Miniature plants have to look to scale when they are planted in a miniature setting. There are many plants to purchase that would work for a tropical look but I have killed more plants than I have kept alive and since the miniature ones are so expensive, I decided to try some from seed. These three plants are actually from seeds taken from full-scale plants in my outdoor garden. Since they are being grown in pots, and indoors, so far they have not gotten very big but each had the potential to be a normal size plant. It will be interesting to see what happens in a few months. The mimosa is a tree about 15 feet tall when mature; the blood sorrel has leaves about 12 inches long when full grown in late summer; the bamboo is a short variety, about 2 feet tall.
