1. Lilacs and Climate Study Marker

Inscription. Some plants' spring growth is triggered by light changes, but lilacs are primarily influenced by the rise in temperature. Scientists have utilized this trait in lilacs to study climate change over time. The lilac Syringa × chinensis 'Red Rothomagensis' has been monitored in 72 different sites across northeastern North America since 1965. Researchers documented when its buds, leaves, and flowers opened each spring. They found that the lilac's blooming cycle has advanced by several days, suggesting that spring is coming earlier.
