Very nice one! I got one last year as a "bag baby". It is now about the same size as yours so I hope for buds soon! (What size pot is yours in?)
I have the 'Chi Ruby' clone. I haven't seen that one yet. Does Mei mean Ruby in some Asian language (Chinese or maybe Thai?) I have seen the 'Chi Mei' clone online.
I would have given $27 for that one as well!
