Fun Facts
- 🌱 Hydrangea flower color is directly determined by soil pH—acidic soils (pH 5.5 and below) produce blue flowers, while more neutral to slightly alkaline soils produce pink flowers, making them natural soil pH indicators
- 🌱 Helleborus (Christmas rose) blooms in winter because it evolved to flower when deciduous shade trees lose their leaves, allowing winter sunlight to reach the forest floor
- 🌱 Many shade-tolerant perennials like hostas and ferns have evolved extremely efficient light-capture systems with larger, thinner leaves that can photosynthesize in low-light conditions
