Chamaecyparis obtusa Lucas - Hinoki Cypress

Chamaecyparis obtusa 'Lucas' is a dwarf conifer from the Cupressaceae family. This variety of Hinoki cypress from Japan is remarkable for its delicate foliage, reminiscent of certain ferns. Depending on the amount of sunlight, it takes on a beautiful yellow to yellow-green colour, which adds to its ornamental interest. Slow-growing, it generally reaches a height of about 1.5m (5ft) with an equivalent width. It adapts to slightly acidic to neutral soils, which are cool and well-drained. A sun or semi-shade plant, tolerant of maritime winds, it is also extremely cold-resistant (-25°C (-13°F)).

Its evergreen foliage is finely arranged like the fronds of certain ferns, and is yellow-green to golden yellow. The young shoots are white at the base before turning yellow. Slow-growing, it forms a more or less regular ball of about 1m (3ft) in all directions after about ten years. Its final size reaches a maximum of 1.5m (5ft), making it ideal for rockeries or container cultivation. Its delicate architecture may even inspire shaping it into a pseudo-bonsai to integrate it into a Japanese garden. Like most of its counterparts, it requires neutral to slightly acidic soil, which retains moisture in summer while being well-draining. It will thrive in different exposures, sun or semi-shade, as long as it avoids too much direct sunlight that could damage its foliage; so be careful about this point in sunny climates!

Its refined aesthetics and small dimensions make it particularly suitable for rockeries, provided that the soil is not dry. It will also be at home in a contemporary garden, planted alongside other colourful or erect plants. For example, plant Juniperus scopulorum 'Skyrocket' behind it to contrast with its height, columnar habit, and bluish foliage. Purple shrubs will also elegantly blend with this variety, making sure to choose low-growing varieties, such as Loropetalum chinense 'Ever Red' (in not too cold climates), or a beautiful Japanese maple (in semi-shady conditions).

Hinoki is the Japanese name for Chamaecyparis obtusa and means "fire tree" because it was once used to generate fire by rubbing its wood. Japanese cypress wood has been used for the construction of numerous buildings such as temples. An essential oil with soothing effects is also extracted from it.
