Are y'all sitting down? I water all my plants with tap water from a hose. Even my Nepenthes. Momma Nature does some watering though, particularly this month. We badly need to do some drying out.
Jacquie, if you want a really, really easy bromeliad to grow inside (outside, under trees during the spring and summer if you wish), grow the "urn plants". I just cannot imagine any plant being easier to grow.
Tiffany, the only Tillandsia that remains outside is the Spanish moss. I left out several other varieties last winter, just to see if they would survive (only one of each variety except for some ball moss), and I lost everything. I do lose some Spanish moss (the experts say it is impossible to grow them here), but the majority survives and really flourishes during the spring and summer months. Heck, some of that moss gets so long, I have give it a haircut so that I can walk beneath it so that it won't knock my hat off.
