It may be shock because of the trauma it suffered, I am not well versed in philos but if the roots are healthy, it will bounce back, maybe with one leaf or two, or just the rhizome. But, if the roots are healthy, it will recover with care and patience.

those do not look like healthy roots to me. I've been growing P. gloriosum for sev years and it's rhizome (the older part of it) got bare. But it had roots going down along the whole length of it. So what I did, I just cut the the rhizome without lifting it or disturbing the roots and within a month I had 2 buds on leafless rhizome :). I think I left 1 leaf on it though, but it declined soon. it's doing fine, has small baby leaves on 2 shoots at once!

and then I wrapped long fiber sphag around the growing tip - where new roots form easily. they did grow too. and then I cut off the tip with 2 leaves and roots and it's doing fine now too. I am still not disturbing the original pot, as I like having multi stalks from 2 halves of rhizome instead of 1 growing tip.

I agree, that if you wrap your cut rhizome in LF sphag and keep it moist in wrapped plastic, it should regrow new roots. I would also tent the whole thing in plastic to increase humidity and reduce evaporation from leaves. They will decline as plant uses them to grow new roots.

your old rhizome should resprout too. Be patient, keep it in good light and warm and humid.

Just wanted to say HC mcdole that you’re mutant gloriosum is AMAZING. I hope it continues and maybe you can isolate it. People would probably pay big bucks for it. Wow.

Thank you, everyone!! I cut off the yellowing leaves, wrapped the rhizome and roots in damp sphagnum, and moss, and put the rhizome and moss in a Ziploc bag. So far it seems to be doing okay!

you should see new white tipped roots in a week :). when you plant use a shallow wide pot, as the rhizome just creeps on the surface. your prev pot was too deep and narrow.

you should not be replanting it for at least a couple of years. I use so called begonia hanging baskets. but most hanging baskets that are very wide on top and narrow on the bottom will do. However, they will be unstable since the leaves will get large. I have found that only when it's given partial sunlight in west or east window indoors it will grow normal petioles, otherwise they'll get very long.

you can put the shallow pot inside a glazed cachepot to keep it steady.

I recently cut my Gloriosum to give a piece to my friend. The cutting appeared to have good roots but the leaves are now yellowing!! Any ideas?

you need to wait..it uses nutrients from leaves to develop more roots..it takes 4-6 weeks to finally the new shoot to develop and start growing. you need to have patience. :)

Mcdole, any updates on your plant?

The pale part of the leaf didn't like the cold so it is almost gone now. Time will tell if the next leaf or two keep that mutant gene or not.

Thanks for the update!

Wow what a beautiful plant!! I have a Gloriosum on the way to me. Can’t wait to grow it.

I bought a Gloriosum about a year or so ago from a local nursery. Like normal it was in a small pot and needed re-potted. Did okay for a while - but then had problems with any new leafs would unfurl ripped up and torn looking. Plant thru time would have spans of good growth only to be followed with more struggling and leaf lose. I saw a YouTube video yesterday of a woman telling how she had tried the Sphagnum Moss process with good results. So this morning I carefully pulled up the rhizome and put it into a shallow bowl with warm moistened moss and covered with Ziplock bag. I hope it works!

leaves get torn and/or have problem unfurling is due to lack of humidity/moisture.

Although when in ground in tropical climate with high enough humidity it can be kept drier. Keep in mind that large leaves cause a lot of evaporation too.

when indoors in less then optimal conditions what I have resorted to on occasion is putting a plastic bag loosely on top of emerging leaf/shoot.

when I see that leaf edges are sticking while the shoot is emerging I wrap a damp paper towel around it to kept it unglue. you need to be very careful, as the leaf is very soft and it takes about a week for it to firm up.

alternatively you can mist it lightly ev day for a few days until it's ok.

Hc mcdole please keep is posted!
