Description

The Chamaecyparis lawsoniana 'Ivonne' is one of the most colourful varieties of conifers with its very intense lemon yellow evergreen foliage. This highly ornamental tree has a conical, compact habit with upright branches, making it ideal for creating beautiful privacy hedges that are resistant to sea spray, pollution, and cold weather. With slow growth, it requires little pruning. Its moderate development also makes it suitable for individual planting, even in smaller spaces. This low-maintenance plant will thrive in sheltered locations with cool, fertile, deep, and well-drained soil.

The Lawson Cypress, sometimes called false cypress, is a majestic conifer of the Cupressaceae family native to the moist coastal forests of the northwest United States. In its natural environment, it often reaches heights exceeding 30m (98.4ft) with a trunk diameter approaching 1m (3.3ft). It has an upright, conical habit, and its pendulous branches form soft curtains adorned with fairly dark, bluish-green foliage. It has given rise to numerous cultivars, including a wide range of plants with more modest stature, better suited to the size of our gardens.

The 'Ivonne' variety is a very beautiful form of this species that will not exceed 5m (16.4ft) in height and 2m (6.6ft) in width. From a young age, it exhibits a conical habit that is slender, narrow and very dense, supported by upright branches emerging from the base of the trunk. Its slender and flattened branches are densely covered with lemon-yellow scale-like leaves that turn slightly green during summer heat and on shaded parts of the foliage.

The Chamaecyparis lawsonia 'Ivonne' can be used as a hedge, as a specimen, or planted in a grove in a medium to small garden. It does not require pruning, but can tolerate light pruning. With a strong presence and a distinct personality, it is quite challenging to associate with other large shrubs, but it works well as a neutral-coloured screen at the back of shrub or perennial beds. The architectural qualities of conifers deserve to be more frequently used in our gardens, where they provide permanent structure. These plants are discreet in summer but assert themselves in winter when other flowers have deserted our gardens.

Chamaecyparis, False cypress: planting, pruning and caring for

Read article

Chamaecyparis are among those conifers with dense, scaly foliage appreciated for the making of hedges, notably the Chamaecyparis lawsoniana species, surprisingly used in its typical form. It is nevertheless one of the conifers that has produced the greatest number of cultivars (over 200!) such as Alumii with very compact, bluish foliage and a conical form of 3 to 4.50 m or Ellwoodii, much used in hedges. The wild form, capable in cultivation of reaching 36 m in height with a trunk of 1.20 m diameter, comes from the north‑west United States, like the giant Thuja. Its branchlets, tinged dark green or bluish green, with slightly trailing tips, give it a remarkable, somewhat phantasmagorical undulating appearance while its variety Aurea Densa forms a spectacularly compact golden column. Sawara cypress (Chamaecyparis pisifera) and Japanese Hinoki cypress (Chamaecyparis obtusa) also offer a range of dwarf or moderately vigorous cultivars, with filamentous or, conversely, blunt branchlets, with a fern‑like habit (<a href="https://www.promessedefleurs.ie/shrubs/conifers/conifers-by-variety/chamaecyparis/chamaecyparis-obtusa-teddy-bear-hinoki-cypress.html">C. obtusa Teddy Bear</a>), acidular in <a href="https://www.promessedefleurs.ie/shrubs/conifers/conifers-by-variety/chamaecyparis/chamaecyparis-obtusa-wissel-hinoki-cypress.html">obtusa Wissel</a> in very attractive golden, bluish or intense green colours. The word 'Chamaecyparis' is derived from Greek and means 'cypress‑shaped', given the strong resemblance of its conical habit and its aromatic foliage made of small imbricate scales. However, Cupressus occupy dry, sunny southern areas while Chamaecyparis grow in sheltered, moist, often coastal areas. Chamaecyparis are not demanding about the nature of the soil, provided it is fresh, well‑drained and not excessively calcareous. The species lawsoniana shows a strong susceptibility to the Phytophthora fungus that decimates its wild population in the United States as well as in gardens where the disease is often spread by nurseries. And although they prefer fertile, deep humus, they adapt to less favoured ground, with moderate growth and reduced luxuriance. Avoid pruning them as much as possible.

Planting and care

The Chamaecyparis lawsoniana 'Ivonne' is planted in spring or autumn in a light fertile soil, rich in humus, sandy, slightly acidic, neutral or slightly chalky. This conifer thrives in the sun (in a fairly humid climate) or in partial shade. Water the plants regularly during the months following planting. This conifer is not too demanding of soil quality, but it suffers in dry soils and climates. It is a species of cool, oceanic or mountain climates. This tree does not require pruning, but it can tolerate it if kept light: shorten the young branchlets without going back to the old wood.
