Yesterday I fed it another large drop of blue food coloring and a juicey fly. 5 traps fed that way so far.
It has been growing indoors, under fluorescent lights. Today I am moving it outside, where many of my other VFTs are sending up flowers.
PS: I am also thinking about trying something with professional food coloring - the kind you have to buy at a Cake Shop. Either liquid or paste form. What fun!!
