Sometime ago, John gave us a can labelled Music Tree. According to the instructions, it contained seed(s) and planting medium. All we had to do was open the top and bottom of the can and add water.
[Instant plant: Just add water]
[Close-up of the seed: Looks like a mini chickpea (kacang kuda)... don't know if there're more inside the planting medium]
It has a shelf-life and since it is going to expire soon, we started adding water today. Interestingly, there must be some special chemical in the planting medium because the whole can felt warm after adding the water. The seed is supposed to germinate in a few days. Will post updates.
