Ironic! Around here geraniums seem to grow like weeds and almost as hard to kill. I have a couple in 'suspended animation' in the basement right now. Doubly ironic considering they are supposed to like slightly acidic soil around 6.0pH and our water comes out of the tap pretty alkaline at around 8.2. I try to use rainwater, but that usually dries up around June / early July so if they want anything until ~December, it has to come from the hose!
On the other hand - of the few Venus flytraps I've had, they never looked better than the day I bought them and went down hill regardless of care, light, water...even flies, or any other amenities offered!
Maybe I'll have to try a new batch - I thought by now they would breed them to have 5-6 inch 'traps' and catch small mice/squirrels, etc!
