Fun Facts
- 🌱 Japanese Sweetspire is actually native to the southeastern United States (Virginia to Florida), not Japan—the common name reflects historical trade routes and naming conventions.
- 🌱 The fragrant flowers attract not only pollinators but also produce a delicate honey-like scent that intensifies on warm spring mornings.
- 🌱 The 'Little Henry' cultivar was selected specifically for its compact, dwarf habit, making it much more suitable for modern smaller gardens than the species plant, which can reach 6-8 feet.
