Fun Facts
- 🌱 Japanese Larch Pendula is one of the few deciduous conifers commonly grown in temperate gardens; its needle drop in fall is a spectacular golden display before winter dormancy.
- 🌱 The weeping form 'Pendula' is a grafted cultivar, typically grafted onto an upright Japanese larch rootstock at varying heights (often 6-8 feet) to create different silhouettes—weeping standards create dramatic 15-20 foot tall weeping fountains.
- 🌱 Larch wood is prized in traditional Japanese construction and woodcraft for its strength and durability; the ornamental cultivar 'Pendula' honors Japan's forestry heritage while serving purely decorative purposes in Western gardens.
