Elegantissima ambig. tends to grow best in a soil ph of between 4.8 and 7.5 meaning it does best in moderately acidic soil - weakly alkaline soil.

Ensure that temperatures are mild and all chance of frost has passed before planting out, as Elegantissima ambig. is a hardy plant.

It was first discovered (by Euro-Americans) near Port Orford in Oregon and introduced into cultivation in 1854, by collectors working for the Lawson & Son nursery in Edinburgh, Scotland, after whom it was named as Lawson Cypress by the describing botanist Andrew Murray². The USDA officially calls it by the name Port Orford cedar, as do most people in its native area, but some botanists prefer to use the name Lawson cypress (or in very rare instances Port Orford cypress) instead. The name “Lawson’s cypress” is widely used in horticulture². This tree has many botanical synonyms, but the current officially-accepted name is Chamaecyparis lawsoniana¹².
