They must be indeed....however, I find that extreme heat anmd dryness are not liked by the Arisaema--and that's what we've got at the moment. :-( Oh well, temps are due to drop to 14 degs during the day. It is 12 degs as we speak this evening! The temp here has dropped by more than half today.
Thanks Philip. Ain't it just. All I need to compliment it is an arrangement of tipsy pots and the confusion should be complete.
