Savia divinorum is not something I have grown since I lived in Florida where the weather was most conducive to growing it. So, I really can't say I could grow it here having not tried. Sometimes our natural climate makes us a better gardener than we might be otherwise. Or... one could argue that there is simply a learning curve anytime one moves to a new climate.
Suffice it to say, my big love is cacti. I love em and hold em and squeeze them till they pop into multiple grafted specimens if I love them enough. Other than that, I also propagate a few roses from cuttings, hybridize hemerocallis for fun... nothing serious at the moment. However, I'm one of those that can't see a flower bloom and not cross it to something else which has resulted in a few of my old seedlings being named by others that thought them worthy of introduction.
I hope to see your collection grow as well as our shared knowledge here with your presence as it is always good to see new faces and new perspectives.
