One appears to be a deeper green in colour.

I am guessing they are both Pseudosasa japonica... They are probably
the "mother" (i.e. normal) variety... Definitely not the 'Akebono'
subspecies which is similar but has varigated leaves.

These are a running type that will go under your fence at some point.
Luckly, they are relatively slow to spread and easier than many to
contain. HOWEVER, they will invade nearby areas eventually. And with
nothing to prevent them, it can be as little as a few years.

Do a Google search for Pseudosasa japonica for more info, and/or look
