Acer palmatum Kenbu is a rare dwarf maple that has thin green leaves in the spring. The bark is a dark reddish color which provides a beautiful contrast to the light green leaves and makes this cultivar very unique. Additionally, when most maples with pink-red spring growth turn green in the summer – Kenbu is the opposite. The leaves start out green and sometimes turn red in the summer. The first one I saw was in 2017 and I was hooked – it was stunning. I began my quest to grow Kenbu and share it with other maple-lovers.
A moderate growing maple – Kenbu may add 5-8″ of new growth per year with good growing conditions. Remember a Japanese Maple need good drainage. The most important aspect of planting your maple is the right location with good drainage. Planting in a hole in clay soil can be a killer.
