Fun Facts
- 🌱 Stewartia is named after John Stuart, 3rd Earl of Bute and botanist, and was discovered in Japanese mountain forests where it grows as an understory tree in cool, moist conditions.
- 🌱 The exfoliating bark is its own winter show—naturally shedding in irregular patches to reveal layers of contrasting colors underneath; this process should never be artificially accelerated or damaged.
- 🌱 Stewartia flowers are ephemeral and short-lived, often lasting just a single day, but the tree produces blooms continuously throughout the summer for a season-long display.
