The Story
Plant Bio
Platycladus orientalis 'Conspicua', also known as Oriental Arborvitae, is a dense, conical, evergreen conifer. It is noted for its vibrant, golden-yellow, scale-like foliage that holds its color well throughout the year. This cultivar is distinguished by its bright golden-yellow foliage, which provides excellent year-round color. Its formal, upright habit makes it a great choice for specimen planting, hedges, or screens.

Common Questions
Oriental Arborvitae questions
What zones can Oriental Arborvitae grow in?
Oriental Arborvitae is hardy in USDA Zones 4–9. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.
Is Oriental Arborvitae deer resistant?
Not reliably. Deer may browse Oriental Arborvitae, especially tender spring growth — plan on repellents or fencing where pressure is high.
When does Oriental Arborvitae bloom?
Oriental Arborvitae typically blooms in spring through late fall. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Oriental Arborvitae need full sun?
Oriental Arborvitae does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
Is Oriental Arborvitae drought tolerant?
Yes — once established (usually after the first full season), Oriental Arborvitae handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
