Item Description:
PICK-UP ONLY
This young tree was grown from seed sown in 2021. The seeds were from an ‘Aoyagi’ cultivar and were given to me by a man with a Japanese maple collection to die for (thank you Chong!).

Japanese maples can self- and cross-pollinate, thus while the female contribution to this sapling is ‘Aoyagi’, the male contribution is unknown. (Japanese maples also exhibit extreme genetic variation even amongst trees from the same mother tree.)

‘Aoyagi’ is known for its chartreuse-green bark and leaves, and these traits can be seen in this descendant.

The tree including Air-Pot is about 900 mm long and about 600 mm high.

Dimensions of the 4.1 L Air-Pot®:
Inside diameter: 233 mm
Outside diameter: 269 mm
Height: 115 mm

The top rows of cones is closed and act as a water reservoir.

Plant Description:
This four-year-old green-leaf Japanese maple (Acer palmatum) has great bonsai potential with its natural tilt, and the above-ground roots could possibly be trained in the ‘root over rock’ style.

Air-Pot containers create dense fibrous root balls as in the photos — these are not of this tree but of another maple grown in a 3 L Air-Pot container.

Bonsai enthusiasts love these containers for this very reason.

Please note that this tree is in the 4;1 L Small Seed Tray, and not the similar 4;1 L Bonsai Training Pot.

Growing Information:
Japanese maples grow well in a pot or the ground, and can handle from full sun to shade, though their native habitat is as understorey trees in shady woodland.

These trees grow well all over Australia, including more dry regions providing they have enough water. They are frost hardy temperate trees, and will survive winters colder than is typical of most places in Australia. I would not recommened these for tropical regions as they would not get strong enough signals to trigger winter dormancy.

Acer palmatum makes both a stunning bonsai as well as a striking landscape tree. The autumn colours of its leaves are wonderful to behold as it prepares to enter winter dormancy.
