Iseli Nursery Introduces Five New Hybrid Japanese Maple Varieties

Iseli Nursery, a wholesale grower based in Oregon, has released the Pacific Rim Collection, a line of five hybrid Japanese maple cultivars. The nursery spent two decades selecting, breeding, and evaluating these trees before making them available. The collection includes Wabi Sabi, Origami, First Flame, Final Fire, and Cascadia. Each variety offers specific characteristics for gardeners in the Pacific Northwest region.

The nursery advises planting these trees in soil with adequate drainage to prevent Verticillium Wilt. This fungal disease resides in the groundwater and infects roots during wet winter months. There is no cure for the infection, which often kills affected maples. Gardeners can diagnose the issue by sending soil samples to an analytical lab. They can also inspect dead limbs for a blackish bullseye pattern in the cross-section tissue. This pattern indicates that the vascular system has been cut off from the root system to the crown.

Wabi Sabi is a weeping lace leaf variety with green foliage and bright red seeds. It displays gold, orange, and red colors in autumn. The tree matures to approximately 7 feet in height and 10 feet in width. It functions as a specimen plant for sunny or partially shaded locations. The variety cascades over rocks or berms and provides winter interest through its branching structure. Pruning can control the height, though the tree requires adequate room for its spread.

Origami features delicate green foliage that turns orange to yellow in autumn. The tree maintains a rounded globe shape with sturdy branching. It grows to about 8 feet in both height and width. The foliage resembles small paper cranes. The variety is suitable for container planting or the ground in sun or partial shade. Its dwarf status makes it a manageable option for smaller garden spaces.

First Flame is a larger, faster-growing cultivar that reaches 20 feet in height and 15 feet in width. It produces flaming orangey-red foliage in spring. The leaves transition to green with red hints during the summer. The tree displays a blend of colors in the fall. The variety has a narrow vase-shaped form and smaller foliage. It is a popular choice for sites where a larger presence is desired.

Final Fire is another large grower that matures to 20 feet tall and 15 feet wide. It has a more rounded form than First Flame. The spring foliage is a pastel mix of yellow, light green, and pink hints. The leaves turn crisp green in summer. The fall color begins with orange tones, shifts to wine, and ends in a fire engine red hue. The tree has sturdy branching and superior hardiness. It thrives in full sun or partial shade.

Cascadia displays lace leaf foliage on a broad tree or large shrub. It does not weep like typical lace leaf maples. The intricately dissected leaves emerge green in spring and hold their color in sun or partial shade. The foliage turns golden-orange before winter. The tree reaches 7 feet in height and 10 feet in width. It offers a sturdy branching structure and an Asian-influenced aesthetic. It serves as a focal point in the landscape.

Local garden centers continue to stock these varieties as they prepare for winter dormancy. Planting in the fall allows the trees to establish before spring. The Pacific Rim Collection provides options with distinct foliage, habit, and color throughout the seasons. Gardeners can select cultivars based on desired size and color profile.
