Moso colour culms and upsize

I bought this Phyllostachys edulis a few years back as edulis bicolour but I was convinced it was standard green edulis but now I am getting culms coming up 10x the size of the plant with yellow culms what’s your thoughts please

I'm scratching my head with this one as none of the tiny culms have any yellow coloration or hints of stripes as far as I can tell.

Edulis is notoriously difficult to propagate - maybe this division fell back to a juvenile-like state?

I am guessing that the new, yellow culms do not have a green sulcus?
The Bamboos of the World lists a " Phyllostachys edulis 'Lutea' " syn? 'Aurea' with yellow culms - that would be great luck if it is indeed one of those.

I could also imagine someone grew a seedling that had this yellow culm coloration (a rare but not entirely implausible event, edulis 'Colombo' is a seedling http://www.bambus-lexikon.de/phyllostac ... lombo.html and so is Ned's 'Gold Stripe') and simply called it bicolor.

Thanks for sharing and please keep us updated how the plant evolves ;)

[edit]
The last explanation I may have is that this is not bicolor but rather nabeshimana - that form does also produce green culms with only a few yellow stripes here and there and culms that look like bicolor (which would explain the confusion)

Deane,

from bamboos of the world it appears that pubescens f. holochrysa is synonymous to the lutea.
I suppose it will show its true colors soon enough given the upsize.

Maybe the person that sold you the plant can give you more information on its origins or maybe some pictures of the parent.

Hi

It could be a sport off your bicolor. This does happen. My friend has a moso doing the same thing this year with multiple variety in the grove.

I grow gold stripe and I also am blessed to grow tao kiang aka nabeshimana. The nabeshimana is a named seedling with amazing stripes. No other Bamboo compares IMO. Gold stripe is kind of boring. It does show lots of different faded stripes though.

I am really hoping it’s a gold form of moso. There are a few out there that are gold. The “real” holochrysa is amazing amazing bright yellow gold. It’s untouched in beauty.

Moso’s are very hard to propagate. It will be a difficult choice to seperate it and see if your bright shoot will be stable.

I'll just cite this from bamboos of the world:

Deane, I think it will still take a bit of time to get a definitive answer as the plant kind of is showing juvenile characteristics and needs some upsizing/maturing

According to bamboos of the world tao kiang and nabeshimana are not the same cultivars.
Given that striped mutations do apparently occur here and there (i.e. goldstripe) I wouldn't be surprised that this is the case, however then you'd have to add the factor that nurseries and collectors may have used the names interchangeably. I would avoid calling nabeshimana a named seedling although it probably originated as such, since the cultivar is quite old (Bamboos of the world has this to say on nabeshimana:
Distribution: JAPAN: in cultivation, rare; originally found in Yamegun, Fukuoka Prefecture, in 1934 (H.Okamura & al., II1. Hort. Bamb. Sp. Jap., 1991: 344).
)

All the best,

Nicholas

Agree with Nicholas, several years ago I had a few Moso seedlings in the ground, some showed heavy variegation each spring but all faded to solid green during the year. None ever matured at a satisfactory rate so I killed them all off but each spring it was variegated new leaves fading to green.

Nicholas,

Japan names their’s nabeshimana and China uses tao kiang ( synonyms ) . I believe they are the same when discussed. Nabeshimana is said to be green with yellow stripes and the opposite for tao kiang hah. It’s kind of like asking if a zebra is black or white stripes I guess. Both show characteristics of more green and or more yellow on individual culms around the groves.

I’m growing the true nabeshimana. It’s not it a seedling that looks similar and was named that way. I see a guy in Seattle claims he has nabeshima but the culms are nothing like the true form. It’s proably a seedling mutation.
