Why are there so few leaves in Lagerstroemia indica?

1, the growth habit of Osmunda japonica Thunb. is a perennial plant, and its growth speed is relatively slow, so the leaves are not fast and the number is small.

2. Osmanthus fragrans has long purple leaves, so there is not much need to increase it. The size and growth morphology of leaves are also affected by many factors such as the variety and growth environment of Osmunda japonica.
