Keep in mind when planting that Sulphurea aurea is thought of as hardy, so it can be safe to leave outdoors for the majority of winter (although if in doubt, using a row cover is often a good idea).
Ensure that temperatures are mild and all chance of frost has passed before planting out, as Sulphurea aurea is a hardy plant.
The genus name Cupressus is Latin for “cypress”, while glabra it Latin for “smooth”.
