My experience is that Catt crosses have invariable results. If they take and hold the seed pod, they may not produce viable seed. I have a failure rate of about 30% that wont germinate, even though the seed looks viable under a microscope. If they are to germinate, the first signs are normally evident at about the 1 month mark. - 3 months in and I am fairly confident that it wont happen.

Green pod culture also has a chance of lowered germination rates but it's preferred by some over dry see because of lower chance of contamination.

Would you give NOID phal seeds the same deadline for germination? I've been flasking some NOID catt seeds and phal seeds and the catts have germinated in all flasks (not great germination, but that's okay...then the population is better since I sprinkled too many seeds), but there's no sign of protocorms developing in the phal flasks and they're now...getting close to three months old. I've been considering tossing them, but I've been delaying it, thinking that maybe they're slower than the catts.

I find Phals germinate in the first week or two. They are fast to see results. 3 Months on and my guess is that they wont germinate, unless they are a slow growing species.

Seedling photos . . . finally.

Well, I finally got around to posting photos of my tiny seedlings:


img_0467-seedlings-504x470.jpg img_0470-seedlings-close-640x480.jpg



After a long process of rescuing protocorms from the original flasks, experimenting with growing those rootless protocorms on various media (live sheet moss, chopped fir bark, naturally-decomposed pine, pure perlite, and sphagnum), I found that the tiny seedlings seem to do best initially on moist, not soggy, sphagnum. When they started getting roots, I increased the moisture a bit and added weak fertilizer. I have maybe a dozen or two seedlings left, what you see is the best compot of the three I have left. These 4 little seedlings have the best leaves & roots.

Plucker, I suspect you are right. Although Rockbridge Lab will keep the flask up to a year, I don't hold much hope of having seeds from my most recent pod germinate.

Thanks for posting photos of the seedlings Catt. Wow, it is like a prem baby nursery, though - the one with the tiniest babies. You have a lot of loving caring ahead of you to raise these 4! I hope they all thrive.

LOL, well, you should have seen them before they grew ROOTS!! Really tiny back then. Yes, these are tiny, but they are positively huge compared to what I started with. It gives you an appreciation for how long it takes a wild plant to develop from seed - it is amazing that any develop at all! Though I am certain commercial producers of orchid from seed to a better/faster job than me, I still have an appreciation for how difficult and time-consuming this process can be.

Thanks for the update. Just reading about the process helps us appreciate the time and effort put toward the plants we have in our collections. I'm keeping my fingers crossed that you'll see these plants bloom some day.

Quick update on the seedlings. They are still growing slowly, a couple of the largest ones may be sending out a small lead (?). Or maybe my eyes are deceiving me. In any case, they are still small.

Seeds sent to The lab from the second cross, I've heard nothing, likely they are done for.

I thought I'd share a recent photo of the mother plant, stronger color than usual, bloomed in higher light, a little peloria evident. I have seen clones of Cattlianthe Golden Wax 'JF' that look similar to mine (though this is NOT that clone)

Well, I spoke too soon about my second cross (see post from 6-20-2014). I checked with Rockbridge Lab today and there are just a few protocorms developing in one of the flasks!

Sometimes they can be slow to start.

Update - I still have a few seedlings growing in a community pot, inside one of my seltzer bottle terrariums, sitting atop sphagnum moss.

Well - I should probably say "alive" rather than growing. Growth has definitely slowed or stalled. There are good roots for the size of the plant, but the leaves are still very tiny (about 0.5 to 1 cm max leaf length). They don't look much different from the way they looked in my post on 02-01-2015.

They have been grown entirely indoors under fluorescent lights so far. Bright enough to bloom the mother plant the seeds came from, as well as Phals.

Any suggestions for getting the growth going would be appreciated.

All I could suggest is a seaweed tonic solution that may invigorate the roots and the leaves will follow. In bottles they grow relatively quickly in media because they have humidity and a good food source. Outside, until they acclimatize and get to a fair size, they are slow, especially if they dont know whether to live or not.

I have tried seaweed extract once, may try again. Thanks for the suggestion!

Sorry, but no. Closest I may get is moving the bottle terrarium over the lights for the shelf underneath. Might give that a try.

The experiment comes to an end

I have not updated this thread in a very long while.

After growth stalled I started the spring and summer with some very encouraging seedling growth after I transferred them to a pot with seedling bark and moved the to a shaded location outdoors. They were in their own screened enclosure to keep out the bugs, etc.

We had a storm that produced a lot of rain, and seedling rot followed. Soon after, squirrels ripped apart what was left of my outdoor nursery and scattered the remaining seedlings.

It was still worth it IMO. I learned a lot from the 3-year experience, and from my mistakes. I can't see trying it again anytime soon (maybe in retirement). It has greatly increased my admiration and respect for those that flask seeds, bring them to sufficient size to pot up, and raise them into seedlings which we buy from orchid nurseries. When you find an orchid that is $15 - $20, trust me, you are getting it for a bargain, considering the time and labor involved (even though I know profitable nurseries are producing their seedlings much more efficiently than I can).
