9 months later. First the leaf will totally open and eventually you might have a sheath with a bud.

Harvey, because the leaf is just growing. Bulb needs to mature.

Jane, naturally it needs to mature. But from where it is now the p bulb could flower in a month or 2. But with the news it bloomed in March, it is possible that the next bloom will be in March. However Many orchids will bloom more than once a year. According to AOS this species in habitat blooms From December through March.

I have several cattleyas in bloom now in the summer heat.

You have a species orchid, one of my favorites!

Many hybrids bloom more than once a year, but now that we have its name, we can tell you it will be next winter. I would take it out of that deep pot. It needs good air circulation. If you want it resting in that pot, filll the bottom with rocks. You want air all around the plant. Your other orchids look good. If you rebloom them, this Catt should rebloom also. Your light sounds good. Give it regular feeding and you will be rewarded with blooms.

Harvey, I think I stated in my post that is 'most likely a winter bloomer.' You seem to disagree with that.

I have many, many Catts (too many!). I have Catts which bloom on and off all summer. I have others who bloom once a year like clockwork. Since this Catt is just starting this growth I would be amazed if it bloomed in a month or two.

Anything is possible of course. But I'd bet on it being a winter bloomer. BTW, I would consider March winter except the OP is in zone 7 which might cause it to bloom in November, December.

Just my opinion, not an argument Harvey.

Jane, your guess of winter came before the info of a march bloomer and before there was a name. So that was a lucky guess. Like I said above Cats will bloom all months of the year. And the timing from new growth to bloom is also varied. From a couple of months to several months or more. Saying a noid cat is most likely to bloom next winter due to new growth is nothing but a guess. In this case, after the facts, a good guess. Currently I have one of my favorite summer blooming orchids with new canes a little bigger than the one pictured here. I'm certain it will bloom in the next 30 to 45 days.

This cat is currently in bloom. When the bulbs grew to full size it immediately started filling the sheaths and then flower. There have been others that grow the bulb and sheath and sit there for months and finally bloom. My point is that there is no reliable timing sequence from bulb to flower.

You have the last word, Harvey.
