Tee, I grew a pineapple for nearly a year. Realized it wouldn't flower for another year, so I gave it away. Never learned if it ever had fruit. I'm too impatient for results, I guess. My grandmother used to grow a sweet potato suspended in water with toothpicks. It would trail all over her screened porch. I tried it once and wasn't successful. I think they use a growth inhibitor on most all potatoes now so they won't sprout. I'd hate to think it was my brown thumb instead!
