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. The first set of leaves they produce are called cotyledons.
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.
You can make the tree grow taller if you stake the branches upright. 'Viridis' has bright-green, dissected leaves that turn golden-yellow and red in the fall. This is the 'green-leaf' variety of the weeping Japanese maple. It has the same sun and soil requirements as the other red laceleaf maples.. . . . .364011233801!]0000000000000009783314147729!]
