i had a cut lone rose in a vase i forgot about for a couple weeks. when i looked at it again, i found that the bud was dried up, but a new bunch of leaves had sprouted from the stem!
the water is the same.... old water.
so what's happening?
can i actually... grow a rose plant from this? how?
there are no roots, just the same old stem... weird man.

Never heard of such a thing .. It is indeed unusual to say the least !
