I have what I think is Italian (or Israeli) Ruscus foliage. It came in a floral arrangement sent to me. The flowers have long died but the two stems of this plant are not only (what seems to be) rooting (I've kept vase full of water) but the dot/bump on the back of mature leaves seems to have a tiny growth...the light colored bump has a tiny stem coming out of it. What is going on? Can I plant the 2 stems in soil? Maybe use a leaf with the growth (new sprout) on it? Thank you!
