Juniper Bonsai
Juniperus procumbens / Juniperus chinensis
📖 About this plant
The most popular bonsai species worldwide, junipers are coniferous evergreens with distinctive scale-like or needle foliage, attractive reddish-brown bark that shreds with age, and blue-green berry-like cones. Juniperus procumbens ‘Nana’ is the classic beginner bonsai. They excel in cascade, semi-cascade, and informal upright styles. Junipers must be kept outdoors year-round as they require a winter dormancy period.
