Yeah Harmandii doesn't act like a typical amorphophallus it seems. My konjacs are growing like crazy.
The weather here in the San Diego/Tijuana area is crazy. Several days it's in the 80s in the day and 60s at night so the bananas get all excited and then it goes back to mid 60s and 50s at night and windy so my TCs never know what's up. It's lack of consistency that frustrates me. The more established bananas don't care but the TCs need consistency I think.
At least my gladiolas and tigridia are blooming now.
Of course like you, I like the more exotic plants like aroid and nanners.
