Bright light gray bark on a tall, tiered-branching tree reminiscent of a birch, iigiri tree produces glamorous pendent clusters of red berries in fall and winter. Deciduous and native to central and western China and southern Japan, it has large, glossy, irregular heart-like, green leaves with whitened undersides. In early summer fragrant yellow-green flowers without petals dangle downward from the branches. Plants are dioecious, either being male flowering or producing only female blossoms that, when pollinated, will become small round, satiny red fruits. Already beautiful to behold in late summer as the berries turn red among the leaves, it becomes more spectacular if the foliage turns yellow, although not reliably in some regions. In winter, the architectural and horizontal branches radiate outward with resplendent stringed bunches of red berries for ornamentation.
Grow in full sun in well-drained but average to moist soils that are not alkaline. It is tolerant of nutritionally poor soils, drought and summer heat. It looks best located in a wind-protected spot among other trees, especially dark foliage conifers that will be a perfectly contrasting backdrop for the light bark and red fruits in winter. It is a terrific specimen tree for open woodlands or parks and campuses. To enjoy the female tree's red fruits annually, plant a male flowering tree nearby to ensure the dangling red clusters form on female plants. (source: learn2grow.com)

| Useful Info | |
| Germination | The seeds of this tree should be stratified for 6 weeks to break dormancy. Stratification is a cold treatment that occurs naturally over winter but can be imitated in a refrigerator in any season. Please use moist vermiculite or sterile soil and airtight container or zip lock bag. The seeds should be covered only very lightly when sown after the pretreatment. For best results, the soil should be between 15C and 22C. Germination usually occurs between 10 and 28 days. Seeds may sprout in cooler or warmer soils but may take longer or have a lower germination rate. (info source: soolca.com) |
