Feb 17, 2012 BABY CACTUS I am enchanted by this baby cactus necklace. Lauren Serota gave it to me as a Christmas gift and yes, it actually is a necklace. It is to be watered every three months by simply soaking it in a glass of water for 30 mins. I enjoyed watering it so much! It has me thinking, I am going to try growing cactus from seed! How exciting will that be, baby baby cactus, and lots of them!
