I don't know if there is more than one species. I'm still learning.Can't wait for mine to get that big. I hear though that there are two different species out there, and that one of them stays smaller. You have any experience with that? I also love that lillie you have, what species is it?
Yes, they are all close in color except the new leaves (as you would expect) which start out a very light green.Hm, I'm surprised that all the leaves on your plant look the same green color.
