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 ;)

Greetings from Austria

[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.
