vivax 'Huangwenzhu Inversa' turning red?
My precious 2 gallon Phyllostachys vivax 'Huangwenzhu Inversa' did not survive its first winter (It drowned), but while it was alive, I observed the clums changed from the nice pale yellow and light green stripe to dark yellow and near black stripe after I put it in the ground. I bought a replacement this spring, 5 gallons this time, and its already taller than my 3 year established Incense bamboo (astro-something). Anyway, the culms it shipped with looks like they have been through a war, but I just attributed it to a consequence of nursery life. The new culms its currently putting up are the nice pale yellow and bright light green stripe that are more like what I was expecting. However, its not even done branching out yet, and its starting to get redish blotches I fear will turn into more black battle scars. So what are these red blotches? And is it normal for this species to darken as it matures, and to what extent, should the light green really turn into a dark green/black color?

Not really relevant to the question, but after 3 years my atrovaginata looks more "large bush" than "timber bamboo"...
