Fun Facts
- 🌱 Despite its common name 'Japanese Sweetspire,' this plant is actually native to the southeastern United States (Virginia to Florida and Texas), not Japan; the 'Japanese' designation may refer to its ornamental style or a historical naming convention.
- 🌱 'Little Henry' is a dwarf cultivar specifically bred to remain compact, making it ideal for small gardens and container cultivation, unlike the species which can reach 6+ feet tall.
- 🌱 The flower spikes produce a sweet, honey-like fragrance that is especially pronounced on warm, sunny days and attracts a diverse array of pollinating insects.
