zone 9 I'll post a pic when I can....thanks

It could still be another type of grass - a non-woody one. There is all manner of grasses including even bamboos that aren't woody.

Embothrium-

I considered that as a possibility, but, on enlarging the picture, it appeared that both pots had small culms that looked like bamboo. What do you think?

I think we need to see more of it.

The picture looks like some type of Muhley. Hard to tell without a better close-up of the culm.

Otatea acuminata (dwarf).Mexican weeping bamboo.Is my guess.You say it does not get that big.So my guess is it is the dwarf variety.

That's it, thanks, looks exactly like the original grove.

My pleasure Bob.Glad I could help.
