Heat the water to 75–80°C (167–176°F) — do not boil. Add the white tea and steep for 3–4 minutes. Remove the tea bags or strain the leaves and let the tea cool to lukewarm.
Add the dried hibiscus flowers to the warm tea. Let steep for 5–7 minutes only, just until a light ruby color and gentle tartness develop. Strain out the hibiscus promptly to avoid harsh acidity.
While the tea is still warm, stir in 2 Tbsp honey until fully dissolved. Taste and add up to 1 additional tablespoon only if needed. Let the tea cool to room temperature.
Refrigerate for 1–2 hours until fully cold and balanced.
Fill glasses with ice. Pour over the chilled hibiscus white iced tea and garnish lightly with a few dried hibiscus petals and a thin strip of fresh lemon peel for a clean, elegant finish.
