A large, conical tree with yellow leaves in spring, maturing to yellow-green in summer before turning yellow in autumn. The young branches are orange-yellow, providing a spectacular show in winter. Red-pink catkins are a source of pollen for bees in early to mid-spring. Fixes nitrogen in the soil, so good for improving soil conditions for other plants.

The grade size is the size of the bag/pot the tree is in. This is measured in either litres or pints per bag.

The height is the overall height of the tree from the top of the pot/bag (bottom of the trunk) to the top of the tree. Some grades have height ranges as the heights of the individual trees vary.

The standard height is the height of the clear trunk from the bottom of the trunk to the graft or the first branch (if it is not grafted).

Grades that are in production are not yet ready for sale. You can place a pre-order for a 50% deposit and we will hold the stock until it is ready. Enquire if interested.

Prices subject to change without notice. Actual stock quantity may differ. Every care is taken to accurately record heights but due to slightly different growth rates and other natural variables that can occur within and to a species, variety, or cultivar, the actual height of the final product may differ from what is stated.
