Fun Facts
- 🌱 Gelderland Arborvitae is native to eastern North America but was selected and named in Gelderland, a province in the Netherlands, where it was cultivated for its superior golden color and hardiness.
- 🌱 The foliage intensifies to an orange-gold color during winter months due to anthocyanin pigment production as a cold-hardiness mechanism, creating stunning seasonal color shifts.
- 🌱 Arborvitae wood has been traditionally used for fence posts and shingles due to its natural rot-resistance, a property that extends to the foliage which deters many pests naturally.
