Frequently Asked Questions
Q1 What are the best plants for North Carolina gardens?
Carolina jessamine (the state flower), dogwoods, mountain laurel, and crepe myrtles are top choices. For the mountains, focus on rhododendrons and native azaleas. The Piedmont suits dogwoods, redbuds, and wild indigo. Coastal gardens thrive with yaupon holly, wax myrtle, and sea oats.
Q2 When should I plant in North Carolina?
Fall (October-November) is the best planting time for most of NC, giving roots months to establish before summer. In the mountains, spring (April-May) may be safer for cold-sensitive plants. The Piedmont growing season is roughly 200 days, extending to 240+ on the coast.
Q3 Which NC region am I in and why does it matter?
North Carolina has three garden regions: Mountains (zones 5b-6b), Piedmont (zones 7a-7b), and Coastal Plain (zones 7b-8b). Each has different soils, temperatures, and rainfall. A plant that thrives in Wilmington may freeze in Boone. Always check your zone before buying.
