I took a small clipping from a friend, and within 4 weeks it went from 1 ft to 4 ft and blooming like crazy! Gorgeous full yellow flowers with red speckles.The flowers bloom one or two at a time then fall off quickly..many more are still coming..It has very dark green round shaped leaves. At first I thought it was a Gladiola type flower. I dont think so now. Then I thought Lily. Any one out there have a clue? I live in south florida and this plant is thriving outside in my patio.
