🌿 Description

Arborvitae are dense, pyramid-shaped evergreens native to North America and well-adapted to Kansas landscapes. Their flattened sprays of scale-like foliage stay vibrant green throughout the year, providing texture and color even in winter. Mature plants can reach 10–40 feet tall depending on variety.

🌾 Growth Habit & Conditions

• Soil: Prefers moist, well-drained soil but tolerates clay once established

• Water: Regular watering during the first few years; drought-tolerant after establishment

• Hardiness: USDA Zones 3–7
