Araucaria araucana (the “monkey puzzle tree”) is an evergreen conifer with an instantly recognizable style: an upright trunk and tiered branches, covered with stiff, triangular leaves. Highly decorative as a standalone specimen, it provides a strong year-round presence and, over time, becomes a true landscape tree. It is best suited to gardens with enough space and well-drained soil, in climates that are not too dry in summer.

Larix gmelinii var. olgensis (Olga larch / “Olga Bay larch”) is a deciduous conifer: it carries green needles in spring and summer, then turns a beautiful yellow in autumn before shedding. Very hardy, it thrives especially in climates with cool summers and cold winters. Its young conical shape becomes broader and more expressive with age, making it an excellent architectural tree for large gardens and parks, in soil that stays moist but well-drained.

Larix laricina (tamarack / American larch) is a deciduous conifer: its green needles form a light, airy mass in spring and summer, then turn golden yellow in autumn before falling. Very cold-hardy, it appreciates moist (even waterlogged) soils, while still being able to grow in cool, well-drained ground. A superb structural tree for large gardens and parks, especially striking near a water feature.

Pinus aristata (Bristlecone pine / Rocky Mountain bristlecone pine) is a characterful evergreen conifer, appreciated for its blue-green foliage, very slow growth, and a silhouette that often becomes irregular and sculptural over time. It is an excellent architectural subject for cold or continental climates, in full sun and well-drained soil, even poor soil. Once established, it is fairly drought tolerant.
-

Pinus contorta (lodgepole pine / contorted pine) is an evergreen conifer from western North America, known for its outstanding adaptability: depending on its origin, it can grow as a wind-beaten coastal shrub or a slender mountain tree. Its needles in pairs, good tolerance of poor, acidic soils, and cones that often persist on the branches make it an excellent choice for naturalistic gardens, free-draining sites, or mountain-style plantings in full sun.
-

Pinus ponderosa (ponderosa pine / “western yellow pine”) is a large evergreen pine with a very recognizable style: long needles gathered in tufts, sturdy cones, and above all a mature bark that turns orange to caramel-brown, broken into large plates. It thrives in full sun, in well-drained soil—even poor, stony ground. Once established, it becomes an excellent structural tree, suited to spacious gardens and mountain or naturalistic settings.
-

Pinus rigida (pitch pine) is a characterful North American pine, valued for its toughness and its ability to grow where many trees struggle: sandy, poor, acidic soils, sometimes dry. Its dark foliage—thick, stiff needles in bundles of three—and a silhouette that often becomes twisted with age make it an excellent architectural conifer, particularly suited to naturalistic gardens, free-draining ground, and exposed situations.
