|I see advertised a Park Seed Ilex Crenata (Sky Pencil)
One thing not mentioned but very important is what zones will this tree thrive in. Perhaps you could tell me. THANK YOU SO MUCH, Steve in northcentral Indiana.
|You're in USDA zone 5 and Sky Pencil holly is rated only as low as zone 6 so I'm afraid it won't work for you. A plant with a similar appearance is Emerald arborvitae (Thuja occidentalis 'Emerald'). It grows in zones 4-8, has a narrow upright form with rich emerald foliage. It is evergreen, grows in full sun and reaches 15' tall by 3-4' wide.
Hope you find just the right plant for your landscape!
