I saw my one the other day and thought the same, that I should trim those long stems and plant them again. They hang down, with those brown thin roots and scream to be repotted 😂
And the colour - the same difference here, if on sun or not, but my gets less sun so it stays more in a green-blue version. The little yellow twinkle twinkle stars are so cute ;))
They grow really fast, dont they? :)
I dont quite mind the long stems, just that it gets too long and I keep kicking it (the pot stands on the floor). Maybe I will just put it in a hanging basket then they can hang as much as they want to :P
My ones gets direct sun almost all day long. I have another pot that I keep in a corner and it is more like yours. More blue and with longer leaves.
