Coastal Bonsai Care

Coast redwood

Sequoia sempervirens

Sitka spruce

Picea sitchensis

Western hemlock

Tsuga heterophylla

Kew accepts Tsuga heterophylla and places its native range from southern Alaska to northern California. Oregon State lists Zone 6, direct bonsai use, nurse-log rooting, and Thorsen's Weeping; NC State lists Zones 5a-8b and seed, stem cutting, and layering propagation; USDA Silvics and FEIS ground the humid Pacific Coast / northern Rocky Mountain ecology, root pathogens, defoliators, and rare mountain-hemlock hybrid note. Mirai has dedicated western-hemlock-design coverage plus Tsuga pruning, potting, and elongating-conifer fall-work method.

Coastal Douglas-fir

Pseudotsuga menziesii var. menziesii

Kew accepts Pseudotsuga menziesii var. menziesii and places the coastal variety from southeastern Alaska to the western United States. USDA Silvics distinguishes the coastal variety from var. glauca, while Oregon State and NC State ground Pacific Coast hardiness, cultivar labels, heat and humidity limits, and Douglas-fir / Oregon pine / red-fir naming. Mirai has direct Douglas-fir redesign, styling, pinching, pruning, and post-harden pruning coverage.

Monterey cypress

Hesperocyparis macrocarpa

Japanese cedar / sugi

Cryptomeria japonica

Hinoki cypress

Chamaecyparis obtusa

Sawara cypress

Chamaecyparis pisifera

Kew accepts Chamaecyparis pisifera and places it in Japan. Mirai direct Sawara coverage is thin, so the species page transparently transfers Chamaecyparis false-cypress method from Hinoki and related coastal conifer files, then grounds cultivar, hardiness, pest, and disease facts in Kew, NC State, Oregon State, RHS, and Purdue sources.

Lawson cypress / Port-Orford-cedar

Chamaecyparis lawsoniana

Kew accepts Chamaecyparis lawsoniana and places it from southwest Oregon to northwest California. Mirai direct Lawson coverage was not found, so the species page transparently transfers Chamaecyparis and coastal-conifer method from Hinoki, Sawara, Thuja, cypress, and elongating-species files, then grounds hardiness, cultivar, and Phytophthora lateralis risk in Kew, NC State, Oregon State, RHS, Oregon Encyclopedia, and USDA Forest Service sources.

Italian cypress

Cupressus sempervirens

Kew accepts Cupressus sempervirens and places it from the eastern Mediterranean to Iran. Mirai has direct Mediterranean collected cypress coverage plus Cupressus repotting method, so the species page grounds design and root timing in Mirai, then uses Kew, NC State, Oregon State, RHS, UF/IFAS, and UC IPM for identity, hardiness, cultivar, and disease context.

Nootka cypress / Alaska cedar

Callitropsis nootkatensis

Kew accepts Callitropsis nootkatensis and places it from southern Alaska to northwestern California. Mirai has direct Alaskan yellow cedar mentions plus transferable Thuja, Chamaecyparis, Cupressus, and coastal elongating-conifer method; the species page grounds hardiness, cultivar, cool humid habitat, yellow-cedar decline, shoot blight, and synonym handling in Kew, Oregon State, NC State, Missouri Botanical Garden, and USDA Forest Service sources.

Western redcedar

Thuja plicata

Kew accepts Thuja plicata and places it from southern Alaska to northern California. Mirai has direct Thuja plicata styling and summer-pruning coverage plus genus-level Thuja method; the species page grounds western redcedar labels, Zone 5 to 7b context, cool moist habitat, full-sun bonsai cultivation, cultivars, propagation, dieback, leaf blight, and forest ecology in Kew, Oregon State, NC State, USDA Forest Service / NRCS, British Columbia forest-health, and Pacific Northwest Pest Management Handbook sources.

Incense cedar

Calocedrus decurrens

Kew accepts Calocedrus decurrens and places it from western Oregon to northern Baja California. Mirai direct incense cedar coverage is limited to a scattered mention, so the species page transparently transfers cypress, Thuja, false-cypress, coastal-conifer, and elongating-species method, then grounds identity, hardiness, dry-summer ecology, propagation, and disease context in Kew, Oregon State, NC State, USDA, Oregon Encyclopedia, and Purdue sources.
