Growing Japanese Maples from seed is a slow but highly rewarding process. In two to three weeks if the weather is warm, you should see seedlings start to pop up.
Most Japanese maples grow at a slow to moderate rate of 1 to 2 feet per year. They typically grow fastest when they are young and slow down as they reach maturity. Planting them in a spot where they are happy and caring for them well helps maximize their growth rate.
Tamuke-yama is the fastest growing of the cascading forms. It is also the most heat resistant and so the ideal choice for hotter, humid areas. The leaves are reliably purple-red all summer, turning crimson in fall.. . . . .364011234862!]0000000000000009783314144922!]
