I love this plant. When I first got it, it was a sad little black stemmed bulb, with only two half burnt leaves. I put it on the porch at first, half day of sun. As I realized this plant loves the sunshine, I moved it to the yard out by the Avocado and the Hibiscus and it is really thriving. During really dry times, no rain, I water this plant with filtered water or saved rain water. I have not fertilized this plant since July.
