I put seeds in little pots of dirt and then forget what I planted. I finally figured out one new plant is a papaya. I have kumquats and magnolias that are now over 6 ft tall after about 8 years. Here is a mystery plant that is several months old. It develops tiny black berries and then tiny white flowers and now it has this green bulb thing. Does anyone know what this is? After the 3 photos of the mystery plant, I also attached my papaya, kumquats, and magnolias just because I love them and am amazed that they grew. I had a nice harvest of kumquats last April and now I see new buds that will turn into white flowers that will turn into kumquats. Delicious. So exciting for someone who doesn't know what she is doing. Back to my mystery plant. It has to be from something I ate. When it first sprouted, the seeds were so tiny I could not tell what they were when I moved it to a larger pot. What is this?
